About John

Hi! I am a certified biology teacher and have taught all levels of high school biology, as well as marine science, and have done SAT and GRE test prep for Kaplan. I have years of experience working with students in a variety of subjects and I love to help students improve. I have done graduate-level research in Boston and in Auckland, New Zealand, and am always trying to improve my own content knowledge. I can personalize your education plan to make sure it is effective for you and help you reach your academic goals.

I am familiar with using educational technology and can incorporate it into lessons to make learning easier and more permanent. Subject or test prep shouldn't be about memorizing terms without context or finding shortcuts, but about real improvement and a passion for the subject. I will challenge you and do everything I can to make tutoring an experience that is both enjoyable and rewarding.

I will help you improve your SAT score, no matter where you start out. Using some of the techniques that helped me score highly on the SAT and receive a perfect 800 score on the math section of the GRE (Graduate Record Examination- like the SAT but for college students pursuing graduate school), students will learn to improve their number skills and spatial reasoning. I previously tutored students in preparation for the SAT and GRE for Kaplan, and am familiar with the layout and question types found on both tests. I can help you master the abilities and techniques needed to succeed.

I have taught four years at the high school level and in that time, I have taught grade-level, honors, and AP biology, as well as a class in marine science. Additionally, I have done graduate-level cognitive research on pigeons and New Caledonian crows, giving me a solid background in research techniques and the abilities required to succeed in high level science. If you are looking to score well on the AP biology test, I have experience teaching the course itself (most tutors do not) and had many students score a 4 or higher on the test.

Please feel free to get in touch with me. I generally meet students at libraries or other public places, but if you have specific location requests, I can often accommodate them. I look forward to hearing from you and helping you achieve your academic goals!

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 coached youth basketball (boys: ages 9-12) and been an assistant coach for older girls' teams. I can develop your player's skills and confidence, and make basketball a fun endeavor for them. I use a variety of drills to develop the fundamentals and can teach your child the proper form for shooting, playing defense, etc. I have seen players vastly improve by following these methods.


I am certified high school biology teacher with four years teaching experience. I have instructed students in grade-level, honors, and AP biology, and seen them succeed in all three levels. My undergraduate degree is in biology and I have a Master's of Arts in Teaching with an emphasis in biology. Using a breadth of content knowledge, I can provide examples of many biological concepts to relate these ideas to students more concretely.


I previously tutored for Kaplan in GRE preparation and scored a 1500 on the test itself (700 verbal, 800 quantitative). I have helped multiple students improve their GRE scores and can give students the tools they need to succeed on the test.

SAT Math

I have tutored many students in SAT prep over the years and have helped them improve their scores significantly. As a high school teacher, I know how to work with teenagers and can provide a variety of instructional techniques to help students succeed on the test.
