About Ph.G. Tutoring

Meet Phil Grizzard, Ph.D.

I love tutoring math. It’s as simple as that.

I am fully qualified to tutor any math course from elementary school up through the college graduate level. This includes the entire calculus sequence and well beyond, as well as math-heavy courses like statistics. (While there are a few highly advanced, upper-level college math major courses I might be less comfortable tutoring, always feel free to reach out so we can discuss it!)

While I do enjoy diving into high-level mathematics, what sets me apart from many Ph.D. mathematicians is how much I enjoy working with students who are struggling with the basics. Over my decade and a half of experience as a professional tutor, I’ve worked with hundreds of students. I have learned exactly how to meet a student right where they are—whether that means figuring out how to prove a vector space or simply re-learning how to add fractions—and building their confidence from there. And for students looking for enrichment or to explore new levels of math, I have the expertise to show you concepts you’ve never seen and that your teachers probably don’t know.

On a Personal Note...

I grew up here in Normal and graduated from Normal Community High School in 1994. Later that summer I met my wife Christine, and we got married in 1999. In 2015, we welcomed our oldest son, Zach. Then in 2024 we adopted our youngest son Miah and our daughter Aubrie. All three kids are within two years of each other, so they keep us pretty busy!

In addition to tutoring, I am also the part-time campus minister for AGAPE/Judson Fellowship at ISU. As for hobbies, I’m a big sports fan, particularly MLB baseball, WNBA basketball, and PWHL hockey. I enjoy writing, and I am an occasional columnist for the Pantagraph newspaper.

As for my retirement plans? I’d like to… do some math tutoring 🙂
