OChem, Calc, ACT/SAT/GRE-years of exp. w/all ages, former OChem TA@UCB

I am a former TA for organic chemistry at the University of Colorado at Boulder; if it's OChem you need help with, you can't do much better than me! At this point, I have helped many students increase their ACT scores by up to 5 (One from 25 to 30!) and their SAT scores by hundreds. If you're looking for a tutor to help your almost-adult optimize their university applications, I am the best available! I am a 28 year old lover of language, science and mathematics pursuing a career in biochemi...

Patricia V. from Longmont, CO

David is able to simplify difficult concepts and make them clear to the student. He reinforces a particular concept by giving the student as many problems as necessary so the student can demonstrate a clear understanding of that concept. Our son says that David challenges him and he now views math in a positive manner. Wish our son had met David sooner!

Stuart M. from Boulder, CO

Although David was not a bad tutor once he actually showed up for a session, he was near impossible to communicate with. He did not answer emails promptly, was routinely late, and twice completely missed the very clearly set meeting time. Given his unprofessional behavior, I cannot recommend him as a tutor at this time.

Taylor C. from Parker, CO

David is an excellent tutor who is not only kind, encouraging, and patient, but also incredibly well informed and great at articulating material. It was really awesome how he helped me conceptually understand some concepts from Chem 2 instead of just turning to straight memorization like most people do. Also, he's very flexible and very approachable, on point and very focused, very friendly and easy to talk to. I highly recommend him as a tutor!!

Denise J. from Aurora, CO

David is so patient with my daughter! After spending a few lessons with her, he is figuring out different ways to help her understand what her math teacher refuses to take time to explain. I really appreciate what he has done so far! I would highly recommend Dave!

Kiana Y. from Boulder, CO

David was very helpful and patient. He takes the time to thoroughly explain concepts and checks to make sure it makes sense. He's great at providing alternative explanations and I found him to be very helpful!

Elizabeth D. from Golden, CO

David quickly assessed the needs of the student, understood what needed to be done to help, and already started on a plan to help him.
