Award-Winning Organic Chemistry Tutors
serving Fresno, CA

Zhenrui's premed and electrical engineering coursework at Columbia means he's tackled organic chemistry from both the biological and physical sciences side — thermodynamic versus kinetic control, molecular orbital theory, and the quantitative reasoning behind reaction energetics that pure pre-med students often find unfamiliar. That dual perspective lets him explain why a carbonyl addition proceeds the way it does, not just diagram the arrows.

Reaction mechanisms are the language of organic chemistry, and most students struggle because they try to memorize hundreds of reactions instead of learning the handful of electron-pushing patterns that explain nearly all of them. Nicholas teaches students to read nucleophilicity, leaving group ability, and steric effects as clues that predict outcomes — turning synthesis problems from guesswork into logical puzzles.

Studying cancer cells at the molecular level means Siavash lives inside organic chemistry — reaction mechanisms, functional group transformations, and stereochemistry aren't abstract concepts for him but daily tools. He walks through arrow-pushing and electron movement with the kind of fluency that comes from applying orgo in an active research lab at Cal State Northridge.

Most students dread organic chemistry's reaction mechanisms, but Sarah approaches them as logic puzzles with predictable patterns. Her physics and math training sharpens the way she teaches electron movement, stereochemistry, and retrosynthetic analysis — treating each mechanism as a problem to reason through rather than a sequence to memorize.

I am a graduate of the University of California, Los Angeles. I received my Bachelor of Arts in International Development Studies with a focus on the Middle East and North Africa. I also completed a minor in Public Health during my undergraduate career. Upon my graduation from UCLA in June 2013, I received both Latin Honors (cum laude) and a nomination to the Phi Beta Kappa (P.B.K.) National Society. I have recently been accepted to medical school and plan to attend in August 2014. I have experience teaching in middle school and high school settings abroad in both the Philippines and Honduras. I have also tutored family and friends in the sciences throughout my college career. I am intelligent, articulate, patient, and motivating, which I believe allows me to be a successful tutor. I have extensive experience working with children and am determined to make sure my students not only excel in their classes, but also learn the material well and develop an aptitude for academia. I believe education is the gateway to success and feel committed to help prepare my students for their future. In my spare time, I enjoy reading, traveling, running, and hiking with my dog.

I am a graduate of the University of California at Berkeley with a Bachelors degree in Molecular and Cellular Biology. During my four years of college, I guided K-12 students of the Oakland area in Language Arts and Mathematics and served as a mentor for many high school students. I have also been an undergraduate student instructor for the General Biology lab course offered at U.C. Berkeley, a prerequisite for students wishing to pursue Biology as a major. Since I have a wide range of teaching experiences in both academic subjects and test preparation, I am highly adaptable to different learning styles and cater my teaching methods to meet student needs. Apart from being flexible, I am also very accessible for additional questions or help that is needed. In my spare time, I enjoy baking, exploring my city and watching movies.

Siddharth's biology degree means he first encountered organic chemistry through the lens of biomolecules — amino acid reactivity, lipid structures, and the functional group behavior that drives metabolic pathways. That biological framing gives him a practical way to teach arrow-pushing and reaction classifications, connecting each mechanism to molecules students can visualize rather than treating them as abstract exercises.

Reaction mechanisms in organic chemistry reward the same kind of systematic thinking that drives engineering design: track the electrons, identify the functional groups, and predict what happens next. Lee teaches students to read mechanisms as stories with cause and effect — nucleophile attacks electrophile, leaving group departs — instead of memorizing hundreds of individual reactions. His biomedical background adds context for why specific organic reactions matter in drug design and biochemistry.

As an MD/PhD student at Northwestern doing doctoral research in organic synthesis, Austin lives in the world of reaction design — figuring out which bonds to form, which protecting groups to use, and why one retrosynthetic route beats another. That daily immersion means he teaches mechanisms and stereochemistry with the fluency of someone who actually builds molecules, not just someone who once passed the course.

Studying chemistry at Harvard while preparing for Columbia Medical School means James has worked through organic chemistry from both the academic and pre-med sides — understanding mechanisms deeply enough to satisfy a chemistry major, and efficiently enough to apply them in biochemistry and pharmacology contexts. He's particularly strong at teaching students how to predict reaction outcomes by analyzing charge stability and leaving group trends rather than treating each transformation as a new thing to memorize. Rated 4.9 by students.

Reaction mechanisms are the language of organic chemistry, and most students struggle because they try to memorize arrows instead of understanding electron flow. Abrahim unpacks each mechanism — SN1 vs. SN2, E1 vs. E2, electrophilic aromatic substitution — by starting with nucleophilicity, sterics, and leaving-group ability so the logic drives the arrow-pushing rather than the other way around. His 5.0 rating speaks to how well that approach clicks.

David is earning his PhD in organic chemistry at Northwestern, where he teaches undergraduate orgo labs and recitations and has co-written exam questions for the department. That means he knows exactly which reaction mechanisms, stereochemistry problems, and retrosynthesis challenges professors test — and how to break them down so the logic clicks. Rated 5.0 by students, he ties each mechanism to real-world applications that make the material stick.

Currently majoring in chemistry at MIT, Nicholas is immersed in the reaction logic and electron-pushing that organic chemistry demands — and he's learning it at a program known for its rigorous mechanistic approach. He breaks down topics like nucleophilic additions and stereochemical outcomes by connecting them to the underlying thermodynamic and kinetic reasoning, making unfamiliar transformations feel predictable rather than random. Rated 5.0 by students.

Reaction mechanisms are the language of organic chemistry, and David treats them that way — once a student can read electron flow through curved arrows, predicting products for substitution, elimination, and addition reactions becomes systematic rather than overwhelming. His Yale neuroscience training required two semesters of organic chemistry, and he still uses those fundamentals daily in his bioethics graduate work.

Most students dread organic chemistry because it feels like a new language, but the logic underneath reaction mechanisms is surprisingly consistent once someone lays it out clearly. Ade approaches each reaction type — substitution, elimination, addition — by teaching students to read electron movement and predict products rather than memorize hundreds of individual reactions.

Reaction mechanisms in organic chemistry are less about memorizing hundreds of arrows and more about recognizing a handful of recurring patterns — nucleophilic attacks, leaving group stability, and electron density shifts. Aidan studied organic chemistry as part of Notre Dame's premed track and teaches students to predict products by understanding why electrons move, not just where.

Reaction mechanisms in organic chemistry demand the same kind of pattern recognition Seong uses in her neuroscience coursework at Northwestern — tracking electron movement, predicting intermediates, and understanding why one pathway dominates over another. She unpacks arrow-pushing notation by tying each step to underlying principles of nucleophilicity and sterics, so students can reason through unfamiliar reactions on exams instead of relying on rote memorization.

Working in a cancer biology research lab means Yasheen encounters the organic chemistry behind drug design and molecular signaling every day — not as textbook problems, but as real questions about how functional groups determine a molecule's behavior in living systems. She connects that bench-level intuition to the arrow-pushing, stereochemistry, and carbonyl reactivity students need to master in their orgo courses. Rated 5.0 by students.
