PhD in Physics and Adjunct Professor in Orange County. High rate of 4's and 5's on AP Tests.

Derek was an incredible help to my son in calculus. He was extremely flexible with scheduling, which made a huge difference for us, and he really took the time to break down formulas in a way that finally clicked.

After working with Derek, my son brought his grade up to an A on his latest exam — a direct result of Derek’s ability to teach clearly and effectively.

What stood out most is that Derek is relatable and connects well with students. My son actually enjoyed the sessions and said Derek explained things better than anyone he’s worked with before.

Highly recommend Derek to anyone looking for a knowledgeable, patient, and effective tutor.

I highly recommend Derek for any parent looking to build confidence and skill in their child's math ability. After every lesson, he always follows up with a helpful breakdown of what they went over, what things were improved, and what things still need to be worked on. He's friendly and patient, and my son always enjoyed the lessons.

Great tutor! I went from scared of physics to getting A's on my tests.

Derek was awesome for my Calc-based physics class. Always explained everything in detail and made physics interesting and fun.
