Coleman Kelley

Instructor
Hello! My name is Coleman. I graduated from Clemson University with a B.S. in Biochemistry and a minor in Psychology. I worked in the medical and research fields before deciding I wanted to try the teaching space. I love working at Mathnasium! The system is so effective in getting students motivated and it’s so rewarding to be able to help a student overcome a concept they are not quite understanding or to just encourage them as they learn new concepts. I enjoy the outdoors. Hiking, camping, snorkeling, pickleball, you name it, I’ve probably tried it, but that doesn’t mean I don’t also enjoy a night in with a good movie and my cat, Jupiter.

Anna Nippoldt

Hi, I am Anna. After a nine-year career of gymnastics coaching, I am here at Mathnasium teaching something else I love…math. I studied mathematics and economics when I was in college, attending the College of the Sequoias and the University of California, Los Angeles. In my free time, I actively engage with a local church and also host children in my home who are at-risk of entering the foster care system. My favorite part of working at Mathnasium is connecting with each child who is at my table. I consider it an honor and a privilege to be a consistent influence in their life and witness them grow as a person and in their understanding of math.
