Our Amazing Staff

All our trainers are specially certified Functional Training Experts, with extra education in helping active adults enjoy safe, fun and effective workouts.

Orange County native Rosa Coletto created Full Circle Fitness with a mission: To help older people – usually ignored by the fitness industry – get in shape to enjoy their best lives. Rosa had been a personal trainer for six years by then, and she wanted to meet this need in the community. She knows that fitness over 50 is the best way to stay healthy and vital, to enjoy life on your own terms, and to remain happy and independent for as long as possible. She is a certified Functional Aging Specialist, Brain-Health Trainer, and Peak Pilates instructor – as well as the leader of OC’s only team of trainers all certified to specifically train older people. When not at the studio, Rosa can be found relaxing at home, camping, or off-roading with her husband, Mike, their German shepherds, King and Mia, and cats Xena and Jackson.
