About Tim

Tim's profile

Founder and Lead Tutor

I am a graduate of Stanford and Harvard. While I studied engineering and business, I have enjoyed Math since grade school when I was selected for an experimental program in Symbolic Logic conducted by Stanford’s Dr. Patrick Suppes, which formed the basis for Stanford’s Education Program for Gifted Youth (EPGY) and then Stanford’s Online High School.

I have been tutoring all levels of Math in both courses and standardized tests for the past 12 years, from Elementary Math to Calculus, SAT to GRE/GMAT, and Military ASVAB and Officer tests. My tutoring platform has earned the 3rd highest number of hours tutored in the nation in both 2020 and now 2021.

I have had the privilege of working with students as young as 5 and as young as 88. My students, including those who did not start out believing they were “good at Math,” have excelled in the following ways:

  • Finishing 7th grade Pre-Algebra as young as 8
  • Completing Honors Precalculus as young as 11
  • Earning A+100% in Geometry at Stanford's highly rigorous Online High School
  • Taking Calculus 5 at age 14 at junior college while concurrently enrolled in high school
  • Achieving a 9-8-9 on the OAR/ASTB-E and being offered the position of a Navy Pilot
  • Increasing ASVAB score from 28 to 50 in less than 3 weeks
  • Successfully completing the CSET (California Subject Examinations for Teacher) exam and overcoming a long-term condition of dyscalculia
  • Achieving a perfect 800 on the SAT Math section and increasing SAT Math score from 500s to 700s in just a couple of sessions
  • Increasing GRE Math score by 6 points (one student did so in 6 lessons and the other did so in less than 2 weeks)
  • Scoring a 94 on the ASVAB and increasing OAR score by 8 points in 5 sessions

I believe that establishing a strong foundation in Math is essential for students' future success and confidence – in high school, in college and beyond in their careers. And I believe that every student has the potential to be successful with Math. Creative approaches to Mathematics education that work well for gifted students also help students of all levels and backgrounds to succeed in Math.

I have worked with many homeschooled students who have succeeded to the point of being admitted to top universities. Many of these were able to follow an accelerated path, especially in Mathematics, due to the individual attention and encouragement to believe that their progress can know no limits. One was admitted to UC Berkeley at 15, graduated at 17 and got her masters in applied mathematics at 19. I understand the special opportunity that homeschooling offers and know how to equip and inspire the independent learner.

My philosophy is that mathematics provides a critical foundation for other learning. Young people can grasp advanced concepts early on. Adult students can rebuild and develop their tools, skills, and understanding. Each student is unique in background and mindset and deserves a tailored approach.

The select members of my highly-credentialed team share my teaching philosophy and commitment to excellence.

What Happy Students & Parents Say

  • Absolutely priceless

    "I could remember the moment that our daughter practically skipped downstairs. After months of frustration and some tears despite pulling mostly A's and B's in Calculus, all it took was one session to see my daughter smile again. We felt so lucky to have found Tim. Not only was he beyond accommodating when Jenna had a last minute event pop up for one of her sessions, he is kind, patient and has an amazing ability to distill complex concepts into something infinitely more easily understandable. It was absolutely priceless to see my daughter having lightbulb after lightbulb moments and gain the confidence that she has today. If your child needs help in math don't even hesitate to work with Tim. You'll be so glad you did!"

    Kathleen S. from Chula Vista, CA


  • Outstanding tutor

    "Tim is an outstanding tutor! He really knows his stuff and teaches SAT Math in such a simple way that it will make sense to anyone. In just a couple of weeks, he helped me score the 98th percentile on the SAT (improved nearly 200 points in total) and was admitted to Yale University! He is absolutely incredible and is the best tutor I have ever had. He is well worth the money. He is patient, very knowledgeable, and will cater his teaching style to the student. I am so happy I chose to work with Tim!"

    Walker B. from Denver, CO


  • Awesome with my eight and five-year-old

    "Awesome with my eight and five-year-old! Thank you Tim. It is obvious you have had time and experience working with young kids. Looking forward to continuing our engagement with you."

    Melanie C. from Palo Alto, CA


  • Very knowledgeable and helpful tutor

    "Tim helped my GRE Math score increase by 6 points in just a matter of 10 days! He describes each concept in a very patient and helpful manner and is extremely easy to talk to when you are having any misunderstanding. He also gave key strategies specifically for the GRE that I could not get from a prep book or class. Tim is extremely knowledgeable about math in an approachable way, and I owe my new math skills to him. Thank you, Tim!"

    Sarah Q. from Chicago, IL


  • Professional and experienced tutor

    "Mr. Tim’s experience as an educator showed in every minute he prepared me for the ASVAB. The scanned recap notes of his explanations he would send after each session were a great help. Thanks to his efforts I scored a 94 on my ASVAB!"

    Rajeev P. from Ridgefield Park, NJ


  • Knowledgeable and patient tutor

    "We went over some GRE quantitative methods and it made me wish I had had a tutor like Tim when I was in high school! Tim was very methodical and clear in his explanations and it took away the anxiety I often have around math. I’m looking forward to our next session."

    Patrick T. from Boston, MA


  • First "A" of the semester in AP Calculus after one lesson

    "After one lesson the night before the exam, my son got his first "A" on a test in AP Calculus after consistently getting "B's" studying on his own. We will definitely be continuing with Tim, whom my son really likes. Thank you!!!"

    Belinda B. from Houston, TX


  • Amazing Tutor

    "Tim worked with my 6th grade daughter who has struggled with Singapore math. After the lesson with Tim she asked if she could do another math session! Tim was super patient and she walked away knowing she CAN do math!"

    Cheri N. from Colleyville, TX


  • An Amazing & Patient Tutor

    "Tim is truly an amazing tutor. He took a little bit of time to get to know my daughter, who has some anxiety about tutoring, and turn the session into something she really enjoyed! He was able to present the information in a way that allowed my daughter to grasp the material and score her highest grade on a math test this year! He also provided the notes from the session that my daughter put into her notebook and used as study material. Thank you!"

    Jason R. from South Lake Tahoe, CA

  • Clearly knows what he’s doing

    "In our first lesson Tim was able to quickly understand my situation and study requirements, point me in the best direction for self study/prep material, and then immediately jump into insightful tutoring information that was directly applicable to the exam I'm looking to take. He then helped me create a simple curriculum to get me to my target score, and followed up our session with an email including all the notes, images, and concepts discussed during our online session. He’s clearly been doing this for a long time and does it very well."
