About
My name is Ray. I earned my M.A. in Teaching Mathematics at California State University, Fullerton, where I also taught as a professor for two years. You can find my reviews on RateMyProfessors.com. I currently teach at a university outside of Nashville. I have over 10 years of experience in education, including tutoring and high school instruction.
I believe math is best learned through understanding, not memorization. My goal is to help students think creatively and confidently about mathematics by exploring multiple ways to approach each problem. When applicable, I use Desmos (a graphing calculator) to demonstrate key concepts visually. You’ll learn to see math from both algebraic and graphical perspectives, building a deeper and more flexible understanding.
Outside the classroom, I create educational content on my YouTube channels — The Math Brofessor and Reckless Math — where I share lessons and problem-solving strategies in an engaging and approachable way. Feel free to check them out to get a sense of my teaching style.
Thank you for visiting my profile — I look forward to helping you grow in confidence and skill on your math journey.

Ray has been tutoring my daughter for over 3 months now and we have seen a great improvement in her math grade. I had tried three tutors before I found Ray and I am so thankful that we did. I explained to him that my daughter was having a difficult time in her Algebra class and that I was having a hard time explaining it, as it is the new common core method. I mentioned to him that my daughter is very shy and I wasn't sure he would get her to talk much but to my surprise, he really has done a great job in getting her to talk through each math problem. He engages my daughter and encourages questions especially when he suspects she isn't really sure on a particular math problem. I can't give enough praise to Ray; he is always on time and gets right to work, he never leaves unless he's sure my daughter understands the math lesson. My family and I are very pleased with the progress my daughter has made and we would highly recommend Ray to any parent that needs a mathtutor.

Ray is hands down the best tutor I could of found for my daughter!!! We've been working together for a month now and my daughter has got 2 "A's" on her tests. She actually for the first time, has a greater understanding of the problems she's trying to solve. He is so passionate about teaching math to others! That's what gets his students drawn into it. My daughter has always struggled with math and now she really enjoys it !! Best tutor EVER!!!

Ray was very patient and thorough when he tutoredmath with my 13 year old daughter. This was during the peak of the pandemic 2021, when schools were hybrid online and on campus. Ray was always punctual and effective. He explained the math questions thoroughly and solved the problems effectively. My daughter was able to understand equations and solve them the way her math teacher wanted. Thanks to Ray! I highly recommend Ray for mathtutoring.

I am a nanny for 3 elementary school-highschool aged girls. The youngest was struggling terribly with fractions and it was a battle every time she had to do homework. As much as I tried to help and break through her frustrations, I just couldn't. Until we found Ray. I figured it was about time to get her professional help. When Ray started his hour with her, her attitude was extremely pessimistic and negative. I was starting to worry that no one could get through. However, as Ray began to really break things down, and approach problems in a way I never would have thought of, you could just see the road blocks come down as she truly began to understand it. Towards the end of the hour, I overheard her say "WOW. I actually get it!! This is actually FUN!" ... I got a little emotionally hearing her say that, because the past few weeks had been such an exhausting battle for the both of us. If you need a tutor that will not only find a way to get your child to understand a concept, but actually change their total outlook on math, Ray is absolutely this tutor. Don't miss out on this young aspiring math teacher.

We were in a panic situation! Grades where being posted the following week, and my son needed to bring them up! I explained to Ray my son's teacher would allow him to retake a test to improve his score, and Ray sprang into action! The following day, he arrived at our house in the evening and went straight to work, asking my son detailed questions regarding what the test was on, examining my son's math work, and what parts he was having trouble with. Ray stayed for nearly two hours that night, and returned the following day to cover a few more problems, and review the previous nights work. He also gave my son a lesson on how to use his scientific calculator. I have Ray on speed-dial now. He's our goto guy for High School math now! I would also consider him for College level mathematics after my son graduations.
Ray knew how to by-pass, breakdown and explain Common-Core math problems. His professional attitude was refreshing, his knowledge of math impressive, but his ability to interface with my son, make him feel comfortable, and instill confidence is priceless! Thanks Biggerstaff! Job well done!

What education and/or training do you have that relates to your work?
I have been tutoring for over 5 years: private and with a business. In regards to businesses, I have worked for Glendora Learning Center (Math and Spanish tutor), the Azusa Pacific University Math Center (Math tutor), and the APU Learning Enrichment Center (Math and Spanish tutor). In regards to math, I am in progress of getting a bachelor's in mathematics. In regards to Spanish, I have lived in Ecuador on two occasions where I stayed with a Spanish-speaking family.
