My daughter took 16 organic chemistry II classes with Reef this summer, and he did an excellent job tutoring her. She now feels much more confident about her fall semester class. I highly recommend Reef 100%!

After just three classes, I already feel like I have a much better understanding of IUPAC nomenclature and stereochemistry than I did from my university classes. Reef clearly has a strong understanding of organic chemistry and, more importantly, knows how to explain difficult concepts in a clear and understandable way. I’m really glad I started working with him, and I hope to continue working with him next semester as I prepare for the MCAT.

We’ve been very happy with Reef with his teaching. In just a few weeks, my daughter has become much more confident. Reef is proactive, explains concepts clearly, and is always willing to help. Highly recommend!

Our session went very well! Reef was very good at explaining the concepts that I wasn’t 100% sure about. I ended scoring extremely high on my chemistry final!

Thanks to Reef, I raised my DAT scores by 6 points in Organic Chemistry and 5 points in General Chem. His intensive, back-to-back sessions and proven MCQ strategies gave me the edge I needed to walk into the test fully prepared.

I am now a junior at Cornell University, and Reef has been a great help to me in Organic Chemistry I since my freshman year. I will also be working with him again in Fall 2026 for Org Chem 2. He has unique teaching skills, especially when explaining stereochemistry and reaction mechanisms. I highly recommend him to anyone taking chemistry courses.

Reef helped me earn an A+ in Organic Chemistry at the University of Michigan and greatly improved my MCAT Organic Chemistry skills. His unique approach to retrosynthesis and multistep synthesis made difficult concepts easy to understand. He also graduated from a top school, and I highly recommend Reef tutor for Ochem 1, Ochem 2, and MCAT preparation.

Thank you for the emergency session! Really knew how to target the key points quickly before my MCAT. Reef teaches solid OCEHM and GenChem.

Great tutor! I wouldn’t have passed without him.

Reef is an experienced Chem tutor for graduate levels!! I highly recommend him.

I started my last semester with very low scores and wanted to get ahead this semester by getting tutoring to understand the concepts before class so that I will be ahead. Mr. Reef has extensive knowledge in the sciences and has been able to get me ahead of my organic chemistry class. I feel so much more confident in the concepts being applied in class since he explains everything thoroughly, gives you resources to grasp and practice the concepts, and also helps explain some of the homework from my class. He is very attentive, responsible, adaptive to your own schedule, and replies very quickly. Would highly recommend for anyone taking any sort of chemistry class.

Reef’s Organic Chemistry II expertise made a huge difference—his clear explanations and problem-solving strategies finally made everything click. Thanks to his support right before my finals. The Zoom sessions were very helpful.

My mom assigned Reef as a tutor for Ochem 1 in fall 2025. As a freshman, I got a lot of help from him to prepare for the finals. I had A+, and I give full credit to him. I will be taking classes with him until my MCAT. Highly recommended for Ochem 1 and Ochem 2.

Reef is truly a master of organic chemistry and tutoring.

While concepts initially felt foreign, he took the time to comprehensively explain them without overwhelming me and had the patience to answer any follow-up questions no matter the extent!

If you want to not only do well in OCHEM but also more importantly truly understand it - then take Reef!

Reef is a really great AP Chemistry tutor who knows the subject very well and explains things in a way that’s easy to understand. He helped me feel more confident and do better in class and on tests.

I have never felt Zoom classes were so helpful. Reef turned organic chemistry 1 chaos into clarity, earning me a good grade and genuine excitement for OChem 2 next spring! He really remembers two Ochem textbooks, David Klein, and Paula De Bruice. Moreover, thanks for the enormous amounts of practice assignments that boost my confidence to tackle the mechanism problems.

I have known him for only a couple of weeks and he is reliable, responds quickly and provides very hands on one-on-one tutoring. He is able to clarify any conceptual questions I have and provides me with an abundance of practice material that I can practice from, sometimes without me even asking. Highly recommend if anyone is looking for a chemistry tutor!

Reef has been heaven sent. I love his personalized approach to learning. My daughter has gained so much confidence since she started Chemistry & Geometry lessons with Reef. The best part for me is Reef's genuine investment in the success of my daughter.
