About Gary


Bio

I am a college chemistry instructor, synthetic organic chemist, and experienced tutor with a Ph.D. in Chemistry from UC San Diego. For more than a decade, I have taught and mentored hundreds of high school and college students in general chemistry, organic chemistry, and biochemistry. I have also completed more than 1,000 hours of one-on-one tutoring.

I am a college chemistry instructor, synthetic organic chemist, and experienced tutor with a Ph.D. in Chemistry from UC San Diego. For more than a decade, I have taught and mentored hundreds of high school and college students in general chemistry, organic chemistry, and biochemistry. I have also completed more than 1,000 hours of one-on-one tutoring.

Beyond the classroom, I have conducted organic chemistry research in academic and industrial laboratories. This experience helps me connect fundamental concepts to applications in research, healthcare, and laboratory work.

My teaching approach is patient, encouraging, and highly individualized. Chemistry is too often presented as facts and formulas to memorize, but lasting success comes from understanding molecular behavior, recognizing patterns, and reasoning through unfamiliar problems. I emphasize chemical intuition and problem-solving rather than rote memorization or shortcuts.

During each lesson, I break challenging ideas into manageable steps, adapt my explanations to the student, and reinforce concepts through examples and guided practice. I also have extensive experience supporting students who struggle with focus, organization, time management, or feeling overwhelmed by multistep problems. I provide clear structure, check understanding frequently, adjust the pace as needed, and teach practical study strategies that build confidence and independence.

My students describe me as patient, approachable, and deeply invested in their success. My teaching and mentorship have been recognized with a UC San Diego Teaching Excellence Award. Whether a student is rebuilding a shaky foundation, preparing for an exam, or mastering advanced organic chemistry, I meet them where they are while maintaining the rigor needed for genuine improvement.

My goal is not simply to improve exam scores. I want students to become confident, independent problem-solvers who can approach new questions without fear. I look forward to working with you!

Fantastic Tutor

Gary really helped me understand organic chemistry. Before I began tutoring with him, I was really struggling and failing my chemistry class. But after a few lessons things really started to make sense. He explains concepts in a way that make them super easy to understand and grasp. I would highly recommend him to anyone looking for help with organic chem!

Knowledgeable and patient tutor

Gary's teaching is exactly as he represents himself in his description. He is knowledgeable, patient and uses different approaches to teach a concept, particularly when you do not seem to understand. He has a pleasant demeanor that reflects a sincere desire to help you learn. I highly recommend him.

Professional and knowledgeable

I scheduled some lessons with him and he really knows how to explain difficult concepts to students. Orgo is definitely not easy for me, but learning the topics and reviewing material with Gary was truly amazing. I had difficulties grasping the concepts of chirality, conformation, and stereochemistry, but he summarized what I learned from school with clear explanations in only a few lessons.

Tim, 10 lessons with Gary

If you want to learn the concept contact him.

In times of COVID, Gary has helped me immensely with Organic Chemistry. He cares about your learning and he expects you to care too. His teaching style is establishing a solid base and building on this base in order to tackle harder concepts. Look no further.
