Organic chemistry, taught by someone who teaches it.
I’m a Yale chemistry PhD who has taught Organic Chemistry as a college professor. I help undergraduates understand the material and walk into exams ready.

5.0 average from 153 tutoring ratings, and top marks in my classroom evaluations.
I almost regret working with Vincent because no other tutor is nearly as good as he is. He cares enough to go through your textbook to understand exactly what you’re doing, is patient, knows his stuff inside and out, and always somehow knows what things are commonly tested. I got an A both semesters, when the average in my class was a 75, and a large part of that is due to weekly meetings with Vincent.
His clear explanations made a huge difference in my learning. After just a couple of sessions with him, my exam score went up by 10%! He was patient and always made sure I truly understood the material before moving on.
Despite having technical difficulties with my computer, he patiently worked with me and even stayed longer to make sure I didn’t miss anything. He made complex Organic Chemistry topics easy to grasp.
He has a very deep understanding of Organic Chemistry, and is patient and compassionate with explaining the concepts. Would highly recommend.

Revolutionized my relationship with chemistry/science. Never have I felt so empowered to tackle a subject. With Vincent, there is no such thing as a silly question.
At the start of the semester, I was very confused by organic chemistry, but attending Vincent’s office hours made a huge difference. He provided helpful resources, like specific practice problems and textbook pages, and explained difficult concepts clearly and patiently. I now genuinely enjoy organic chemistry, and his support is a big reason why!
He never makes anyone feel shame for not understanding something or being behind on content. He has a way of teaching and explaining concepts that make you understand it and helps us extend this into practice problems.
True mastery of not only the content, but different ways to explain complex concepts in a way that makes orgo seem almost intuitive.
Vincent worked really hard to make sure his students understood the content. … It is not surprising that his section would constantly run out of chairs as students from other sections decided to join his.
He would give us his tips for how he learned that topic when he was learning it for the first time. … He goes through his thought process for the problems, which is helpful for my understanding of how to go about solving similar problems.
I wasn’t assigned to his section; however, I would rearrange my schedule to attend his classes. … Thank you for making organic chemistry enjoyable!
He organized the material in a clear and concise way, filling in learning gaps that developed during the lecture. Vincent was always available to answer questions and responded to emails very quickly. Altogether, he has been the best teaching fellow I have ever had the pleasure of learning under.
His discussion sections were informative and clarified everything that we had learned in class. He made slideshows and went over each individual reaction and concept to make sure everything was clear. … Vincent is really the one who cemented my learning in this class.
Vincent is the reason I passed Orgo. He’s patient, an incredibly skilled teacher, and understands the material thoroughly.
I LOVE VINCENT 11/10. GIVE HIM THE KEYS TO THE CITY.
Vincent is the only thing that got me through 2 semesters of orgo somewhat alive. He has a great ability to create understanding in really intellectually challenging topics. Vincent, you should be a professor!
Everything he explains makes perfect sense. … He is always looking for ways to make the course feel a bit lighter given that there is just so much content, and he always caters his sections to what we are struggling with.
Organic chemistry II material is certainly dense, but Vincent makes weekly slideshows to summarize our learning and even comprehensive reaction lists to make it a lot easier. He also provides us with resources for learning, such as extra practice problems with solutions.
His belief in students to learn is amazing, and he teaches these often difficult, conceptual topics in such a digestible, understandable way.
His explanations cut through the common disconnect usually with the material. He is so kind, so passionate, just so awesome. He motivated you to always show up and try your best.
From my University of New Haven Orgo 2 classes

I liked how thoroughly Vincent explained everything and how he explained things and communicated in a way that was on our level as students. I never felt like I was being talked down to, or viewed as less than for not understanding.
Definitely take this course with Vincent. I truly understand organic chemistry and it is my favorite class now, and I came into this class hating organic chemistry and not understanding it at all.
Vincent always made sure we understood the material fully before moving on. … He gave many practice problems that matched the level of difficulty that was seen on the exams. Exams were difficult, but fair. I had a good understanding of what the exams would be like before I took them, so I was able to prepare well.
Professor Chang has probably been the best teacher I’ve had during my time at this university. … He never made me feel bad for being confused; instead he would provide support and alternative methods for learning.
I loved the way that he takes the time to think about the way that the students would learn the content, and then makes sure to format it that way. It makes learning harder concepts easier, and it makes a harder class such as organic chemistry 2 less daunting.
I told him I couldn’t attend his office hours without skipping class due to having classes back-to-back, and he added evening Zoom meetings to give students extra help. Amazing teacher!
Come to class! The lectures are always fun and interactive, and Vincent does a great job of making even the hardest concepts feel simple and manageable.
UNH must go to great lengths to retain this instructor. He is too good at teaching chemistry to lose to another school.
More from tutoring students
Vincent was extremely knowledgeable about topics pertaining to Organic Chemistry. He was able to articulate the information in a manner that was concise and clear. I was able to better understand the key concepts after this session. I plan to have many more!

About Vincent
I earned my B.S. in Chemistry from UC Davis in three years with a 4.0 GPA, then my M.S. and PhD in chemistry at Yale. At Yale I taught Organic Chemistry 1 and 2 as a teaching fellow and was named a Prize Teaching Fellow, one of the highest honors a Yale graduate student can receive. I’ve also taught Organic Chemistry 2 as adjunct faculty at the University of New Haven.
I’ve also worked closely with organic chemistry professors to develop curriculum, worksheets, and practice problems, so I know how exams get written and what tends to be on them.
Tutoring is a real passion of mine. I’d love to help you get the grade you’re aiming for.
