I enjoy working with students and helping them feel more confident when it comes to math. I like creating a space where students feel comfortable asking questions and figuring things out step by step.
Outside of work, I’m a mom of three, so I’m always around kids and learning in some way. I enjoy reading, being creative, and finding fun ways to keep learning interesting.

Hey There! I’m Coach Davin
Hello! Growing up I've always loved math, and in my junior and senior years of highschool I even had the pleasure of tutoring my peers in Calculus, as well as other subjects. In that time I learned that I love to teach things I'm passionate about to others, and help them understand it the same way I do. A personal interest of mine is games of all sorts, and also how math is involved in or can be used in games!

Why was 6 afraid of 7?
- Because 7, 8, 9!
Hello! My name is I’Yanna, and I am an accounting major at Austin Peay State University. I’m a military brat whose parents as well as my sister have both served. In total, I’ve lived in 7 different states, now including Tennessee. In fact, numbers come so easily to me that since middle school, my mom told me that I would make a great accountant one day. Fast forward to now, I’m an accounting major in college! What I enjoy most about working with students is hearing about their personal interests/hobbies and finding a way to covert that into a math problem that we can work as a team to solve.
