Bio

After many years of teaching and over 2200 hours of 5-star tutoring, I have established myself as one of Manhattan's premier private tutors. I have helped hundreds of students achieve their SHSAT, PSAT, SAT, ACT, GMAT and GRE goals and secure their places at schools such as Stuyvesant, Groton, Harvard, Stanford, Wharton and Columbia. I have also helped students from Columbia, NYU and globally (online) prepare for their exams in Finance, Economics, Investments, Statistics and Econometrics....

After many years of teaching and over 2200 hours of 5-star tutoring, I have established myself as one of Manhattan's premier private tutors. I have helped hundreds of students achieve their SHSAT, PSAT, SAT, ACT, GMAT and GRE goals and secure their places at schools such as Stuyvesant, Groton, Harvard, Stanford, Wharton and Columbia. I have also helped students from Columbia, NYU and globally (online) prepare for their exams in Finance, Economics, Investments, Statistics and Econometrics. Many graduates with Econ majors have hired me to teach them Finance and Investment Theory and forego the time and expense of an MBA altogether. I also help students navigate complex real estate valuation and LBO spreadsheets for both classroom related learning and real life investing.

TEST PREP: Many of my students spend enormous resources with classes, tutors and self-study only to find themselves stuck at the 600/85% level. This happens, especially for the Math section of the exams, because they have practiced and reinforced a brute-force approach which takes too many steps, too much time and forces careless mistakes. I teach my students how to think efficiently and find the elegant solutions. Instead of spending 4 minutes on a problem and getting it wrong, imagine doing it in 30 seconds and getting it right! That's how you get to 780. Many of my students wish they had contacted me first instead of going with a cheaper option. In the end, I may seem expensive but I am actually cost effective because I get results.

I have three Ivy League degrees, and I am a retired finance professor and a 20-year Wall Street hedge fund manager. I have taught finance, economics, investments and business at the collegiate and graduate level. I love to teach. I won the teaching award while at Columbia Business School. I bring both advanced teaching skills and real world career experience to motivate the learning process. I know how to explain complex concepts in an easy to understand manner. I am easy to relate to and develop a long-term mentoring relationship with my students.

I struggled in high school. I know what that's like. Then, my parents hired a tutor, a PhD in Philosophy and Mathematics, and my life changed forever. My tutor taught me how to think clearly, efficiently and precisely. Most importantly, my tutor made learning FUN and EXCITING! I aced the SAT and later the LSAT. I scored 99.99+% on the GMAT. It was the top score in the country that year. I received numerous scholarships for my education. I won Harvard Law School's Litigation Competition and served as a prosecutor in Massachusetts. I won the Columbia Business School teaching award and became a professor of finance. I then had a successful career on Wall Street.

Now, I give back by doing what I truly love to do- help my students succeed. I have students of all ages. I home-schooled my own kids K-12 and got them into Harvard College early action. Invest in your or your child's education. It's worth every penny many times over. The benefits of a great tutor or mentor last a lifetime and are priceless.

I try to be flexible with time and often provide extra over time without charge. I do not charge a cancellation fee. I understand that life sometimes requires lessons to be rescheduled.

I meet my NYC students in their homes and my online students sometimes as late as 2 am or as early as 6 am depending on their time zones. I am selective and do not take just any student. If I choose to work with a motivated student, I will develop a mentoring relationship and often help with application strategies, interview training, and career advice after they graduate.

I am expensive but worth it. I am also flexible and sensitive to a budget. I have a two hour minimum but after that I will often give extra time for free. If you're excited about achieving your goals then contact me and leave me your number and we'll do a free call to get to know one another and explore how I might help you.

I look forward to hearing from you.

Business

I studied Law and Finance at Harvard and Columbia. I also taught Finance, Economics and Investments at Columbia Business School. I started a Wall Street hedge fund and ran all aspects of the business for 20 years until I sold it in 2007. During this time, I also founded and incubated numerous business start-ups. I have helped students with business plans, Income Statements and Balance Sheets. I have helped investors analyze investment ideas and build successful investment/trading portfolios.
Econometrics,

Econometrics

I have a PhD in Finance and Economics and taught business courses for many years. I have taken Econometrics at the doctoral level and have published numerous papers in Finance which use econometric analysis. I have tutored students in econometrics from Columbia and NYU as well as online students. If you need help understanding multivariate linear regressions or tests for multicollinearity, I can help you. I am very good an explaining complicated and difficult concepts in an easy to understand manner.
Finance,

Finance

I have a PhD in Finance from Columbia B. School. I taught there and ran a Wall Street Hedge Fund for 20 years. I have helped many students locally from Columbia and NYU in their Finance and Economics courses. I also help students online from all over the world. I can help you master Time Value of Money calculations and Central Bank Open Market Operations. I have also helped non-students who seek to gain an understanding in Investing and Portfolio Management including stock and Cryptocurrency (Bitcoin) portfolios.
GMAT,

GMAT

After semi-retiring from Wall Street, I have spent the past 5 years establishing myself as one of Manhattan's premier Test Prep Tutors. There are many tutors with Ivy league degrees and top test scores. However, this doesn't mean they excel at teaching others. I have focused my teaching career on how to effectively explain complicated concepts in a manner that is easy to understand. In 1991, I won the teaching award while at Columbia Business School. Quantitative Reasoning: The math portion of the GMAT is not difficult. If you study by yourself, however, or even with an amateur tutor, you are bound to get stuck around 600 level. This is because you are attacking the problems using the long, brute force way you were taught in school. For example, if you ever use the Pythagorean Theorem (a squared plus b squared equals c squared) you are wasting precious time and increasing the probability of making a careless mistake. My students are trained to look for one of the 4 classic right triangles (for example: the three, four, five right triangle) and never brute force the Pythagorean Theorem. Using this approach, they will see the elegant solution in 10-20 seconds and get it right leaving extra time for other problems instead of spending four minutes on a problem and getting it wrong! Most of my students come to me after hours of classes, tutors and self-practice. They tell me they are stuck and can't seem to break through. This is because they need someone who is an expert on the exam to show them three things: 1) the elegant solutions, 2) the mental/psychological traps set by the exam makers and 3) the common mistakes they, in particular, tend to make. Acing this exam is as much about knowing the material as it is about knowing oneself! Before trying to save money with all those classes, go with a tutor who knows what he is doing. I can help you achieve your goals and do so in a cost effective manner. Verbal Reasoning. Improving verbal skills takes time and effort. I teach my students how to practice correctly to make the most of their time. I have effective practicing strategies that will increase my student's proficiency in the least amount of time possible. It's a common mistake to think that just doing tons of problems will greatly improve your score. Analytical Writing. Learning to write well is essential for academic. When I was young, writing was a mystery to me. Then, my tutor taught me the fundamentals of clear, effective writing. It's confusing because, first, you need to learn all the rules of formal expository writing. You know, the five paragraph essay that starts with an Introduction with a thesis, has three body paragraphs each with a topic sentence, and ends with a conclusion. Then, you have to learn how to relax the rules and write as if you were telling a story. If you struggle with writing, I can teach you how to create a persuasive analytical essay in the time required.

Elementary (K-6th)

A child's development during the elementary school years is extremely important. There are two kinds of students with special needs, those who struggle with obstacles such as ADHD and dyslexia and those who are gifted. Both kinds of students are at risk in public and most private schools. Regular schools are forced to teach to the average student. If your child has special needs, they will not be well served by the limited resources of most schools. If your child is gifted, he or she will find themselves ignored and bored. My recommendation is to supplement your child's education with a private tutor or to take them out of school and home-school them. I have a PhD in Finance and a law degree from Columbia University. I taught business at the collegiate and graduate level. I have tutored students for many years. I also home-schooled my own kids K-12 and got them accepted to Harvard. During the home-schooling process, I hired a k-6th tutor and used various K-6th educational materials including the Houghton Mifflin Harcourt home-schooling series. As my kids got older, I hired various subject tutors to come to my home. Home-schooling doesn't mean the parent has to do all the teaching. Think of is as a private school at home where the parent is the headmaster. I love to teach. I have tutored many Manhattan elementary and middle school students during the last four years. I teach my elementary school students to love reading, writing and math. I also teach them how to hold a conversation with an adult. I teach my middle school students how to think critically and I also start them on SHAT and SAT prep. Most of my students go on to magnet or private high schools including Stuyvesant.

SAT Math,

SAT Math

The SAT Math test requires expert guidance. Sure, your high school junior is smart and gets straight A's. And yet, even if she or he loves math, why is it so hard to get a perfect score- the elusive 800. Without expert guidance, the more you practice the more you lock in a 600-700 score. Why? Because it's not what you know but how you think that gets you to 800. In other words, practicing the long, brute force way to do a math problem not only takes time but also increases the probability of a simple careless mistake. 650 means you know the math. 750-800 means you think efficiently, and know yourself. It's rare to get to 800 on your own. And not all tutors can get you there. Most tutors are paid to watch your child do problems. I teach my students how to think and see the elegant solution. Many of my students come to me after hours of SAT classes, SAT tutors and self-practice and tell me that no matter how hard they practice they can't break above the 700 level. I explain to them that it's not about knowing the math but about knowing how to think. I evaluate their strengths and weaknesses and create a plan to get to 780 or even 800! I have established my self as one of Manhattan's premier test prep tutors. In the last couple years, I have taken many students from 600 or less to 750 or greater. My students have been excepted to Harvard, Stanford, Columbia and other top schools. I have tutored and mentored many students on the SAT and the college application process including the interview. I prefer students who come to me early before developing bad habits by trying to study by themselves or in a course. My favorite student are English students who think they hate math. Amanda, for example, told me she hated math. After meeting for 4 months, she started to love math. When she got 770 Verbal and 750 on her math SAT, I was so thrilled for her. Now she could apply to any school she wanted. I have a PhD in Finance and a law degree from Columbia University. I taught business at the collegiate level.

Writing

Learning to write well is essential for academic and business success. When I was young, writing was a mystery to me. Then, my tutor taught me the fundamentals of clear, effective writing. It's confusing because, first, you need to learn all the rules of formal expository writing. You know, the five paragraph essay that starts with an Introduction with a thesis, has three body paragraphs each with a topic sentence, and ends with a conclusion. Then, you have to learn how to relax the rules and write as if you were telling a story. If you struggle with writing or just need a sharp eye for some editing, please contact me. I have a PhD in Finance and a Law degree from Columbia and Harvard Law Schools. I have taught numerous students ranging from elementary school students to doctoral candidates. I home-schooled my kids, K-12, and got them into Harvard Early Action. I have also helped business professionals with projects ranging from business plans to demand letters. I have often facilitated in crafting a well written letter that leads to a promotion or a higher severance. No matter what you need, please contact me to discuss how I might help you.

Elementary (K-6th),

Elementary (K-6th)

A child's development during the elementary school years is extremely important. There are two kinds of students with special needs, those who struggle with obstacles such as ADHD and dyslexia and those who are gifted. Both kinds of students are at risk in public and most private schools. Regular schools are forced to teach to the average student. If your child has special needs, they will not be well served by the limited resources of most schools. If your child is gifted, he or she will find themselves ignored and bored. My recommendation is to supplement your child's education with a private tutor or to take them out of school and home-school them. I have a PhD in Finance and a law degree from Columbia University. I taught business at the collegiate and graduate level. I have tutored students for many years. I also home-schooled my own kids K-12 and got them accepted to Harvard. During the home-schooling process, I hired a k-6th tutor and used various K-6th educational materials including the Houghton Mifflin Harcourt home-schooling series. As my kids got older, I hired various subject tutors to come to my home. Home-schooling doesn't mean the parent has to do all the teaching. Think of is as a private school at home where the parent is the headmaster. I love to teach. I have tutored many Manhattan elementary and middle school students during the last four years.

SAT Math,

SAT Math

The SAT Math test requires expert guidance. Sure, your high school junior is smart and gets straight A's. And yet, even if she or he loves math, why is it so hard to get a perfect score- the elusive 800. Without expert guidance, the more you practice the more you lock in a 600-700 score. Why? Because it's not what you know but how you think that gets you to 800. In other words, practicing the long, brute force way to do a math problem not only takes time but also increases the probability of a simple careless mistake. 650 means you know the math. 750-800 means you think efficiently, and know yourself. It's rare to get to 800 on your own. And not all tutors can get you there. Most tutors are paid to watch your child do problems. I teach my students how to think and see the elegant solution. Many of my students come to me after hours of SAT classes, SAT tutors and self-practice and tell me that no matter how hard they practice they can't break above the 700 level. I explain to them that it's not about knowing the math but about knowing how to think. I evaluate their strengths and weaknesses and create a plan to get to 780 or even 800! I have established my self as one of Manhattan's premier test prep tutors. In the last couple years, I have taken many students from 600 or less to 750 or greater. My students have been excepted to Harvard, Stanford, Columbia and other top schools. I have tutored and mentored many students on the SAT and the college application process including the interview. I prefer students who come to me early before developing bad habits by trying to study by themselves or in a course. My favorite student are English students who think they hate math. Amanda, for example, told me she hated math. After meeting for 4 months, she started to love math. When she got 770 Verbal and 750 on her math SAT, I was so thrilled for her. Now she could apply to any school she wanted. I have a PhD in Finance and a law degree from Columbia University. I taught business at the collegiate level. I have tutored students in SAT Math for many years. I also home-schooled my own kids K-12 and got them accepted to Harvard.

Test Preparation

GMAT,

GMAT

After semi-retiring from Wall Street, I have spent the past 5 years establishing myself as one of Manhattan's premier Test Prep Tutors. There are many tutors with Ivy league degrees and top test scores. However, this doesn't mean they excel at teaching others. I have focused my teaching career on how to effectively explain complicated concepts in a manner that is easy to understand. In 1991, I won the teaching award while at Columbia Business School. Quantitative Reasoning: The math portion of the GMAT is not difficult. If you study by yourself, however, or even with an amateur tutor, you are bound to get stuck around 600 level. This is because you are attacking the problems using the long, brute force way you were taught in school. For example, if you ever use the Pythagorean Theorem (a squared plus b squared equals c squared) you are wasting precious time and increasing the probability of making a careless mistake. My students are trained to look for one of the 4 classic right triangles (for example: the three, four, five right triangle) and never brute force the Pythagorean Theorem. Using this approach, they will see the elegant solution in 10-20 seconds and get it right leaving extra time for other problems instead of spending four minutes on a problem and getting it wrong! Most of my students come to me after hours of classes, tutors and self-practice. They tell me they are stuck and can't seem to break through. This is because they need someone who is an expert on the exam to show them three things: 1) the elegant solutions, 2) the mental/psychological traps set by the exam makers and 3) the common mistakes they, in particular, tend to make. Acing this exam is as much about knowing the material as it is about knowing oneself! Before trying to save money with all those classes, go with a tutor who knows what he is doing. I can help you achieve your goals and do so in a cost effective manner. Verbal Reasoning. Improving verbal skills takes time and effort. I teach my students how to practice correctly to make the most of their time. I have effective practicing strategies that will increase my student's proficiency in the least amount of time possible. It's a common mistake to think that just doing tons of problems will greatly improve your score. Analytical Writing. Learning to write well is essential for academic. When I was young, writing was a mystery to me. Then, my tutor taught me the fundamentals of clear, effective writing. It's confusing because, first, you need to learn all the rules of formal expository writing.

PSAT,

PSAT

Preparing for the PSAT is a really good idea. Most parents wait till the junior year before they start looking for an SAT tutor. I work with many juniors who have busy school and sports schedules. It takes time to improve one's test score and the more time the better. There are huge advantages if a student starts his or her SAT or ACT test prep by preparing for the PSAT in their sophomore year. Given the lighter schedule and the length of time available, I can improve their PSAT scores but more importantly build the foundation upon which they will Ace the SAT and ACT when the time comes.

Gifted and passionate teacher

JD brought unmatched passion and energy to the tutoring session. His in-depth knowledge of the subject matter and his years of teaching experience show in his adeptness at explaining concepts in ways they can be easily understood and remembered. He moved efficiently through the session, explaining concepts, and then working through problems to confirm understanding before moving on. His enthusiasm was contagious...he makes learning fun!

Innovative and thorough

JD tutors my daughter for the math section of the SAT. His approach to teaching is broad and conceptual, drawing on innate logic. The result is not only superior preparation for the exam, but an augmented ability to think more lucidly in any discipline.

Gianna, 4 lessons with Jd

Excellent teacher

He is very knowledgeable and explains very well. He has great material for practice. I learned so much during our two-hour session. I am going to take more sessions with him and I highly recommend him.

Elham, 1 lesson with Jd

Really smart and prepared

I am taking an extremely challenging course at NYU called Real Estate Capital Markets mainly about CMBS. I have been struggling to follow along the entire semester although I have done all the readings so far. Dr. P. was able to help me and was prepared for the lesson although I sent him all the material last minute the night before. He is very knowledgeable and applies real life concepts to the material making it easier to understand. I am looking forward to our next sessions. I would recommend Dr. P. 100 percent!

Gabriela, 8 lessons with Jd

Professional and effective

My tutoring session was two hours long and we covered a lot because JD knows how to convey ideas concisely and effectively. Once he sees that you understand a concept, he wastes no time jumping into the next; my brain was fried by the end.

Mio, 2 lessons with Jd

The man is incredible. His real name should be " Watson "

TVM,PV vs. FV,algerbraic equations. Made me privy to what I'm about to walk into at Columbia Bussiness School. Clear & precise understanding of a financial calculator to which I've never used. Always did everything in my head. Only downside was the venue. Very loud. only because the first choice was closed.

Unparalleled Tutor, Teacher, Mentor!

Providing a short review of Dr. Park is difficult because he has so many outstanding qualities include here! First, let me just say he is hands down the best tutor you will ever find! Period. His theoretical and practical knowledge of all aspects of finance, investing, economics and more is of the highest level. In addition, he brings years of teaching and tutoring experience to the table which was evident from our very first session. His ability to understand and tailor his teaching style to my particular learning approach and learning difficulties has been tremendously helpful and something I never got from my teachers in school. He really strives to help me to not simply memorize my way through material but to develop a rigorous mental platform to be able to understand key concepts and formulas both at the conceptual and applied level. He is also extremely warm, friendly, and supportive. I always look forward to our sessions and plan to continue to work with him for the foreseeable future.

Awesome tutor

Dr JD was clear, to the point, super patient and understanding and most of all-he knew all the material backwards and forwards. He is one of the best tutors that I have ever had.
