About Ryan

Hi folks! My name is Ryan. I'm a full-time tutor and former physicist/astronomer with an excellent background in math, science, economics, and English composition. I have considerable teaching and tutoring experience at high school and college undergraduate levels. My primary subjects are physics, math (from Algebra 1 to Calc II), English writing, and SAT/ACT test prep. I also do some chemistry and economics.

Availability Update: I will be out of town from September 5-21.

I've recently tutored students from the following schools:

High Schools:

Brea Olinda
Copenhagen International School (Copenhagen, Denmark)
Diamond Bar
El Modena
Fairmont Preparatory Academy
Glen A. Wilson
La Canada Flintridge
La Habra
La Puente
La Serna
Los Altos
Oxford Academy (Cypress)
San Marino
Sunny Hills
Walworth Barbour American International School (Even Yehuda, Israel)
Whittier Christian
Yorba Linda


Cal State Long Beach
Cerritos Community
Fullerton Community
Harvey Mudd
Johns Hopkins
Mt. San Antonio Community
UC Irvine

I've also worked with homeschool students and adults not affiliated with a college seeking professional certification/grad school admission.

I'm a National AP Scholar, National Merit Scholar, and National Science Foundation Graduate Research Fellow. I got a 1580 on my SAT and a 1520 on my GRE. I took and passed 10 AP tests. I received 5s in Biology, Physics B, Calculus AB, Statistics, English Literature, English Language, US History, and Macroeconomics, and received a 4 in Microeconomics and Chemistry (AP classes were not offered in Biology, Chemistry, Macroeconomics, or Microeconomics).

I have a LOT of experience taking standardized tests, and am able to prepare others. There is a subtle difference between teaching students a new subject area and teaching experienced students how to take a test - I have experience and a successful record doing both.

Perhaps most importantly, I've been told I am very empathetic. I am a product of public K-12 education and understand where kids are coming from who attend those schools. I also know that, particularly in math and the hard sciences, much of my work will be confidence building and challenging the negative self-talk about "not being a math person."

I'm also keenly aware that many students haven't been taught/sold the idea that it pays to be organized, and to develop effective study skills. I receive many inquiries from parents who are frustrated because their child is bright, but starting to struggle. Usually this is because the student coasted through earlier coursework without cultivating a combination of work ethic, time management, organizational skills, and a self-awareness about how best he or she learns. It's hard to do this on a short-term basis, but I've had success with some of my long-term students. I'm incredibly proud of my students that make the transition from doing coursework "because it's needed" to "because it's my responsibility" to "because I enjoy it and can see how this will connect to things down the line".

I love what I do! Please feel free to ask if you have any questions. Hope to hear from you soon!

Note: I typically take older students (high school, college, adult).

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.

ACT Reading

I have tutored several students in ACT across all four subjects. My experience has been that students tend to find the English and Reading portions slightly easier than the corresponding sections on the SAT. However, despite its name, the science section tests quick reasoning and data interpretation, not scientific knowledge per se. Most students, even those with a strong science background, experience the most time pressure on that subject.

I've also advised students and parents regarding the different approaches schools take with regard to accepting scores. Many schools superscore the SAT, while most schools do not do that with the ACT.

College Counseling

I have worked with five separate high school students to help them prepare for the college applications process. Together, we generate a schedule and study plan that will improve performance on the required standardized tests. I also provide guidelines as to the content, tone, and structure of the personal statement. Finally, I also provide guidance about the heavier importance most students should place on financial aid, and guide them through this process. I do not discourage scholarship applications, but I manage expectations, and provide guidance about essay content tailored to the specific scholarship.

Public Speaking

I was first introduced to public speaking in 4th grade, when my teacher, sensing an opportunity to break someone of the stereotype of the shy, nerdy kid, required me to deliver multi-page assembly speeches from memory.

I have delivered multiple public outreach talks, technical presentations, and lay sermons at churches.

Study Skills

I have experience generating calendars, schedules, and programs of study for high school and college students. I instruct students on how to read a text, how to take notes, how to create formula sheets for their personal use, how to store information for later use and citation in a paper, and how to organize their answers on a page. As a student, teacher, and tutor, I have learned the art of focusing on the urgent and important (Stephen Covey's method) and prioritizing academic work.


Trigonometry is typically not taught as a standalone subject. It is usually folded into a precalculus/math analysis class taken the year after Algebra 2.

By far, student regularly cite this as the most challenging portion of a precalculus class. It requires a great deal of memorization and an ability to juggle multiple equations/identities.

I usually spend a great deal of time drilling students in the unit circle. We then transition to the basic and intermediate identities. Proving an identity is typically the hardest task. Once students develop their basic knowledge sufficiently, I give them a set of guidelines that provide possible strategies against trig identity problems. Note that the nature of the problems means that there is not a strict hierarchy of superordinate/subordinate rules. Rather, there are a few things that students can try on each problem. I make certain to teach *how* a student can recognize which tools are more likely to work in a given situation.
