Have you ever had a teacher who didn’t seem to like teaching? That’s not me. I love helping my students do well.

After getting my degree from Caltech, I worked as a programmer at NASA. Eventually I started teaching the rocket scientists to code. I loved it! I left NASA to become a full-time tutor working with students.

I give lessons both online and in person in the Pasadena, Calfornia area.

Testimonials

Mike has been helping me to succeed in my college coding course. He often uses real world examples to find ways of relating the material to something concrete and understandable. He encourages and helps you to use problem-solving skills. As a tutee, you are an active participant in the lesson, and not just an observer/listener.
EricaCollege student
Mike is a brilliant, dedicated, passionate tutor who excels in teaching complicated concepts in a clear, simple manner. He has tremendously helped my daughter conceptually learn what she needs to know for her computer science class, and he continually challenges and encourages her to really understand the material at a deep level, not surface level. Mike is a rare gem, and we are so lucky to have found him!
AudreyMother of high school student
I’ve been working with Mike to improve my knowledge of Python. His depth of knowledge means that I’m never stuck, and at the same time given the space to wrestle with a problem long enough to understand it more completely. His focus isn’t just on memorizing the language, but helping me think like a computer scientist which is already giving me the capacity to code independently.

We feel extremely fortunate to have found Mike as a coding tutor for our 7th grader. Mike is knowledgeable, responsible and a very talented teacher. He instantly knows what his student’s needs are and works patiently to elevate them. I’m seeing a difference in my son’s confidence and love for the subject.
VivianMother of 7th grade student
Mike has been a great tutor for my son. He's professional, knowledgeable and patient. He pays attention to the details and is meticulous in his approach and expectations. My son has benefited greatly from working with Mike and is well prepared for more advanced classes and even an internship or coding job, while still in high school. We are so happy we found Mike, and have recommended him to some other friends, who have also benefited from his experience and methods. If you are looking for a tutor that is thorough, competent and thoughtful, Mike is the guy!
BonnieMother of high school student
Michael is an excellent Python teacher and great guy. He made the concepts clear and I learned a lot in our session. I look forward to working with him in the future.
MattAspiring coder
Mike is a rare find. He helped my son (high schooler) tremendously even in his first lesson, and my son went on to score a 5 on the AP Computer Science test. Mike is analytical and can quickly assess student's level of understanding. With that he was able to explain difficult matters to my son in a way he understood and appreciated.
SteveFather of junior high school student
Mike led me through an introduction to data science including scatter plots, linear regressions, transformed variables, histograms, and KDEs. I had only a little prior knowledge before working with him and feel I have good grasp on the material now. I’d recommend him to anyone eager to learn.
BethData science student
My son got a perfect score on his final, bringing his final grade from a B to a 99. I can't tell you how thrilled I am and how grateful I am to you for making this happen.
SameenaMother of high school student
Michael and I met because I didn’t understand my Python assignment. We had gone over the pre-baked code and discussed ways to alter it. While discussing things Michael had caught on the my fundamental skills we’re not up to par. We went away from the assignment and started doing some skill drills and discussing the code. The reinforcement that Michael had given me helped highlight what I needed to do on the assignment.
