Athletic DNA (ADNA) is an American sports apparel company specifically designing for tennis players. Founded in Seattle in 2007, ADNA began by training young tennis athletes, which evolved into sponsoring Select Junior Tennis players, and then expanded to manufacturing clothing for youth and adult tennis players. ADNA has since spread to professional tennis, and currently sponsors players on the ATP Tour[1] & WTA Tour.
Origins
Athletic DNA is run by former University of Illinois tennis player Mike Calkins, New Zealand Davis Cup representative; former University of Idaho tennis player Dan Willman; and Karl Wiersholm, father of nationally ranked junior tennis player Henrik Wiersholm.[2] The company began in Seattle when founders Calkins and Willman partnered to form an academy for junior tennis players.[1] The academy was successful, producing four No. 1 players in five years. Wiersholm then approached Willman and Calkins about branding what they had done with their junior tennis players.
