About Tessa


Bio

I'm Tessa, and I love learning and teaching Math! I have a B.S., M.S., and Ph.D. in Applied Mathematics and have over twenty-five years of experience teaching at University and High School levels.

I'm Tessa, and I love learning and teaching Math! I have a B.S., M.S., and Ph.D. in Applied Mathematics and have over twenty-five years of experience teaching at University and High School levels. I have taught a wide range of mathematics, from ninth-grade Geometry to Partial Differential Equations.

I'm exceptionally fluent at tutoring the following subjects: Algebra (all levels), Trigonometry, Geometry, Precalculus, Business Calculus, Calculus (all flavors, including AP AB/BC, and Calculus I, II & III), Intro to Statistics, Probability and Statistics, AP Statistics, Differential Equations, and Linear Algebra. I also tutor ACT and SAT mathematics.

I started tutoring other students when I was a mathematics major in college. When I took Calculus III, the school hired me as a math tutor for a few hours a week. I've either tutored or taught math in a classroom ever since. I've taught and tutored all the listed subjects at least once. I'm patient and good at explaining mathematics in plain language while at the same time building mathematics vocabulary, helping students see things in new ways, and building upon the innate number sense that we all have.

I know that being good at math takes practice, like a muscle you need to flex. I promote a positive mathematics mindset, help students build symbolic fluency, focus on conceptual understanding and the meaning of notation rather than manipulating it, and help students reduce test anxiety. I can even help with personalized interdisciplinary projects. I'm thorough, detail-oriented, don't rush students, and, above all, patient.

Good fit for my junior calculus student

Tessa was a great fit for my calculus student. We went through a couple tutors before we found her, but found her to be an expert in the subject and good at explaining difficult problems. Looking forward to preparing for the ap test with her.

Great tutor! very patient and helpful

Tessa is the best! She always takes her time in explaining problems, and she goes into detail as how we find the solution, making sure I understand each step. She is very patient and kind, she helps me so much!

Dina, 13 lessons with Tessa

Gifted and effective stats tutor!

Tessa jumped in to support my kiddo in their final 3 weeks of college intro to statistics. From their first session, Tessa had my daughter feeling more confident. She was able to quickly build my daughter’s skills and hone in on the areas she needed to improve. During those three weeks, with Tessa’s tutoring, my daughter’s grade went up one full letter. The final hasn’t been scored, but we are optimistic that she did quite well and we’ll see another gain in grade.

Expert in Induction and Algorithmic Thinking

Tessa is an incredible tutor who has helped me grasp the mathematical foundations of algorithm design, especially weak and strong induction. Before working with her, I struggled to understand the logic behind proofs and how to apply induction effectively. She not only explained the concepts clearly but also guided me through challenging proofs step by step, making sure I truly understood the reasoning behind each step. What sets Tessa apart is her patience and structured approach—she doesn’t just give answers but helps you build the intuition needed to tackle proofs on your own. Thanks to her, I feel much more confident in my problem-solving skills and ready to apply these techniques in my coursework. If you need a tutor who is knowledgeable, patient, and excellent at explaining difficult mathematical concepts, Tessa is the perfect choice! Highly recommend!

Very good AP Stats tutor

Tessa is very experienced AP Stats tutor. My daughter struggled to understand the materials in school, but Tessa always manages to help. I daughter tried out a few sessions at the beginning, and decided to continue with Tessa for the rest of school year, to prepare for AP.

Peggy, 21 lessons with Tessa

Very Knowledgeable

My Daughter has done seven one hour lessons with Tessa and she is very happy with her style of teaching. Tessa makes it easy to understand the material and she has more than one approach. Tessa does not get upset of make remarks if my daughter has a question; she explains it again or she shows her using a different way. We are very happy with Tessa.

Great teacher!

Worked well with my son to understand his stats worked and helped him to feel more confident going in to a test.

Kristi, 6 lessons with Tessa

Great first session!

Our daughter connected well and was more confident about the AP Stats unit she had trouble with upon completion! We’ve booked another session next week!! Thank you!

Katrina, 16 lessons with Tessa

Knowledgeable and explains concepts well

Tessa did a great job of breaking down the concepts where my son came away with a better understanding and went into to his test feeling more confident which resulted in a great result

Brian, 9 lessons with Tessa
