I am a recently retired university professor with 37 years' teaching and research experience in organic and bio-organic chemistry at two major U. S. State universities. During the past 18 years I have served as an MCAT content contributor by providing "units" (passages + questions based on passage content) to the Association of American Medical Colleges (AAMC), the agency that produces and administers MCAT. I currently tutor students worldwide by using interactive Skype and Google Hangouts with screen sharing. The screen sharing feature permits chemical structures, formulas and reaction mechanisms to be drawn onscreen in real time during tutorial sessions. All visual materials produced in this manner are saved as jpg files and sent to students as email attachments at the conclusion of each tutorial session. In addition to one-on-one tutoring, Students are provided with study and review materials, practice problems and sample exam questions that I know from experience are likely to appear on midterm and final examinations.

Dr. Alan was super helpful and patient. He knows organic chemistry very well and can explain the material in a way that anyone can understand.

I was getting really discouraged with MCAT studying and practice, so I decided to contact Dr. Alan.
He is extremely knowledgeable in general chemistry, organic chemistry and biochem. He also knows how the MCAT exam is designed and written. He is a great source of information.
Furthermore, he prioritizes making sure his students understand why certain answers are wrong or right. He is very detail oriented and really wants his students to understand the material.
Dr. Alan tutored me online, and shared his screen with me while working out chemical reactions and problems. He then saved all of that work and emailed it to me, so I could refer to it later.
Dr. Alan definitely tries to provide his students with the resources to succeed. He sends his students extra practice as well as power points and tutorials on information that he knows is tested on the MCAT.
I am very glad I contacted Dr. Alan, because he is a very dedicated caring teacher, and he really wants his students to do well. I would recommend him to anyone who needs some guidance on the MCAT!

I took tutorials on general chemistry with Dr. Alan for one term. He always went extra miles to make sure that I was prepared for my tutorial sessions by sending me enrichment materials on topics that were covered in my class beforehand. He accommodated my learning style and was able to provide supplemental lectures as I requested, which I appreciate tremendously. He was also always very prompt in responding to my emails. He doesn't always provide direct answers when you ask questions, but provides guidance in a way that makes you think -I believe this is essential in learning. I would recommend tutorials with Dr. Alan if you are keen on learning and truly want to comprehend your subjects of interest well.

As a non-traditional student I was struggling with Gen Chem 2 early in the semester because I didn't have the fresh skillset my peers possessed from only being out of high school chemistry for a year or less. Dr. Alan helped simplify complex concepts which brought me up to speed and made sense of the fray, allowing me to go from a 70 at the the beginning of the semester to a high A by the end of the semester.

Dr. M is the best! I decided to take organic chemistry this summer and he's been with me every step of the way! He is very patient with me and I don't feel discouraged when I don't get the right answer (which I've found to be the case with my professor). He goes above and beyond by giving me practice problems ahead of time and by sending me copies of the notes we make during our meetings so I don't have to frantically scribble down notes. I have a much deeper understanding of organic chemistry thanks to Dr. M! If you're looking for someone who can help you with organic chemistry, look no further!

Dr. Alan was an incredible tutor- he was diligent in setting up practice problems for my MCAT review. His extraordinary understanding of the material made it easier for me to understand - he took the extra time to explain problems and break down concepts. He was thorough - provided additional study materials and made the process enjoyable. I could not recommend him more for anyone wanting help in biochemistry, chemistry or MCAT prep.
