About Us
A3 Performance emphasizes the three key aspects that define an athlete: mental, physical, and spiritual. You might be the strongest person in the room, but if your mind isn’t engaged, you won't reach your full potential.
Whether you love golfing, playing pickleball, or simply want to touch your toes, we believe anyone can become an athlete at any stage in life, and we’re here to help you get there.
Our Story
Originally from a small town in South Carolina, Frank Childress dreamed of being a backup dancer for Justin Timberlake. However, after some early misadventures in his 20s, he realized that the dance floor might not be his path. He decided to make a fresh start in sunny San Diego, where he was recruited as a personal trainer at a large gym. It was there that he discovered his true passion for movement and community.
Since then, Frank has earned multiple certifications, transformed hundreds of clients, and established himself as one of the top trainers in North County, San Diego. In 2019, he met his wife, Hailey (in the gym, of course), and by 2021, they welcomed their first child, a son named Bishop. Together, they enjoy surfing, working out, and spending quality time with loved ones. Frank is always eager to expand his clientele and welcome new members into the family.
