About this tutor

I have been tutoring since 2012. Over this time, I have tutored over 70 students for, on average, about two years each as a private tutor. While in college, I also worked as a TA (Environmental Chemistry, Genetics and Cellular Biology, General Chemistry, and Organic Chemistry) and as a Quantitative Skills Fellow, holding each position for two years. In these positions, I provided academic support to over 200 students.

I look for ways to best cater to the students' learning styles and academic needs, while also developing and reinforcing habits that will facilitate long-term academic success.

I enjoy working with students and learning better ways to learn together. Whether it is a challenging course or a course that requires a lot of busywork, we always find ways to succeed academically and get ready for future coursework. I work hard to make sure that my students understand the material in-depth and can comfortably excel in tests without worry or anxiety. I have experience working with children as young as 8 and adults as old as 28. Every student brings a unique perspective to my work, which I really appreciate. I also have worked with students with learning disabilities, which has allowed me to get experience working with students who learn differently.

    Carlos has been just fantastic! We originally hired him to help my daughter (9th grader) with the SSAT so that she could transfer to a private school. My daughter's improvement was unbelievable, from a fairly low score to an almost perfect score in two sections. I truly do not know how, but Carlos had this impact in just over a month. We then hired Carlos on an as-needed basis for my daughter and son (5th grader). They both considered him a friendly and supportive tutor. He was crucial when school went remote for my son and helped him not fall behind through almost daily tutoring. He also helps my daughter apply for internships every summer, which she appreciates now that college applications are right around the corner. I honestly just want to say that after almost 4 years of his help, I recommend Carlos to everyone I can without hesitation.

    My daughter truly appreciated Carlos' knowledge and ability to help her learn the material. She called him, "a professional tutor."

What is your typical process for working with a new student?

When I start working with a new student, I will sit with them (and often their parents or caregivers) to determine what it is they are looking for. Sometimes students need help catching up and benefit from more academic support as we cover and review topics they may not have expertise in. Other students may need to develop better ways to study or devise better ways to approach a topic. Yet other students want to practice to prevent test anxiety or to prepare for challenging tests such as the AMC, SAT, or GRE. I will talk about our end goal, share my assessment of what I think is the best path forward, and discuss milestones in the short- and long-term. Then we get to work with a steady routine and revise our plan as needed.

What education and/or training do you have that relates to your work?

Bachelor's degree from Pomona College in Chemistry. Extensive coursework in biology, physics, mathematics, and psychology. 

I have worked in clinical research for over two years, devising early diagnostic tools for diabetes and certain types of cancer. This experience has allowed me to gain expertise in higher-level life science and physical science concepts. 

Currently a graduate student at UC San Francisco studying global health with an emphasis on chronic disease management.

I am also a great writer and have enjoyed English/Humanities courses. I scored a perfect score on the GRE Analytical Writing Section and have received scores in the 99th percentile for the MCAT, SAT, and ACT.

As a college volunteer interviewer, I also have experience in college application prep, college application essays, and interview prep.

Do you have a standard pricing system for your lessons? If so, please share the details here.

All high-school and introductory college courses: $55/hour for 1.75 hours or less per week and $50/hour for 2+ hours per week. 

Advanced college coursework (i.e. organic chemistry, linear algebra, differential equations, multivariable calculus, advanced molecular/cellular biology, upper-level psychology courses, etc.): $65/hour for 1.75 hours or less per week and $60/hour for 2+ hours per week. 



SAT/ACT: $85/hr

GRE: $95/hr

MCAT: $95/hr

College prep (i.e. help on college essays, preparation for interviews, general guidance): $75/hr

Group tutoring sessions are discounted based on the number of students working together.

This pricing covers all face-to-face time. I do not charge for quick questions outside of our scheduled lessons as long as they take less than a cumulative 20 minutes each week and can be answered over text or email. I also do not charge for preparing or grading material outside our lessons.

Prices may be negotiated on a case-by-case basis.

How did you get started teaching?

When I was a sophomore in high school, an advanced placement opportunity allowed me to take coursework at a local college. I took several math courses during my first semester and, upon seeing my performance, my professor advised me to seek work at the college's tutoring center. Most of my students never knew I was actually in high school, but those who did were always supportive and would recommend me to their friends and acquaintances. Eventually, I started private tutoring on my own, keeping a handful of students at any given time for the past nine years.

What types of students have you worked with?

I have tutored students aged 8 to 28. I have worked with students who need a lot of extra support and others who simply want someone to help them review for tests. Over the years, I have tutored many students who had straight As and were struggling in one class as well as students with around 2.0 GPAs (those were able to bring their grades to a 3.4 or above over a couple of years). I have also worked with students who really don't like a subject and others who want to delve into it much more than their classes allow them. Each student is unique, so it suffices to say that I feel comfortable approaching every type of student and finding ways to accomplish what they have in mind.

Describe a recent event you are fond of.

I have been working with one student for over 6 years. When I met them, their GPA was a 2.0 and they were ready to give up on college. I helped them through most of their coursework over 4 years in college. Their major GPA was an almost perfect 3.92 and their overall GPA a 3.6 by the time they graduated college. By then, they were a McNair Scholar and a very prolific researcher. Recently, they just finished their Master's degree and are ready to go onto their Ph.D. at a top university. Seeing them get this far has been an incredible feeling and honor.

What advice would you give a student looking to hire a teacher in your area of expertise?

Having time to learn without many other obligations is such a privilege; I personally miss high school (at least the learning part) and college dearly. Find someone who makes the learning enjoyable instead of burdensome and who you feel is approachable so that you can ask all the questions you may have!

What questions should students think through before talking to teachers about their needs?

Every case is very different, but generally, I think students should be honest about their goals. If all you want is to pass that test, we can study and get you an A. If you want to review the material to make sure you truly understand that, then I am all in for that too. If you want a challenge and feel ready for it but want someone on your corner for when you're stuck, I am also happy to help. Just think about what you want and we can find a way to get there!
