I am currently a tenured mathematics professor at a local university, and I have been at this institution since 2001. I have an undergraduate degree in mathematics and a Ph.D. in mathematics. I have been been tutoring mathematics in many situations since I was in high school. I have experience teaching and tutoring mathematics across the curriculum at the college/university, high school, and developmental levels. I also have sev...

Timothy helped my son with his business calculus homework. He had missed several days of school, fell behind and was lost. We sent multiple assignments to Timothy ahead of time. Timothy was prepared for the lesson, taught him the key concepts effectively and efficiently and asked my son questions to make sure he was understanding the material throughout. This was all covered in one lesson. We thought it would take multiple lessons. With Timothy?s instruction, my son was able to complete his homework and got 100%. We will contact Timothy the next time my son needs any math tutoring!

My daughter was so excited after meeting with Timothy. He really helped her understand a topic she wasn't fully getting. She left their tutoring session feeling very confident and told me she really enjoyed working with him and wants to keep working with Timothy when she needs additional support. She took her test and aced it! Highly recommend!

Excellent at explaining and patient. Helped us find the right time to meet. Convenient to meet online. Jumped right in and explained, helping it all make sense.
- Alison R. from Glenview, IL
He helped me better understand concepts in my college differential equations class. He taught me far easier and more efficient methods of solving ODEs. These methods were easy for me to understand because he explained them slowly and thoroughly. He was also patient and went back if needed. Thank you, Timothy!
- Janhvie J. from Fairfax, VA
Timothy is knowledgeable and patient and very nice. He helped me with mathematical biology. I was very happy that he had my textbook. Will definitely use him again if I need help.

Timothy is a great tutor. Patient, helpful and knowledgeable. He did a great job explaining the material. Highly recommend him!
- Michael T. from Wilmette, IL
Tim has been helping with precalculus and AP statistics. He has been great at helping our son understand the content better.
- Gail M. from Cambridge, MA
Timothy had me coached up in just one hour to excel at my business calculus exam! 10/10 recommend!! He was very patient and does an amazing job at twisting the question in a way that it makes much more sense!
- Emma S. from Waxahachie, TX
I was able to understand statistics much better, problems started to make sense and I after a lesson I felt more confident in my ability to solve problems

I am an undergraduate student at the University of Washington. Tim was able to help with my Calculus class even though it included a lot of Biological modeling (it was a course designed specifically for Biologists). He was familiar with my textbook and the material I was going over, whereas other tutors I have had in the past were confused about some of my problems. He is kind and patient and non-judgmental, even if you ask him to explain one thing many times. I would highly recommend Tim for your math needs.

Timothy C. is an expert tutor. I develop empirically validated curriculum for a living and I work with many subject matter experts who don't know diddly about instruction. Timothy knows calculus and how to get it across. If you can get on Timothy's schedule, just do it. He will help you in less time than you thought possible. My son, a strong student, got a first year AP Calculus teacher. The teacher, though well meaning, could not impart the material in a way that made sense. Many strong students struggled. Within a few sessions, my son was on track, understanding the material and renewing his confidence. We're sticking with Timothy C. for the year because he will ensure my son's success. He's a great guy too.

Timothy is teaching Calculus BC to my daughter, who struggled with her homework. Timothy helped her to understand the concepts, and she is delighted with his skillset and teaching methods.
- Imran K. from Woodbridge, VA
My daughter just had a lesson with this tutor and he was just complaining that he had 17 lessons today. He just gave her the answers without teaching her the concepts. He even responded to a question on how to solve a problem by saying "just solving it". Sloppy writing and he was not interest at all in helping out my daughter on solving the problems. Don't recommend this tutor at all.
- Adriana S. from Saint Louis, MO
We covered some new stats concepts and the time spent was super helpful. Timothy is patient and he does a good job clarifying the stats material. Our ongoing sessions are helping me build confidence from week to week.
- Tanya C. from Manakin Sabot, VA
My reluctant mathematician was actually laughing during the lesson while they learned! Tim really made a good connection with them!
- Julie B. from Winnetka, IL
My daughter met with Timothy for 1 tutoring session for college level Calc 2. She had already met some free tutors at her college but they did not know how to solve problems. After one session my daughter felt much clearer about the information she was learning.
- Dayna T. from Marietta, GA
He taught us how to use Geogebra to do geometry, which was exactly what I wanted. A very patient teacher. He has the experience and ability to explain concepts that one can grasp on the first explanation.
- James M. from Phoenix, AZ
Timothy was extremely helpful in going over weekly lessons and breaking down homework problems. He was always happy to answer questions and repeat topics in a different way if they did not initially make sense.
- Emma W. from South Webster, OH
Tim is very clear and patient when teaching. He really helps you understand the topics. We went over several exercises and he had the knowledge and the clarity to explain all problems.
- Alessandro M. from New York, NY
Dr. Comar is an excellent teacher! His knowledge of mathematics is very deep but he is also very wise and caring when helping with personal situations. When explaining a concept and helping you with a problem he does not move on until he is convinced you understand it. I highly recommend him as a tutor.
