Testimonials

You’re the best thing that happened to us during the pandemic!

— Family who’s been working with me ever since

You really turned around [our daughter’s] relationship to math!

— Parent, Marin Academy

— K & J, Parents, Hamlin & Branson

“My confidence level has gone up a lot and my stress level has gone down because I know I can go over challenging problems with Kyla. I’ve earned an A in every class since working with her.”

— Student, 8th grade, Convent

“In addition to her deep knowledge, the joy and humor which she brings to any interaction is perfect for students. I highly recommend Kyla to any student who wants to learn challenging math with a fun and supportive expert as a guide!”

— Mark Shoemaker, Professor at Colorado State

“I truly appreciate how Kyla values depth over memorization—an approach that is rare and truly impactful. I would highly recommend Kyla to any student or family looking for someone who can nurture curiosity, build strong skills, and help students go beyond their classroom learning.”

— Nina, IB Teacher at Stuart Hall

“Kyla has been an indispensable source of academic support for both our middle and high school daughters. Over the summer, she even helped our high schooler master a full year of math, enabling her to pass the placement test and advance to a higher-level course. Kyla is AMAZING!”

— Parent, Hamlin & Branson

“Kyla is a strong mathematician and a kind, thoughtful educator. I trust her mathematical taste, teaching style, and fun-factor gauge.”

— Emily McCullough, former Director of the San Francisco Math Circle

“I would recommend Kyla (and I have!) as a math tutor because I know she delivers results and is an agreeable, encouraging teacher.”

— Parent of 7th grader at Hamlin

“We wish we had found you sooner!”

— Parent of Hamlin 7th grader

“We really benefited from Kyla’s consistent tutoring of our kids. We knew they needed enrichment and to be pushed, but knew we could not do it ourselves. We put them in Kyla’s hands and knew with great confidence that they would be doing exactly what we had hoped.”

— Parent

“My older child placed well in high school math after working with Kyla, and my younger child has not yet entered high school but got a near perfect score on the math section of the SSAT.”

— Parent

“I would recommend Kyla (and I have!) as a math tutor because I know she delivers results and is an agreeable, encouraging teacher.”

— Parent of 7th grader at Hamlin

“Thanks to Kyla’s intuitive and creative approach, our daughter has gained tremendous confidence and I dare say enjoys math and is doing great. Kyla became part of our family and was often the only person who could work with [our child] on a difficult day.”

— Parent of 4th grader at Hamlin

“I love the reports. They allow me to check-in and have math-related conversations with my son. I could connect his lesson with Kyla and what they did at school.”

— Mary Dennis, Parent of 8th grader at Children's Day School

“Kyla is patient, relatable, reliable, a good communicator and easy to talk to. I like that she role models that women are strong in math.”

— Parent of 7th grader at Hamlin

“Kyla teaches me in a creative way that’s not just telling me stuff. She is very understanding and helpful and makes the lessons fun.”

— Student, 7th grade

“Going to math class no longer gives me anxiety attacks, and I’ve stopped avoiding my math homework. I’ve gained a lot of confidence in my own ability to do math.”

— Student, CAIS, 8th grade

“It was a comfortable space where we didn’t have to feel judged or ashamed if we did something wrong.”

— Student, 7th grade, BEAM Summer Program

“The questions were frustrating but fun and I loved the challenge!”

— Student, 7th grade, BEAM Summer Program
