At the age of 10, Priscilla was watching soccer icon, Brandi Chastain, on TV. This motivating figure inspired Prciscilla to begin her fitness journey. She enrolled in my local soccer program, but after several seasons of playing she sustained a knee injury that kept her from playing contact sports. She had to shift gears, unable to participate in fitness the way she had known up to this point. At this time, she uncovered weight lifting and through weight lifting, she gained an understanding that all muscle groups whether big or small were crucial in my road to recovery. After making this discovery, Priscilla earned my certification as a personal trainer to help others overcome their fear of reinjuring themselves as well as building their confidence around fitness. She is a firm believer that everyone should have access to the knowledge and experts that will help them obtain their fitness goals. This passion led her to obtain a business degree through San Jose State University as well as putting her on the road to obtaining a Master’s degree in Kinesiology.
Tony lettered in three sports in high school- soccer, football, and lacrosse. It was in the dingy high school weight room that he fell in love with weight lifting, but he would not understand how to refine his pursuit of strength until years later. He got my BS in psychology at Allegheny College in Pennsylvania. He played soccer in college, and got into performance fitness while lifting weights in off season training. Over the course of his athletic career, he sustained several broken bones, concussions, and muscle tears, and working with the athletic trainers at his college sparked my interest in physical therapy and sports medicine. He’s now certified in personal training and nutrition coaching, and is considering a career in physical therapy. He enjoys training athletes for performance, but his most rewarding clients are the ones who he can dissuade of the belief that they have lost some ability-whether to injury or age. He’s been coaching since 2017, and his current goal is qualifying for strong first barbell certification. When he’s not pursuing fitness, Tony’s at a recording studio working with artists and podcasters to cut and mix their projects.
