About Sean

I've taught college level Chemistry and Organic Chemistry at the Community Colleges since 1998. You can go directly to and type my name for more reviews on my teaching abilities. My expertise is in developing entire courses and designing labs for both Organic and General Chemistry. My tutoring experience started back in 1994 teaching both SAT and GRE study techniques. Because I understand how all disciplines are truly integrated I can teach all High School and College level science and math courses.

I received my BS in Biology from the University of California, San Diego and my Masters in Chemistry from San Diego State University. While at San Diego State, I won the graduate teaching assistant award for the subjects General Chemistry and upper division Biochemistry.

Students need to know that these subjects can be mastered by learning some key concepts and how to apply them. I can simplify difficult material and explain it in terms that anyone can understand. My excellent communication skills allow me to present information quickly and efficiently, so as not to waste your or my time. Because I have a degree in both Biology and Chemistry, it's very easy for me to show students the relevance of what they are learning and how all subjects are truly related. I love to teach and that enthusiasm is contagious and typically rubs off on my students. I look forward to working with you and helping you succeed in every course you take!

Cancellation Policy:
I have many commitments and need 24 hour advanced notice for a canceled lesson; otherwise, you will be charged my rate. Cancellations must be done via text, and or phone. DO NOT SEND AN EMAIL to cancel a lesson, because I may be working with students and do not have access to the internet. Text is the number one choice, voicemail is second.

"Awesome tutor"

- Ross, San Diego, CA on 2/25/13
Sean replied on 2/25/2013

Thanks Ross. It was really easy to show you how to solve those stoichiometry problems. You have a solid foundation. With those additional rules and tricks I provided, you're well on your way to solving problems involving quantitative analysis of reactions!

"Awesome tutor"

Sean replied on 2/21/2013

Lisa, you'll do more than just pass the class. You're going to Ace it!

"Wonderful tutor!"

- Kerri, San Diego, CA on 9/25/12
Sean replied on 9/26/2012

Thanks Kerri. I enjoy providing supplementary material for your Organic Chemistry course. Your course is rigorous, but I see that you're catching on. I look forward to our continued sessions!

"Jumps Right In!"

- Cindy, San Diego, CA on 9/2/12
Sean replied on 9/4/2012

It's been a pleasure working with Joe. He's an intelligent hard working student who's prepared for his first year in college.

"Amazing Instructor!"

- David, San Diego, CA on 5/29/12
Sean replied on 5/29/2012

David, It was a pleasure and I'd be more than happy to help you next semester with General Chemistry!

Approved subjects are in bold.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

Algebra 1

Topics I can help with include, but are not limited to: simplifying algebraic expressions involving polynomials and rational terms; factoring; solving linear equations; solving quadratic equations using factoring; analyzing graphs of linear equations; and solving applied problems.

Algebra 2

Topics I can help with include, but are not limited to: radicals, exponents, rational expressions, concepts of relations and functions, exponential and logarithmic functions, linear and quadratic functions, and the solutions of equations from these topics.


I can help students with the following topics, but not limited to: the process of scientific inquiry, the structure and function of life, the biochemistry of biomolecules, metabolism and manipulation of energy by plants and animals, cell division, classical and molecular genetics, development, and the evolution and adaptation of living organisms.


Students will learn to analyze and interpret the periodic table to predict and explain the element’s physical and chemical properties, based on the concepts of atomic structure, electron configurations and periodic properties.

Students will learn to construct the Lewis structure of a given molecule or polyatomic ion that obeys the octet rule and use the Lewis structure to predict the number and types of bonds (single, double and triple) it has and it’s geometry based on the principles of covalent bonding and valence shell electron pair repulsion theory (VSEPR).

Students will learn to analyze a given chemical reaction, including the amounts of reactants to write the balanced equation and to calculate the theoretical yield of the products, based on the concepts of molar mass and stoichiometery.


I can assist both the young enthusiast and/or mature learner. I have experience in showing students all the basic moves for each piece, basic strategies including castling and passing pawns, and overall positioning of pieces to put opponents in check or checkmate!


Topics I can help with include, but are not limited to: lines, angle postulates, triangles including the special right triangle ratios, quadralaterals, circles, polygons, postulates, and theorems.


I am capable of discussing both Anabolic and Catabolic reactions involved in metabolism. I have a strong grasp of the biochemistry seen in the digestion of the four macromolecules and how it ties into cellular respiration. I also can easily teach the difference between the dietic calorie and calorie and show their different calculations.

Organic Chemistry

I can help students with basic nomenclature, stereoisomers, nucleophilic substitution, electrophilic addition, radical mechanisms and other synthesis reactions. I have taught, created, and designed curriculum for college level Organic Chemistry. I can easily implement background information of lab techniques such as melting point, boiling point, simple distillation, fractional distillation, vacuum distillation, steam distillation, recrystalization, acid-base extraction, chromatography, and spectral analysis (Infrared, Nuclear Magnetic Resonance, Mass Spectroscopy, and Gas Chromatography)into tutoring and discuss the relevance of each technique and the importance for synthesis. Once the techniques are understood and students know when to use them, then the mechanisms can be better understood.


I can help students with the following topics: operations on positive and negative numbers; fractions, decimals, and percents; perimeters, areas, and volumes of geometric figures; fundamental algebraic concepts; square roots; and applications.


Topics I can help with include, but are not limited to: linear, quadratic, polynomial, rational, trigonometric, exponential, and logarithmic functions; systems of equations and inequalities; and conics.


Topics I can help with include, but are not limited to: solutions of applied problems involving right triangles; graphs of trigonometric functions, including period changes, amplitude changes, and phase shifts; trigonometric identities; trigonometric equation solving; and evaluation of inverse trigonometric functions.

Great Tutor! — Sean knows his stuff and he's very enthusiastic about teaching it. I have been seeing Sean for organic chemistry. The material is hard but he makes it easy to understand. During our sessions we go over material that was covered in class and even get ahead and preview the next topic that will be discussed for my upcoming lecture, which makes it easier for me to follow along and understand my instru ...
