Bio

Extremely experienced and enthusiastic math tutor at your service! I have rare qualifications: a math PhD from Stanford, a record of exceptional achievement on contests, including an International Math Olympiad gold medal and excellent performance on the AMC and AIME, and more than a decade of tutoring.

Extremely experienced and enthusiastic math tutor at your service! I have rare qualifications: a math PhD from Stanford, a record of exceptional achievement on contests, including an International Math Olympiad gold medal and excellent performance on the AMC and AIME, and more than a decade of tutoring. I'm a creative and passionate educator committed having my students succeed and find joy in mathematics.

I have a very wide range of experience -- I've tutored kids from age 4 to college. I've taught college classes such as linear algebra and calculus, I've worked for Art of Problem Solving for 6+ years (including rewriting a class), and I have experience with the standard elementary curriculums, such as Singapore, Math Mammoth, Saxon, and Beast Academy. I've taught almost all the AoPS classes -- starting with Prealgebra, continuing through Geometry, Introduction to Number Theory and Introduction to Counting & Probability and through Precalculus, Intermediate Algebra, and Calculus. I'm also an expert on math competitions, including AMC 8, AMC 10, AMC 12, AIME, USAMO, IMO, Mathcounts, the Math Kangaroo, the Math Olympiad for Elementary Students (MOEMS), ARML, and the USA Math Talent Search (USAMTS)

I'm also an expert in accelerating gifted younger children. I homeschool my kids and my 7th grader recently got 1560 on the SAT. I've worked with kids who are finishing up elementary math at ages 6/7 and know how to move ahead with younger learners while preserving their enthusiasm for mathematics and making sure they get a solid, thorough education without conceptual gaps.

I also have experience helping math click for struggling learners. I've worked with neurodivergent kids and have handled executive functioning challenges for kids with ADHD. Nothing gives me as much satisfaction as seeing the "aha!" look on a student's face, and that's regardless of the subject they're working on or their mathematical ability.

Please reach out if you have a question. I look forward to working with you!

Approved Subjects

Algebra 1

Algebra 1

From my experience teaching both at the college and high school level, I know that algebra is the stumbling block that keeps many kids from higher math. As a result, I have developed an intuitive approach to algebra that allows a wide range of kids to get a deep understanding of the subject. I've even used this approach with younger kids and can confirm that it works much better than the standard methods!
AMC (Competition math)

AMC (Competition math)

I have a record of extremely high achievement on math competitions, including silver and gold medals at the International Math Olympiad. I also have more than a decade of experience training kids for the AMC 8, 10, and 12, as well as the AIME and the USAMO. Looking forward to sharing my expertise with you!
Geometry

Geometry

I'm an expert at geometry and excel at geometric reasoning. I have expertise starting from school geometry, through the AMC/AIME, and up until the International Math Olympiad (IMO). I'm a visual thinker and am very good at explaining geometric concepts and logic in a hands-on, accessible way.
Precalculus

Precalculus

I am extremely experienced at teaching precalculus. I have an intuitive approach to polynomials, exponentials, trigonometric functions, and logarithms that helps the kids internalize the concepts in a way that enables them to succeed in precalculus and thoroughly prepares them for calculus. I am also an expert at the Art of Problem Solving precalculus class -- in particular, I've taught the online class many times and have contributed to that curriculum.
Probability

Probability

I have a thorough probability background. I started out with math competition combinatorics and probability (AMC, AIME, USAMO, IMO), continued to a probability PhD from Stanford, and have taught the Art of Problem solving combinatorics & probability classes many times. I'm very good at explaining combinatorics and probability concepts in a hands-on way that makes them intuitive and clear.

If you're looking for "the one"...

Olena's it. Exceptional teacher with world class math skills. My teenage boys really enjoy working with her - talking through AMC 12 problems, geometry, pre-calculus and calc. Her easy facility with challenging math - along with her warm disposition - takes the discomfort out of learning something new and there's a productive buzz to their sessions together. Whether my boys decide to ask for her help with math competition problems, re-explain school curriculum topics, or discuss a subject more in depth, every minute is productive. Olena has taught loads of AoPS classes and had a really good understanding of how to conceptually build math understanding. She's also highly responsive. So, for instance, my son decided to take a Physics class that requires Calc as a prerequisite and - although he passed the entrance exam - he hasn't actually taken Calc. Olena is filling in the gaps to excellent effect. Bottom line: whatever your math tutoring need, I can't recommend Olena highly enough.

Fantastic tutor with a gift for teaching

Olena has been such a great tutor for my daughter. She’s incredibly patient and really knows her stuff—she can teach even the most advanced topics with ease. My daughter was struggling with some number theory concepts, and Olena explained them in a way that finally made sense. She also gave practice questions between sessions, which really helped reinforce what she covered in class. We’ve had an amazing experience with her, and I can’t recommend her enough. If you’re looking for someone who truly understands math and knows how to teach it, Olena is the one!

Outstanding Tutor Who Brings Out the Best in Her Students

Olena has been an absolutely exceptional tutor for our son. From the very start, she took the time to truly understand both his strengths and the areas where he could grow, crafting lessons that are both engaging and appropriately challenging. What makes Olena stand out is her ability to bring out the best in her students. Our son has always been interested in learning, but under her guidance, his focus, effort, and depth of understanding have reached a whole new level. She presents material in creative and effective ways, making even the most complex concepts accessible and exciting. Beyond their lessons together, Olena provides thoughtful and carefully tailored work for after class that aligns with his interests and keeps him pushing himself in a constructive way. She strikes a perfect balance between challenge and encouragement, keeping him engaged and eager to take on new material. We are incredibly grateful for her expertise and highly recommend her to anyone looking for a tutor who can truly elevate a student's learning experience!

Most qualified math tutor you can ever find

Olena is absolutely THE most qualified math tutor you can ever find anywhere. In my opinion she is way over qualified to tutor my children given her education background! She is very patient with my children and always makes the learning experience fun for my younger daughter. Olena can tutor math at any level and we feel really lucky to work with her!

Very knowledgable and super qualified

Olena has a rare qualification of, being International Math Olympiad Gold Medalist. My kid has been doing math contests for a couple years and I am glad we found Olena from wyzant. Besides herself being a IMO Gold Medalist, Olena also taught math in university and online at AoPS so she is very familiar with all kinds of math competitions. It is hard to find local math tutors with such qualifications and online remote learning does not have good result. I am very happy with Olena's one on one tuturing for my kid. High recommended.

Top-Notch Teacher.

Olena is a Top-Notch teacher! My daughter really likes sessions with her. She likes how Olena explains the material, and most importantly, she feels comfortable asking questions. As a parent and math major myself, I can see that Olena puts extra effort into preparing for her classes. When it comes to the material, she prioritizes quality over quantity—a rare quality in a teacher.

Knowledgeable, resourceful and patient tutor.

Olena had many resources and methods to teach challenging math concepts. She was very patient and made sure everything was fully understood. I will have Olena as a tutor for all future math needs! She is excellent!!
