Welcome! Thanks for visiting the Ph.G. Math Tutoring Education Platform
My name is Phil Grizzard, and I’m a private math tutor in Bloomington-Normal, IL. I have a Ph.D. in math, and I’m also secondary education certified in the state of Illinois. This enterprise began with me as the only tutor, but we have now expanded to multiple tutors, all specializing in mathematics.

We tutor just about all levels of mathematics -- both online and in-person. We tutor middle school, high school, beginning college, and even advanced college levels. We can help you for the short-term to get you through an exam, or for the long term to help you through a course or sequence of courses. No matter your material level or confidence level, we’ll meet you where you are and help guide you to where you want to be.

There were many times I didn’t understand something, and he actually cared and explained how to do the problem and why we solved it that way, without just giving me the answer. Thank you so much for helping me Phil! :))Posted on Nathan HansingTrustindex verifies that the original source of the review is Google. I really enjoyed working with Phil and he's a great tutor! He helped me get through some difficult topics for me in my AP Calc class. He was able to explain stuff clearly and helped me feel more confident in my calc knowledge!Posted on Jane HostertTrustindex verifies that the original source of the review is Google. Dr. G responded quickly over the summer when I needed help with my summer Calc 2 course. He gauged where I was with my math skills and was able to help me with all of my questions! I never felt judged if I didn't know an answer; I could tell he genuinely wanted me to learn. He was a great resource and I highly recommend him as a tutor.Posted on Ethan CoulterTrustindex verifies that the original source of the review is Google. Phil is a great tutor who has recently helped me with MAT119 (College Algebra). He gives clear notes and shows examples that make topics easier to understand. Instead of just showing you how to do it, he explains how it works and makes it interesting. Phil will let you lead the session if you want, but still makes sure you cover everything you need. He’s also super kind and easy to talk to, so you can even make a friend if you want. I highly recommend him!Posted on Camryn MrazTrustindex verifies that the original source of the review is Google. Got tutoring for my math 130 class which I had failed the first time and needed to take again to be able to move on! I improved so much with his help and I am so grateful that I was able to have him as my tutor and guide me through the process!Posted on Robert KidwellTrustindex verifies that the original source of the review is Google. Phil is a conventional and straightforward Math teacher; he is patient and encourages you to understand the concepts and reasoning behind the math problems you are working on. I went from a D- to an A- by the end of the term, thanks again Phil for all your wisdom and help. Sincerely, Robert KidwellPosted on Avery_mfTrustindex verifies that the original source of the review is Google. I WOULD ABSOLUTELY RECOMMEND PHIL!!!! I began getting tutored by Phil mainly for Arithmetic in march, I went about once a week for 3 months and in just that short amount of time the progress I made was INSANE! Phil will explain every way to solve a problem and make sure you fully understand how and why you got the answer to a question. He is very patient and understanding, I felt absolutely no judgement when I didn’t know something fairly basic and he talked me through every step if I didn’t understand something. I feel like I learned more in those 3 months than I did in a full year of high-school math. He is super kind and very flexible with his schedule. I appreciate all of the help he was and because of his help I was confident in my ability to take my entrance exam for college and passed. Thank you so much Phil!Posted on Cade MahanTrustindex verifies that the original source of the review is Google. Great tutor, helped me a lot in precalc and also raised my math act score to a 28Posted on Addy ThomeTrustindex verifies that the original source of the review is Google. I LOVE PHIL, HE IS THE BEST! I've been working with him for 2-3 years, and he's helped me immensely. He understands all of my questions and always explains things as many times as it takes for me to get it. Plus, his office is really cozy and he always has a ton of cool pens, paper, and math posters in his room. He is kind, intelligent, and passionate about learning. I couldn't recommend more! He has helped me with Algebra 2 Trig as well as AP Pre Calculus and has been immensely helpful with both.Posted on Stephaney JonesTrustindex verifies that the original source of the review is Google. Phil worked with my high schooler this spring to help build his Algebra 1 skills. He was very thorough and flexible. My son was able to come a long way in the amount of time we had. He was able to fill in a lot of gaps he had and began building a foundation for future learning.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
