Looking for extra help with college / high school math or physics, or college computer science? Perhaps that AP Calculus or Physics exam is looking like a challenge, or your son or daughter would like to improve their SAT scores? I have helped hundreds of students around the country make sense of calculus, discrete math and physics, to name a few popular subjects...check out my reviews and ratings. It's so great when I hear my students tell me they passed that hard mandatory class for their major, got an A on a big test, a 5 on an AP exam, or a 1440 on their SAT. I have a Master's in Computer Science from Stanford, and enjoy helping people learn about math and computer science, as well as related subjects like physics and SAT prep.

My specialties include college / AP classes like calculus and physics, as well as college classes for discrete math, computer architecture, and algorithm analysis. If you find yourself struggling with a challenging math class or challenging teacher, or just need a refresher in trigonometry, probability and statistics, or precalc to get through more advanced math, I would be a great choice to help you. My students appreciate my approach with lots of patience and positive reinforcement.

I have a flexible schedule, and can meet you or your students online, which is the most popular option, or in person after school, or during the day if that's more convenient. Most of my in-person students meet with me either at the library or in their home. At this point, I have a number of regular weekly clients who get priority for future appointments, so not all times shown in the availability list below are schedulable for new clients, but I would be happy to work with you to find a time that would work for you.

My preference is to work with students who want to improve performance in a class or for a standardized test over a series of regular sessions, as opposed to one-time help for a class assignment or test. You might reasonably expect a one-letter grade improvement fro

On Wyzant's platform, I often tutor courses in boolean algebra / digital logic as well as computer organization and assembly language. I am competent to consult on architecture and engineering topic including security and performance engineering. I have thirty year's work experience as a professional software engineer, developing and manage software engineering efforts using a variety of languages and operating systems. My specialty is systems software, especially operating systems, networks and databases. I have an MSCS from Stanford in Computer Science, as well as a BS is Computer Engineering from the University of Michigan.
Computer Science

Computer Science

I enjoy teaching computer science material, especially including some of the more theoretical subjects like data structures and analysis of algorithms, as opposed to primarily teaching programming language constructs. I have a Master's degree in computer science from Stanford, and thirty years professional experience in computer engineering. I work as a systems architect and help mentor junior developers. I was a teaching assistant at the University of Michigan as an undergraduate.

Calculus

I am among the top in-person calculus tutors in the state of Virginia, while also doing extensive online tutoring for several years on Wyzant and other platforms. (Not to mention that I am a Jeopardy winner, too!) I have helped dozens of students in person and many more online with calculus problems, including differential and integral calculus of a single variable (i.e. College Calc I/II, as well as high school AP AB/BC), including limits, differentiation and integration techniques, word problems, and series. Please let me know if I can be of some help, and we can discuss how to set up a session at your preferred time. Final exams and AP tests will be here before you know it!

Physics

I am among the top in-person physics tutors in the state of Virginia, while also doing online tutoring for several years on Wyzant and other platforms. (Not to mention that I am a Jeopardy winner, too!) I work with a lot of students in first-year college programs, as well as AP Physics 1 and AP Physics C programs. I have helped dozens of students in-person and many more online with physics problems, especially involving dynamics (laws of motion, energy conservation, rotational dynamics, momentum, etc) but also waves, electricity and magnetism, and basic optics, thermodynamics and fluid dynamics. If I can be of some help, please write to me and we can set up a time to discuss your problems.
Precalculus,

Precalculus

As you can see from my profile, I do a lot of work with calculus and physics. Precalculus is the foundation for these subjects, covering functions, polynomial roots, and especially trigonometry: sin / cosine / tangent, complementary functions, unit circle, identities, equations, formulas and so forth. I would be happy to work with you or your child on precalculus and get you ready for whatever comes next!
SAT Math

SAT Math

As a recipient of a perfect 800 score on the math SAT back in the day, I know what it takes to get through this type of high-stress test. I can help you review the key concepts including ratios, probability, geometry and graphs, as well as help with test-taking strategy, such how to make best use of your time and how to make better guesses when that's necessary. I have worked with many students, and typically focus on helping students achieve about 100 point improvements in their math score, from about 600, to 700 or better. You may see other tutors promise more, but they are not the ones taking the test! I know what it takes to help students master the material so that they can be successful on the test.

Discrete Math,

Discrete Math

Discrete math is one of my favorite topics to teach, and I have many satisfied students in person and online to show for it! Set theory, combinatorics, graph theory, propositional logic, mathematical induction, boolean algebra. Fun stuff! I work with a lot of students here at Wyzant and on other platforms, including discrete math and discrete structures for computer science. I have taken (and received an A) in college level discrete math (i.e. math for computer scientists vs. calculus), and regularly teach the subject on Wyzant and other services, including college courses using textbooks by Epp and by Rosen.

Excellent Tutor!

Doug is the perfect tutor. Period. He has been tutoring our son for the past two years in high-school advanced Math and Physics and the difference we have seen is amazing. Our son is now consistently getting A’s and it has increased his confidence in these subjects dramatically. Doug is super clear in his explanations and will find alternative ways to explain difficult topics. He is patient and thorough. He also gives plenty of practice problems to reinforce the learning. If a topic requires additional research, he is great about following up to ensure that he has provided the correct and complete explanation. Doug is also a true professional - punctual and responsive in all communications. It makes it easy for our son and for us to work with him. We can’t thank Doug enough for the impact he has had in helping our son stay at the top of his class in two very tough subjects. Needless to say, we are planning to continue with him through the rest of high school.

Very patient and knowledgeable!!

Over the course of the pandemic my twin boys have taken an unintended gap year from college courses.... meaning they have done very little to keep their brains sharp, especially in the area of math. Doug has already in one session helped them dust off their skills and we will continue to book with him going forward!

Knowledgeable AP Physics tutor

Patient and helpful in assisting my son with prep for the AP Physics 1 test. Also helpful in covering ground that was missed during virtual schooling. Recommend this tutor to anyone needing help with Physics.

Sally, 11 lessons with Doug

Was very less helpful before the AP Physics C exam

Scheduled a lesson on Sunday to clarify few doubts my daughter Anisha had prior to the exam. He joined the lesson saying exactly the lesson needs be concluded in 60 minutes. Halfway through we had a technical issue in our digital pen and my daughter told that she needed to fix the pen and he again mentioned he needs to leave in exactly the scheduled time. The lesson was very shallow in terms of calculations and answers he went to mention it's fine to leave at this point. Next when my daughter said could you pls. send the MCQs you covered he easily mentioned that he will send later. Exam was Monday and he was so not helpful. Later on sent me a message he complaint about me to the tutoring company.

Tutor responded:

The client had agreed to the scheduled one hour session, was happy during the session and even requested a session extension at 47 minutes into our scheduled hour. When I couldn't extend the session due to a previously scheduled session following, she was quite upset and left negative feedback for that reason.

AP Physics taught the right way

Doug has been working with my son Sam (a senior in HS) and after only 2 lessons has made a huge difference in Sam's understanding. Sam says Doug does a very thorough and good job teaching, and has really taken the time to answer all his questions. Sam says that at the end of a tutoring session with Doug, he really feels he completely understands a concept, and feels more confident about approaching the next physics class and the net new concept. Thanks, Doug!

The best tutor I've ever had

Before I started tutoring with Doug, I was struggling very badly in Calculus BC. I had gotten a C on the first semester final exam and ended up with a much lower grade than I wanted. However, it is safe to say that Doug is one of the best tutors I've ever had, as he helped me tremendously throughout my second semester and helped me get an A in the class and on the final. I 100% recommend him as a tutor for calculus!

Dhillon, 14 lessons with Doug

Great tutor

Happy to have found a knowledgeable and patient tutor. He is to the point and communicates the material well and in a systematic way. looking forward to future lessons with him.

great teacher

Doug is great teacher, very insightful. His teaching style gave me great insight and understanding and he is teaching but in a very conversational way... High recommend

Chaz, 2 lessons with Doug

detailed, thorough, patient tutor

Doug helped my son prepare for his AP Calculus BC class and exam. He found interesting and useful practice problems, and explained concepts thoroughly. He was well-prepared, helpful, and kind.

Audrey, 1 lesson with Doug

AP Physics

knowledgable, patient, experienced. Two sessions so far. First session, Doug explained the concepts. Second session, he taught me how to tackle homework problems. Both sessions were really good. I will schedule more sessions with Doug.
