About Gregory

I am a certified teacher who now works exclusively as a private tutor. I have taught Biology, Chemistry, and Physics (including Honors and A.P. classes). I have been working professionally as a teacher and tutor for over ten years.

In the past year I have tutored students from the following schools and I am familiar with these schools' standards and curricula (partial list):

Harvard-Westlake, Brentwood, Notre Dame, Crespi, Wildwood, Palisades Charter H.S., Windward, Marlborough, Milken Community H.S., New Roads H.S., Campbell Hall, Sierra Canyon, Beverly Hills H.S., Arcadia H.S., Santa Monica H.S., South Bay private school, Saint Paul the Apostle School, Mira Costa H.S., Saint Monica Catholic High School, USC (Bio. & Chem.), and Santa Monica College (Bio. & Chem.).

I’ve worked with a variety of students of all ages, learning abilities, and backgrounds. I am patient and understanding, especially with struggling students. Former students describe me as knowledgeable, understandable, and funny. I believe a sense of humor is a valuable tool when tackling tough subject areas.

I have helped students prepare for many standardized tests including the ISEE, HSPT, ACT, PSAT, SAT (math, reading, & writing), SAT Subject Tests (Bio E/M & Chem), as well as AP Tests (Biology, Chemistry, and Environmental Science-APES), and the GED.

Excellent references and resume available.

“Greg is a gifted teacher with an exceptional ability to connect with people and particularly, kids. He has that unusual combination of absolute fluency with the subject matter, ability to customize the teaching approach to the individual student's needs, and overlaying it all, on a human level he is a great support and ally for his students. Other parents I have spoken with whose kids have worked with Greg have had an equally positive experience. I feel very fortunate to have found him.”

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.


I have worked with many students that have attention problems. I can help identify critical elements for school success, effective behavioral strategies, and how to help these students stay organized. I can be a valuable resource for parents, teachers, and ADHD students alike.


Including AP Biology & AP Environmental Science.


I have helped many students prepare smarter and score higher on the Catholic High School Entrance Exams. That's because I can provide personalized COOP, HSPT and TACHS prep experience designed to meet your specific needs and goals. I also provide information on test format, question types, and scoring rules, along with expert tips that guide students through verbal and quantitative (math) exercises.

Elementary (K-6th)

I am a certified teacher and have tutored elementary students for the past ten years one-on-one as well as in group settings. Strong reading, writing, and math skills are the foundation for future academic success. I have taught every aspect of reading from sound and word recognition through the skills necessary to read great literature. I am comfortable teaching writing - from basic spelling, vocabulary, and sentence construction to research papers and creative fiction. I have an extensive background in mathematics and science rarely found in elementary teachers. Beyond memorizing facts, I help children to see how their lessons apply to real life.
I work with parents so life-long learning habits are established.

I have tutored elementary students from the following Los Angeles area schools: John Thomas Dye School, Brentwood School, Crossroads, St. Paul the Apostle, New Roads School, Westside Neighborhood School, and Sierra Canyon School.


The Independent School Entrance Exam (ISEE - Grades 4-12) provides secure, flexible testing, accurate scoring, clear reporting and responsive service. I've helped many students over the years prepare for the ISEE and reach their goals for admission to top private schools. I am also familiar with many of the retail products that students will have to use to prepare for the ISEE. My experience teaching SAT, ACT, SHSAT, and other standardized tests, along with my 10+ years of teaching, has well-prepared me to coach anyone to ISEE success.


As both a tutor and certified teacher, I have helped many students successfully prepare for the PSAT. It's a standardized test that provides firsthand practice for the SAT®. It also gives you a chance to enter NMSC scholarship programs and gain access to college and career planning tools.
The PSAT/NMSQT measures:
• Critical reading skills
Math problem-solving skills
Writing skills

The most common reasons for taking the PSAT/NMSQT are to:
• Receive feedback on your strengths and weaknesses on skills necessary for college study. You can then focus your preparation on those areas that could most benefit from additional study or practice.
• See how your performance on an admissions test might compare with that of others applying to college.
• Enter the competition for scholarships from NMSC (grade 11).
• Help prepare for the SAT. You can become familiar with the kinds of questions and the exact directions you will see on the SAT.

Study Skills

I am a certified teacher with several years of classroom experience (including Honors & Advanced Placement courses). I have been tutoring privately for over ten years and have helped hundreds of students with their study skills.

I teach students how to become more organized, to plan ahead, and to use their study time appropriately. I encourage students to use an assignment book and track their homework due dates, test dates, and plan accordingly. Other study skills that students learn while working with me include goal-setting, prioritizing, and predicting possible test questions.
