Thomas

Approachable, PhD-Level Tutor for Test Prep, Math, Science, & English

Hi there! I am a former scientist who happens to enjoy English and test preparation in addition to math and science. As a tutor, I am patient and adept at identifying areas in which students may need extra help. My style is informal and approachable, and I relate extremely well to students ranging from elementary-school-age to working adults. The subjects in which I specialize include Test Preparation; Mathematics; General Chemistry; Organic Chemistry; English Writing, Grammar, and literatu...

biochemistry

Biochemistry has come to be known as the chemistry of life (originally, that distinction belonged to Organic Chemistry). When I tutor Biochemistry, I encourage students to move away from acronyms and rote memorization in favor of seeing the common themes and molecular principles that underpin Biochemistry. In this way, I help students build a systematic framework on which to hang the pieces of knowledge that they acquire in class. This approach also helps students both to see the big picture and to strengthen memorization through understanding.

Tom has been tutoring my 20 year-old son in community college chemistry, biology and calculus this semester. He is been a terrific help in keeping him on task and motivated. Tom is professional, prompt and let's the student help determine what areas need focused attention. We needed help in assuring homework was done and in preparing for exams. Tom's involvement has really helped our son keep up with the work and he has been able to explain all subjects. We have used many tutors in the past and Tom is by far the best we have ever seen.


Zeyna A. from Gaithersburg, MD

Tom tutored my high school son. Therefore, I am not well versed on exactly what topics were covered on Friday. Tom was preparing my son for chemistry final next week. He covered most of the review topics. Tom gives priority to the needs of his students. He schedules according to the student's availability even if it is inconvenient time for him. Overall, Tom is a great chemistry tutor, with a big heart.


Michelle J. from Washington, DC

Thomas is punctual for every session and he is very knowledgeable about the lesson he's tutoring. My son has learned a lot working with Thomas over the last several months.


Laura B. from Garrett Park, MD

Thomas is very patient and knowledgeable. My son thought he explained chemistry concepts clearly. He was always on time and reliable.


Joan G. from Potomac, MD

He is a good tutor. We were unprepared for the session and he still moved forward like a true professional. I would highly recommend this person as a math tutor.


Zeena A. from Rockville, MD

Tom tutored me through most of Organic Chemistry I and started me on Organic chemistry II. Tom is great at explaining chemistry and is always willing to try to accommodate my hectic schedule. He was able to try different methods of teaching when 1 didn't work (drawing out the diagrams, listing mechanisms, and repetition). He went out of his way and did the homework with me and handed me the notes he took with me (considering mine weren't legible half the time). Over the months that he has tutored me, I have learned that Tom is committed not only to my success in organic chemistry, but also to my successfully reaching my long-term goal of becoming a doctor. I would recommend Tom to anyone looking for a smart, patient, and caring tutor. He is also very easy to communicate with and will travel.


Kivanc S. from Ashburn, VA

Tom's proofreading and basic editing greatly helped the readability of my PhD dissertation in the field of engineering and science. Fast, accurate, and very professional service. I would confidently recommend Tom to anyone who needs quality in his or her thesis.


JOCELYN D. from Germantown, MD

Thomas teach me Math- Algebra. He is very knowledgeable, his method of solving problems is easy to understand, easy to remember and simpler to execute. I am very thankful for everything I learned and will continue to learn from him. I look forward to advance to Calculus and Chemistry.


Molly C. from Washington, DC

Tom helped me get a better sense of what was happening at a fundamental, molecular level that I could not visualize on my own with images in the textbook. My only wish is that I had had more time to cover more ground in our hour. He was very clear and I really appreciate his help, especially on such last-minute notice!


Frank C. from Gaithersburg, MD

Thomas tutored me in Organic Chemistry. He was both comprehensive and detailed in explaining the concepts and mechanisms to me.


Tonjua G. from Bowie, MD

Went over how to construct and ICE table from here experimental data for the oxidation of ethanol by NAD+ to acetaldehyde as catalyzed by alcohol dehydrogenase. We talked about how to calculate the equilibrium concentration of NADH from absorbance data, and how to calculate the equilibrium concentrations of the reactants and acetaldehyde.


Karina L. from Washington, DC

Very helpful and able to provide multiple examples concerning a specific topic. He has helped me understand topics and mechanisms rather than trying to memorize.


Donna G. from Washington, DC

Thomas tutored my grandson in Algebra, my grandson is very shy, but he felt comfortable working with Thomas. He would like to continue working with him.


Lilli S. from Greensburg, PA

Tom really helped me out with concepts I didn't understand, and he gave me lots of confidence for my exams. His methods are really effective, and he is very encouraging!


Helen F. from Virginia Beach, VA

Tom helped me better comprehend some very complex and multi-faceted biochemistry equations/problems. The logic he clarified will aid anyone with difficulty around Kinetics, Thermodynamics, Energetics, and Equilibrium. If you are contemplating hiring a tutor for that extra expertise to help get you over the hump, I assure you, you will be glad you enlisted his help! Good luck!


Sharon C. from Gaithersburg, MD

Thomas spend time getting to know my two boys and spoke to them about interesting facts regarding the English language. They found him to be very interesting and very patient. They're looking forward to the next lesson!


Kelly L. from Rockville, MD

My son was struggling with HS Geometry and he felt as if the fog was clear after his first session with Thomas. He told he really enjoyed his method and said he made it interesting, understandable, and fun! This is truly a remarkable compliment for Thomas coming from a teen who doesn't love school. Can't recommend him highly enough. Thanks!


Denise P. from Germantown, MD

Thomas helped me with the math section of the SAT. He helped me understand the concepts of some problems and also different ways to approach different problems. We also reviewed all the sections that would be on the SAT.


Kathleen S. from Chevy Chase, MD

Thomas reviewed Algebra 2 problems with my son, who said that he understood the material better than when his teacher explained it. That is proof of a successful lesson and money well spent.


Lydia S. from Washington, DC

Tom helped to substantially raise my son's SAT Critical Reading and Writing scores. He was very knowledgeable, reliable, responsive and extremely effective. My son enjoyed working with him very much - we could not have asked for a better tutor!


Dan O. from Rockville, MD

Thomas and my son reviewed the different types of math problems on the ACT. The session went very well and we will continue to work with Tom over the winter.


Walter L. from Silver Spring, MD

My son transferred to a physics course several weeks after school started. Thomas helped him prepare for his first test covering material that he missed. Still waiting for the results of the test but my son seemed to understand the material after his session and appeared confident going into the exam.


Lydia O. from Germantown, MD

Thomas helped me to begin reviewing for the vocabulary portion of the SAT's. He was very patient and would thoroughly go over the parts I didn't understand.


Beth M. from Riverdale, MD

Thomas was very helpful in preparing for a chemistry test. I understood everything after we met and was even able to help a couple friends in class with what Thomas went over with me. I will definitely meet with him again for both chemistry and calculus.


Roslyn W. from Bethesda, MD

My son was very happy to work with Thomas. He said he learned a lot and that Thomas made it easy to understand complex algebraic problems. He was also excited to see how cool working on really complex advanced problems could be. Great job


Zahi M. from Gaithersburg, MD

Thomas's responsibility and accountability come along with his knowledge and expertise that exceed my expectation to meet my daughter's need.


Bersabeh Z. from Gaithersburg, MD

I was studying to take the SAT a second time and started tutoring with Tom. He helped me go from an 1840 to a 2060. I focused on math the most and it went from a 580 to a 700. I'm very pleased with my score results. I'm sure I would have scored much higher if I did not have a lot of school work on my plate as well. Great tutor!


John V. from Rockville, MD

Tom was able to quickly assess my son's abilities and provide guidance in pre calculus over a two week period of time such that my son was successful on his math placement test at UMD.


Jack F. from Gaithersburg, MD

My son is struggling with some of the concepts in Honors Chemistry. Thomas went over Jack's notes and was able to help him gain a better understanding and begin to give him some confidence back.


Indira K. from Potomac, MD

Mr. Thomas C is very knowledgeable in Chemistry. He tutored my daughters in AP Chemistry. As a tutor he was very patient, has excellent command of the subject and was able to help my daughters through areas they needed additional help with. They found the session with him to be helpful.


Mattia A. from Plano, TX

Tom was an incredible organic chemistry tutor. I found him the second semester of organic chemistry. Organic chemistry had been a breeze for me the first semester but it unexpectedly ramped up for the second semester and I went from getting A's on my test to having my first B, even though I was studying and participating in class the same way I had the first semester. After getting Tom, my grades leapt from B's to A's by the end of the semester. Tom was able to patiently walk me through synthesis problems and point out what I was doing incorrectly. He helped me figure out my weak spots in organic chemistry and got me from the path to memorizing steps to understanding how to use the tools I was taught in organic chemistry to see the bigger picture of the problems. I was able to maintain A's in a very difficult class thanks to Tom.
