Challenger Middle School Families, I am truly honored to be a part of the Challenger community that I have known for the past 16 years.

In 2007, my growing family and I moved to Huntsville where my wife, Dr. Evelyn Frazier-Coln, was launching her solo family dental practice. We have 4 beautiful children: James David (17), Emma Kate (15), Anderson (12) and Finley (9).

I am a firm believer that we are all members of one team, Team Challenger, and that we must work together and support each other in order to achieve the common goal we all share: to prepare our students for success. I vow to lead us in building positive relationships, modeling good citizenship, maintaining effective communication, and committing to the principles of servant leadership in all we do. I look forward to working with each of you as we begin a new school year and a fresh chapter at Challenger Middle.
