I have always enjoyed teaching and helping others to learn. My formal education includes a BS in Physics, a Masters in Photonics/Optoelectronics, and additional coursework in optics. I also have extensive programming experience. As a tutor, I am patient and I work to make the material interesting.

About me: I spent 10 years working for the Caltech/NASA Jet Propulsion Lab on advanced optical systems. This work included camera alignment for the Mars rovers Spirit and Opportunity. For the last 8 years I have worked independently and started three technology companies. I live in Washington, DC with my girlfriend.

Physics:

My first technical job involved calibration of an X-ray astronomy satellite. Since then I have worked on instrumentation and analysis for a number of astronomical and earth-observing science systems. There is a lot of applied physics in this work. I think I have a talent for visualizing physical concepts, and I incorporate this into my tutoring. Visualizations help with understanding and development.

Math:

Math has always been a strong point. I enjoy the abstractions inherent in math at all levels.

Programming:

I know approximately 10 languages. I emphasize Matlab in my profile since I use it almost daily for analysis and graphing. I have used Matlab extensively since 2000.

I look forward to hearing from you and helping you achieve success in your studies.

MATLAB

Matlab is widely used in academic research, engineering, and elsewhere. I love the language because it is so carefully designed, written and documented, so effective for high level scripting, and so adept at generating attractive figures. I have been using Matlab extensively since 2000, and currently I use it almost daily. I recently started two companies to license Matlab software I have written. I have taken classes in a number of programming languages, but Matlab is my favorite.

Algebra 1,

Algebra 1

Algebra 1 covers a lot of topics, such as equations, inequalities, functions, graphing, polynomials, factoring, and rational expressions. Many of these are interconnected with each other. There are a huge number of practical applications, and learning about them can help make the material fun. Let's work together to empower you in this class!!
Algebra 2,

Algebra 2

I enjoy tutoring Algebra 2 (aka precalculus, but minus trig in some curricula) because the subject is so empowering. Algebra 2 completes the formal study of the elementary functions - polynomial, exponential, logarithmic, rational, radical, piece-wise, and trigonometric. Parametric equations, vectors, and infinite sequences and series are also studied. Working together we can help you attain the confidence you need to succeed!!
Calculus,

Calculus

Calculus includes the formal study of limits, derivatives, and integrals (and sequences and series in the case of AP Calculus BC). With my background in physics I especially enjoy the study of calculus because of the deep connection between the two. And of course there are many practical, real-world applications. Calculus is challenging, for sure. But whether you are studying for AP Calculus AB or BC, or another version of the course, let's work together to help you conquer the subject and (hopefully) have fun at the same time!!
Physics,

Physics

Physics can be overwhelming, but I am here to help. Physics is a big step into a new way of thinking. Doing lots of homework problems is very important. I also try to show the big picture of how the concepts fit together and explain context. Physics is the most basic of all the sciences. Chemistry, biology, astronomy, etc. all have physics at their core. Kinematics, energy, momentum, rotation, waves, and electromagnetism are examples of key concepts. I try to make them interesting and fun! I am currently tutoring up through AP Physics 1.

SAT Math,

SAT Math

I tutor the math sections of the SAT. At our first meeting, I make sure each student is familiar with the wonderful set of online SAT prep tools created by Khan Academy (which is free) in partnership with the College Board, maker of the SAT. To create an organized study structure, I suggest the student or a parent use the tools to create a study/practice schedule appropriate for the student's planned test date. My approach for what comes next depends on the student, his/her preferences, his/her goals and his/her skill level. Sometimes a good start is a methodical check of the student's understanding and level of comfort with each of the 40 subtopics (grouped into four "domains" - "Heart of algebra," etc.) into which the College Board has divided the material students should know. Along the way I highlight concepts and formulas that, in my experience, frequently trip up students. I also provide a sheet of formulas to memorize. Identifying shortcuts is another skill we work on, and I have assembled examples of problems that can be solved more than one way. Another activity is review and talk-through of problems from practice tests students take on their own time outside of our meetings. The College Board provides 8 practice tests specific to the new SAT that I use.

ACT Math,

ACT Math

I tutor the math section of the ACT. Before our first meeting, I suggest students purchase the "Official ACT Prep Pack" (~$48, includes both a paperback book and access to "ACT Online Prep") and take the website tour. The tools on the website can be used to create a customized prep schedule based on the student's planned test date and whether the student prefers a "structured" or "adaptive" learning plan. This helps us organize our work together. My approach for what comes next depends on the student, his/her preferences, his/her goals and his/her skill level.

Trigonometry,

Trigonometry

Trigonometry involves trigonometric functions and graphs, inverse trigonometric functions, trigonometric identities, and angle formulas. The subject has millions of real life applications in lots of different fields including physics, engineering, geography, business, and more. Trig questions appear frequently on standardized tests such as the SAT and ACT. The subject can be difficult, and includes lots of functions with obscure sounding names. By the end you will understand what is so funny about the Onion headline "Nation’s Math Teachers Introduce 27 New Trig Functions." But working together hopefully we can make the subject tractable, fun, and empowering.

A Huge Help With My College Physics Course

I have not taken a Physics class in over 10 years. As an older student in a Post-Bacc program, some concepts take longer to grasp now than when they did when I was in college. I review all lecture and homework problems with Leonard. Unlike other tutors, he takes the time to write down all the steps in solving the problems and explains them. At the end of each session, I have a neat stack of his notes as well as mine, and these have been critical study guide tools to look back on!

Will, 14 lessons with Leonard

Excellent ACT math tutor

Leonard reviewed all the ACT math problems that my son got wrong on his prior practice tests. He explained everything very thoroughly and in an easy to understand way. My son was very happy with the session and wants to schedule another review session. Thank you!

Jackie, 11 lessons with Leonard

Knowledgeable and patient tutor

Leonard was very patient and thorough when working with our son on calculus. He was very responsive on email as well. We will definitely use him in the future.

Dana, 3 lessons with Leonard

Tremendous Help

Len has been a tremendous help in providing a clear understanding of my son's college calculus summer class. Since the coursework is condensed, Len's tutoring has been essential in understanding the materiel. Highly recommended.

Darren, 8 lessons with Leonard

Knowledgeable

My daughter informed me that Mr. Leonard's method of teaching has allowed her to understand the topics she was not able to comprehend when taught by her college professor.

Cynthia, 7 lessons with Leonard

Really helpful and versatile tutor

Leonard has worked with both my 6th grader and 9th grader, on everything from algebra 1 to AP calc to AP physics. The kids both like him very much and he's been really helpful and patient in tamping down some of the math anxiety.

Stephanie, 61 lessons with Leonard

Really patient and knowledgeable on the subject

Len explained statistics in a visual way so I not only understand the formulas but the underlying foundation. His explanation allowed me to see statistics in a new light and actually enjoy it. He is also very patient and kind. Definitely going back to Len. Thank you so much!

Agnes, 2 lessons with Leonard

outstanding teacher

Despite meeting with many matlab tutors, Leonard is by far the best matlab tutor I have ever meet with. He is great at providing examples and makes the material very easy to understand.10/10 would recommend.

Fahad, 1 lesson with Leonard

Very knowledgeable and patient

My son likes him for AP physics tutoring, very patient and of great help. Leon is flexible in his schedule which helps a lot for adhoc request as well. Prepared and knowledgeable tutor for kids.

Laura, 6 lessons with Leonard

A great teacher with lots of patience!!

In a matter of days, Leonard has helped me understand 3-4 weeks of material! He is patient, extremely knowledgeable, and able to work with my crazy school schedule. I am so very appreciative and thankful!
