Carl Diffee
PARTNER
Carl began working with ASP in 2022. Prior to joining our team, Carl spent 12 years as a high school football coach in Mississippi and Tennessee. Upon graduating from the University of Mississippi, he began his professional career at North Panola High School in Sardis, MS. Over the next four years North Panola won 24 games and made the playoffs each year, a marketable improvement from back to back 1-9 seasons before his arrival. In the spring of 2016, Carl took over as the Head Football Coach and quickly took North Panola to the top of Class 3A, winning 46 Football games and back to back district titles in his four years. 23 of his players signed college scholarships during that time. In addition to his success on the field, Carl raised over 2 million dollars during his tenure to upgrade nearly every aspect of the facilities at North Panola. In 2025, this effort culminated in the construction of a new Turf Field.
In 2019, Carl was introduced as the Head Football Coach at Milan High School in Milan, TN. In his first year, the Bulldogs won 13 straight games before falling in the State Championship game to Alcoa. While at Milan, Carl spearheaded the Turf fundraising campaign designed by ASP, successfully raising over 1 million dollars.
As Partner at Athletic Surfaces Plus, Carl strives to make an positive impact on every person he meets. This passion for people is evident in the way Carl treats his clients.
