With a deep commitment to student success that began in 2000, I have spent 26 years providing intensive, one-on-one private tutoring to thousands of learners. Overall, my mission has always been to demystify advanced concepts and transform academic anxiety into genuine confidence. Whether guiding a high schooler through honors geometry, mentoring a university student navigating organic chemistry mechanisms, or building a targeted strategy for the ACT, SAT, or GRE, I meet every learner exactly where they are. I specialize in helping diverse students, including those managing learning differences like ADHD or navigating chronic health challenges, build the executive functioning and consistent study habits necessary to thrive.

My own rigorous study included a BA in biology, chemistry, and mathematics with Summa Cum Laude honors from Manhattanville College, followed by a MS in Mathematics from New York University. Inspired by exceptional educators, I developed a patient, multi-perspective teaching approach where I break down intricate ideas visually and analytically until the material clicks. This includes leveraging dynamic graphing to make calculus intuitive. I focus deeply on the underlying mechanisms behind formulas, to ensure students understand exactly why a mathematical or chemical process works.

To carefully align sessions with a student's classroom experience, I proactively tailor lessons according to their specific textbook and professor's guidelines. We use active retrieval techniques to keep core theorems at their fingertips. This methodical system has consistently driven remarkable turnarounds, from helping struggling students secure rapid exam recoveries to coaching learners toward top grades in accelerated courses. I aim to foster independent analytical thinking and provide a supportive, stress-free partnership that helps students master advanced STEM subjects and conquer test anxiety. Hundreds of five-star reviews and a legacy of rapid grade turnarounds prove that these adaptive methods work.

ACT Math

ACT Math

I began my standardized test prep career as a classroom instructor and private tutor for major national organizations like The Princeton Review and StudyPoint. Over the last two decades, I have refined these institutional methods into a highly individualized approach, helping independent students throughout New York City and Central Ohio maximize their scoring potential. My experience includes guiding domestic high schoolers aiming for top-tier universities, students with intense schedules, and international transfer students adapting to American standardized testing systems. My method begins with a rigorous diagnostic analysis of a student's prior ACT attempts or practice tests. I do not sugarcoat the work required; instead, I pinpoint exact structural and conceptual math weaknesses to build a transparent, highly targeted lesson plan. By introducing foundational math theorems alongside time-management pacing strategies, I give students the concrete tools they need to attack the exam with absolute confidence. Past parents have consistently highlighted that this data-driven, honest approach dramatically alleviates test-taking anxiety and drives significant, measurable subject score improvements. Serious students have seen scores jump from 24 to 33 in as little as 10 sessions.
ACT Science

ACT Science

I was trained to tutor in ACT prep through my work as a former tutor and test prep instructor for StudyPoint, Inc. and The Princeton Review, Inc., respectively. Since then, I have developed my own approach and tutored several students independently in New York City and in Columbus, OH for the ACT. I have also successfully tutored students that wanted to gain admission as transfers from schools outside the United States. Depending on my students' strengths, schedule, and availability, I can develop individualized test prep sessions for those interested in preparing for the ACT, as a whole or just the math and science sections.
Algebra 1

Algebra 1

As an experienced tutor and honor's math major, I am well acquainted with the material covered in algebra and prealgebra courses. I have also taught algebra I to adult students at career colleges and middle and future high school students in summer enrichment programs. We usually go over: arithmetic of real numbers; fractions, decimals, and percents and related word problems; exponents, powers, and roots; order of operations; functions; solving linear and quadratic equations; graphs of linear equations and their different forms, including slope-intercept, point-slope, and standard form; inequalities; systems of inequalities and equations; polynomial addition, subtraction, multiplication, and division; and factoring in all of its forms.
Algebra 2

Algebra 2

As an honors mathematics graduate from Manhattanville College and a Master of Science recipient from New York University, I am uniquely equipped to guide students through the critical transition of high school Algebra 2. This course represents a major leap in complexity, introducing abstract concepts like conic sections, complex fractions, logarithms, matrices, and polynomial theory. I focus on breaking down these intimidating topics into accessible, bite-sized pieces, ensuring students understand the underlying mathematical mechanisms rather than relying solely on shallow rote memorization. My approach is highly effective for both students who are falling behind and those looking to get ahead. For instance, I have successfully coached students through accelerated summer terms, helping them master a full year of Algebra 2 curriculum in a single month to finish with a flawless final grade of A. By cultivating independent analytical habits, emphasizing consistent practice, and maintaining a supportive learning environment, I help students reduce their math anxiety, fill in foundational gaps, catch up on missing homework skills, and achieve rapid grade turnarounds.
Calculus

Calculus

With a MS in Mathematics from New York University, my experience in teaching calculus spans the entire academic spectrum from AP Calculus AB and BC to high-level multi-variable university courses. Over the last two decades, I have successfully tutored students at institutions including Columbia University, New York University, The City College of New York, and The Ohio State University. Because calculus numbering and notation vary widely between high schools and universities, I proactively align every session with the student's specific professor, syllabus, and textbook guidelines. My tutoring philosophy is centered on visual modeling and deep conceptual understanding, which is highly beneficial for visual learners or students managing learning differences like ADHD. I use dynamic graphing techniques to transform abstract derivatives and integrals into intuitive concepts. My track record includes engineering massive, rapid grade turnarounds, such as taking a student from failing quizzes to securing an A on their exam the very next day. Whether a student lacks a traditional precalculus background and is simply fighting to pass an accelerated summer course, or is a university student aiming to maintain a near-perfect average, I provide the tailored frameworks and stress-relief tips needed to master the material and achieve an A.
Chemistry

Chemistry

I have tutored college and AP chemistry students since 2005. I currently help advanced high school students in the Columbus area . Over the last few summers, I have also helped students at Colgate University, Long Island University, The Ohio State University, and Columbus State Community College with their coursework in general/introductory chemistry. Depending on demand, I can also help with organic chemistry.
Common Core

Common Core

I have helped students in Ohio pass their state tests in accordance with Common Core standards. From the OGT to the STAR tests and beyond, I go over practice tests provided by students and break down the key concepts they need to know following the methods and explanations that demonstrate full analytical comprehension of the fundamental concepts of algebra, geometry, trigonometry, and calculus.
Elementary Math

Elementary Math

I've always enjoyed math because I found it challenging. If that's not your experience, that's perfectly okay. I am patient and will help you learn the material thoroughly if you put in the time and effort. Practice makes perfect. I've helped both younger and adult students learn these concepts. From addition of three-digit numbers to improper fractions and back to long division, it will all slowly makes sense, but it's a cumulative effect that takes discipline and consistency.
Geometry

Geometry

I enjoy helping students with geometrical proofs. You have to make sure each statement logically follows from those that precede it. Geometry is a great course in which students explore the concepts of congruency and similarity of figures in the plane as well as 3-dimensional space. We also get a chance to study problems related to distances, areas, and volumes while also learning about symmetry transformations. The properties of circles, quadrilaterals, and triangles are fascinating, and with plenty of practice problems, students learn to appreciate that fact as well.
Linear Algebra

Linear Algebra

I have plenty of experience performing Gaussian elimination and calculating determinants. I also know how to find the eigenvalues and eigenvectors of a matrix or linear transformation. I also have experience working with unitary, symmetric, skew-symmetric, and other types of matrices. Gram-Schmidt orthogonalization is a bit tedious, but it's doable. Working with the theoretical aspects of fields and vector spaces are actually my favorite aspects of this subject. I am familiar with some applications and the basic uses in coding theory. (Nonetheless, I currently don't have solid programming skills needed to help students interested in numerical analysis applications.)
Prealgebra

Prealgebra

I have helped scores of middle schoolers, students in junior high, and even university and community college students with prealgebra in central Ohio. I have also tutored prealgebra students in Westchester County, NY and nearby Connecticut. Moreover, several of my students have now successfully completed honors algebra courses and beyond.
Precalculus

Precalculus

Precalculus serves as the foundational bridge between algebraic mechanics and the abstractions in the land of calculus. I specialize in helping high school and college students navigate this fast-paced curriculum, which covers intensive topics ranging from analytic geometry and families of rational or logarithmic functions to complex trigonometry and vectors. Because these courses demand a massive amount of material comprehension in a very short timeframe, my approach balances the perfect amount of structured academic challenge with unconditional patience. I work closely with my students to identify hidden foundational gaps, replacing anxiety with consistent, targeted practice. Rather than allowing students to treat mathematical steps as rigid rules to blindly follow, I push them to understand the actual meaning behind these processes. To build exam endurance and confidence, I routinely craft customized sample problem sheets and guide students through timed practice drills. This methodology helps diverse learners unlock underlying mathematical patterns, leading directly to higher test scores and a seamless transition into advanced placement STEM courses.
SAT Math

SAT Math

My experience with standardized test prep began as an undergraduate instructor for The Princeton Review, where I mastered the core strategies of the exam. Since relocating to Ohio, I have continuously updated my methodology to align perfectly with the latest digital versions and formatting changes of the SAT. I have guided hundreds of students through the changing math sections, helping them translate their effort into elite-level scores. I split my practice between students seeking a rapid, efficient strategy refresher and competitive scorers aiming for selective university admissions and merit scholarships. For long-term students, I assign targeted homework, provide active retrieval drills for critical geometric and algebraic theorems, and teach unique elimination strategies to completely remove test-day ambiguity. My dedicated students routinely break through score plateaus to achieve math marks of 700 or higher, building the academic confidence needed to master the exam.
Spanish

Spanish

I am a native Spanish speaker who completed bilingual elementary and high school education in the Dominican Republic. I am completely fluent as I can read, write, and speak in Spanish. In terms of academic units in the US, I also scored 80/80 on the College Board CLEP exams in Spanish and earned 12 college credits equivalent to 4 semesters of introductory and intermediate Spanish necessary for my alma mater's general education requirements. In Ohio, I mainly tutor students from the Pickerington, Reynoldsburg, and Columbus high schools who are taking required foreign language courses. Some of my Ohio State math and science students also ask me for help if they need to take Spanish for one of their general education requirements. I have also helped adult learners in the area with their conversational Spanish skills for their trips to Peru and the Caribbean. In the past, I also translated legal and technical documents from English to Spanish and from Spanish to English. I have also worked with my own online students. These clients are usually seeking occasional conversational practice with emphasis on correct pronunciation and accent modification.
Trigonometry

Trigonometry

I enjoy the algebraic aspects of manipulating expressions with trigonometric functions. I love proving identities; ever since I took my first lessons in trigonometry in high school, I can't get enough of these types of problems. Since I took Calculus, Differential Equations, Complex Variables and Abstract Algebra later on, my fondness for trigonometry has not dwindled, but grown.

Invested and Supportive Linear Algebra Tutor

I can’t recommend Stefano enough. From the very beginning of the semester, he was clearly invested in my success in linear algebra. Right away, he asked for my textbook, syllabus, and course materials so he could make sure everything he explained matched exactly with what I was learning in class. Throughout the semester, Stefano consistently tailored our sessions to my coursework and helped me actually understand the material instead of just going through the motions. He encouraged me to take the theorems seriously and helped me see how they connected, not only to the section we were on but also to earlier chapters when it made sense. That made a big difference in how I approached the textbook and built confidence in studying on my own. There were even times right before an exam when I really needed extended help, and Stefano was willing and able to meet for long sessions, even up to four hours. After each exam, he always checked in to see how I did, which meant a lot and showed that he genuinely cared. If you're looking for a tutor who really commits to your success, Stefano is that person!

Oh wow, Ella! Thank you so much for this incredible and thoughtful review. I deeply appreciate how much you noticed all of the small details that went into tailoring the sessions. I am so grateful to learn that you found this approach to be beneficial and that it helped you build your confidence. Yes, I want you, and all of my students, to succeed in your academic endeavors and get the most out of every tutoring session. I look forward to working with you as we continue to study eigenvalues and eigenvectors! :D

Incredible tutor!

Stefano was very instrumental in my sons success in college level calculus. My son is a very visual learner and Stefano made it easy for him to see using graphs and helpful tips. He also had many helpful tips about how to relieve the stressors that come along with college and calculus. Stefano worked diligently to make sure my son had complete understanding of each topic while encouraging him every bit of the way. He has an incredible gift in meeting students where they are and bringing them forward I highly recommend Stefano to all types of students!

Shelly , 19 lessons with Stefano
Tutor responded:

Thank you so much, Shelly! It was my pleasure to help Clayton. We covered a lot of material in only 6 weeks, haha. I am grateful that Clayton let me know when he needed to take breaks after we had been working on derivatives and integrals for a few hours. Calculus, ✔️!

Knowledgeable and Helpful

My daughter is about to graduate high school this coming May. She was originally struggling with her first Chemistry class when I reached out to Stefano. She had never needed a tutor before, so she was reluctant to give it a try. She started working with Stefano in the fall and continued into the spring semester, receiving help in calculus. She usually met with Stefano about once a week. He was helpful in reviewing and answering any specific questions or problems she had about the material. He was patient, always on time, and very entertaining. Anyone struggling in AP or CCP courses should defiantly consider giving Stefano a try!

Karli, 67 lessons with Stefano
Tutor responded:

(Just noticed this response feature, lol.) Thank you so much! It was a pleasure working with Karli. I appreciated that she was always prepared and knew exactly what she wanted to work on first. It made tutoring go very smoothly and efficiently, especially when we worked on the grammatically-picky PDF assignments for her calculus class, hahaha.

Amazing

Stefano provided just the right amount of support and challenge. He's my go to for multiple advanced subjects. Highly recommend. Advanced placement chem and pre calculus.

Improved Algebra 2 Grade

Alex is doing very well working with Stefano. Algebra two grade has definitely improved. We are still having problems with Spanish 4, but that has more to do with Alex not being timely with turning work in and the teacher taking points off. Alex now has the attitude that he is just going to fail Spanish and there is nothing that we can do about it. I think he has unfortunately had some teachers that have not been able to pick up on his real needs and he has just slipped through the cracks. The public school systems is not perfect for all, and for Alex with Spanish this is the case, never the less, as I have said to him, we must get through this school year and try not to fail. He does not want to accept the fact that it does make a difference to get the homework turned in and turned in on time. Maybe Stefano could help him understand the importance of turning homework in on time, that it does make a difference.

Awesome, Amazing, Reliable, Patient, Personable!

There aren't enough words to describe how happy we are with Stefano as a tutor. My daughter recently used him for her college Calculus class and he exceeded our expectations. My daughter took Calculus over the summer and had never had Pre-Calculus, so she knew the class would be difficult. She was hoping for the required "C" in the class to get the transfer credit. Stefano was so encouraging and told her she could do better and was right! She got an "A" in the class thanks to him (and her hard work). Stefano was extremely patient and encouraging, which built her confidence. Not only did he know the material but more importantly, knew how to explain it to her in a way that she understood. I always received detailed feedback on the material they covered which explained her strengths as well as areas she needed to work on. Every time I contacted him, I heard back from him within an hour. It was obvious he genuinely cared and wasn't just doing this because it's his job. My daughter has used a lot of math tutors through the years and he is one of the best! I would highly recommend him.

Kandi, 94 lessons with Stefano

Turned my son's school year around!

My son was struggling this year but was reluctant to get help. He was having trouble getting his work done and turned in on time. We finally convinced him to try tutoring. Stefano has done a wonderful job with our son. He was able to explain the concepts he needed to get through math and chemistry assignments. He is extremely patient and always on time. Our son has chronic health issues that make it difficult for him to concentrate. Stefano was very understanding and kind about this. Last semester without Stefano, our son was only able to get the minimum amount of work done to pass. With Stefano's help this semester, he turned in almost all of his second semester work, even in the subject that Stefano wasn't tutoring him in. Stefano helped him get back on track and have a far more successful end of the school year. It was a great relief and he couldn't have done it without Stefano's help. We highly recommend him and are so grateful that he was able to make such a difference for our son.
