Experienced Tutor for Math, Statistics, and Computer Science
I was a graduate student in mathematics at Caltech and a postdoc at Columbia University. I left academia to work in industry, but I enjoy teaching. I have written dozens of articles and a book on applying mathematics for general audiences. I'm working on a parent's guide to algebra and book on applying economics to improve environmentalism. I've tutored mathematics, statistics, economics, computer science, and programming since 2013 on other sites.
My goal is to make the material make...

Knowledgeable and Patient Tutor
Douglas was very patient and able to break down basic concepts of decision theory. I did not have a background in statistics and he was able to explain it and relate it to the real world.

A genius who knew infinity
First and foremost, Douglas is a very smart, talented guy, and a genius from my perspective. He can solve all types of tough problems in college level applied math and engineering math and even capable of extending this ability to graduate level. I had many tutors in Wyzant but almost none of them can answer all my problems in a sufficient level. Douglas is the first guy who can do so. Secondly, he knows how to teach! he can approach the problems in a way that students can understand with their limited knowledge base. Lastly, he is very focus and responsible during the session that makes u feel every minute worth the penny you u paid.

Knowledgeable and Provided clear explanations
I learned how to use Excel to create and solve word linear programming problems. He made it super simple and has extensive knowledge in the area, this was evident in his tutoring session.

Very knowledgeable and concise
Was able to show clearly how to solve the difficult problem in a relatively short period of time. Explanation of concepts, his analysis and ensuing strategy for solving were excellent. Will definitely use him again.

Knowledge, patient, and kind tutor
Douglas was really willing to make time for me, even though he was already very busy which I really appreciated. He's good at explaining problems and answers questions as well as asks what we know and think the solution might be and helps work out what problems together at a good pace.

Best Tutor out there
I hesitate to write this review because Doug is already busy enough and if more people use him it will be hard for me to get on schedule. However I have to give credit where credit is due. Doug is very patient, very smart and very hard working. He explains things so that even the least knowledgeable student can understand. I have siblings in college and I have already told them they should reach out to Doug for help when they get to these kind of classes. Doug’s services are worth every penny and more.

Great Calc Tutor
My son continues to learn a lot from his time with Doug (multivariable calculus). Doug is able to find problems that help explain the big picture, which is really great for my son's learning style.
