Andres Uribe
Personal Trainer
As a child, Andres always struggled with asthma. Once, Andres was sent to the hospital for an entire week due to his asthma. At the hospital, Andres developed Pneumonia and at this moment he realized the only true way to help manage the strength of his lungs was to exercise.
Since then, Andres has devoted fifteen years of his life to martial arts, where he was able to not only learn how to defend himself but also how to control his breathing through countless hours of breathing and meditation training. In between those 15 years, Andres also participated in multiple sports being a part of the Varsity football, wrestling, cross country, and track and field teams. Andres was also the captain of wrestling and track, which led him to the goal of always being a leader and teacher to others. This led him to now want to help as many people as possible, showing and teaching everything he knows to others to help them succeed not only in sports but also in life. Andres has been a Martial Art Master instructor for 7 years teaching kids, teens, and adults of all belt levels. He has also been a swimming instructor for 4 years teaching young children that were too scared to even touch the pool water to competitive swimmers.
Now Andres has achieved his goal of becoming a personal trainer with a certification from the National Council on Strength and Fitness and continues to help teach and coach others what he has learned to help everyone achieve their fitness goals just as he has. With his experience through fitness, he helps provide personalized programs for everyone so that they can become the best versions of themselves 110% of the time each and every day.

Priscilla Cromer, CPT
Priscilla Cromer
Personal Trainer

At the age of 10, Priscilla was watching soccer icon, Brandi Chastain, on TV. This motivating figure inspired Priscilla to begin her fitness journey. She enrolled in her 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 her road to recovery. After making this discovery, Priscilla earned her 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 continuously finding avenues to gain more knowledge about fitness mechanics as well as other ways of working muscles to make exercising more fun. Priscilla helps her clients reach their fitness and health goals as well as builds their confidence in what their bodies are capable of.
