Originally from Miami, Oscar has been involved in sport and fitness as a “way of life” from an early age. Through his mentors, he excelled in wrestling in high school and at Michigan State University. In college Oscar was able to coach a youth wrestling program. He helped each child to perfect their wrestling technique and give them motivation to train for success. The children were so happy to have someone to help and that’s when he knew he wanted to be a coach/trainer.

After college Oscar joined the U.S. Navy and was deployed to the Persian Gulf on the USS Nimitz. While serving his country, he saw himself again in a position to help. His fellow sailors would approach him with fitness questions. Eventually, he became the physical fitness trainer of his command designing the workouts and programs.

The Navy brought him to sunny San Diego. Oscar decided to stay and become a personal and group fitness trainer and youth wrestling coach.

In addition, Oscar volunteers at Hoover high school as a wrestling and strength & conditioning coach. He feels it’s a way to for him give back by helping young students achieve success just like he did.
