 Tay Espinosa

Tay Espinosa was born in Chicago but raised mostly in Miami Florida. After graduating from the University of Miami with a bachelor’s degree in nursing Tay was commissioned as an officer in the Navy Nurse corps. She was stationed in the bay area where she met her husband Julio, a career naval officer.

In 1991 she was deployed to the Persian Gulf on the hospital ship, Mercy in support of Desert Storm. During the 9 month long deployment she began to run to work off stress. This habit continued upon return to the United States but seriously took hold about 10 years later when she ran her first marathon with Team in Training. The thrill and camaraderie of training for endurance events contributed to her interest in fitness and a healthy lifestyle. Going to a gym did not provide motivation or the “fun” factor she craved in her workouts until she found Fitness Revolution.

Tay has been an avid client since 2006. She has achieved and maintained a superior level of health and fitness through working with Jeff and Tiffany. Having the demands of two children and a very busy husband she strives to take care of herself so she can take care of her family. As a coach, Tay wants to help others reach their health and fitness goals. She believes everyone has the capability to achieve a healthy lifestyle with the workout and nutrition support of the Fitness Revolution Team.

While playing competitively may have ended, his passion for athletics never did, as he played intramurals in college and hoped to pursue sports at a professional level. In 2002 he began a coaching career, teaching middle school sports in the South Bay. Since then he has moved through the ranks coaching, club, high school and college basketball. Currently he coaches men’s basketball at Napa Valley College. His passion for teaching athletes to be successful both on and off the court is what keeps him motivated and enthusiastic about coaching.

Shortly after becoming a resident of the Napa Valley in August of 2011, Carson connected with Fitness Revolution/Athletic Revolution. Seeking a way to integrate fitness and basketball, FR/AR was an obvious fit. It was only a matter of time until he found the added benefits of camp. He hopes to share his passion of fitness and athletics with clients throughout the Valley, not to mention the vast array of knowledge and assistance FR/AR has to offer.

Carson, his wife of four years Katherine and their new son Conall, are really enjoying their new home in the Valley and their experience with FR/AR. They have found comfort in the family FR/AR has provided, and are off to a great start of a lifetime of health and fitness.

Joey Chapple

Success Coach

Joey was born and raised in Mountain View, California. Being active has always been part of her life. Activities such as piano, ballet, playing with her dog, and cruising the neighborhood on her Schwinn (yes, it had a banana seat and a basket). During high school, she played organized sports. Although it was more from a social aspect, to hang out with her friends, then as a competitive athlete. Fast forward, Joey landed in Napa to continue her job as a Marine Mammal Trainer, met her husband Patrick, and had 2 boys. Then after working as an animal trainer for 20 years, Joey went back to school and received her teaching credential. She has been an elementary school teacher since 2006.

As for Joey’s adult fitness journey, it is a progression. It started out as a weekend warrior with inconsistent workouts and poor eating choices. Then she became more focused and started planning on a couple different events a year to train and participate in. As Joey became more involved in the fitness community she liked what she saw. She was meeting like-minded people that encouraged and supported each other. This sparked her passion for health and fitness as a lifestyle, not just a fad.

With this new mind set she continued to gain knowledge and experience in health and fitness. Which is an ongoing learning process. Along the way, she joined Fitness Revolution as a member. It was Jeff’s philosophy and passion, as well as the coaches, for helping others achieve their fitness goals that really resonated with her. Joey wanted to be a part of that and eventually entered the internship program and is now part of the FR coaching family.
