Founder: 2020

Dr. Zach cheered in high school but became serious about the sport when he joined the championship-caliber University of Delaware cheer program. There, he had the privilege of training with some of the most talented coaches and athletes in the history of collegiate cheer. He then worked as a health and fitness counselor while coaching All-Star cheer as he traveled the world on the NBA’s “Fan Patrol.” After joining the U.S. Peace Corps, he was struck by a car abroad and returned home to heal. During that time, his passion for Physical Therapy ignited, and he graduated from the #1 ranked University of Delaware Physical Therapy program. He understood that cheer required its own sport-specific training and rehabilitation, so he studied and developed cheerleading-specific rehab protocols and training interventions to keep up with the sport’s increasing physical and mental demands.

Director of Operations since 2022

Marybeth had a passion for sports and fitness since her youth and began by starting All-Star cheerleading early on. Her small high school did not offer team sports, so she organized a co-ed competitive cheer team for the school. She then spent several years teaching cheer camps, power tumbling, and choreography across the country. She worked as an instructor for the Philadelphia Eagles Junior Performance team that performed during NFL pregame and halftime shows. Marybeth spent several years volunteering for and on the board of nonprofits to help underprivileged children internationally and continues to make this work a priority. Upon meeting Dr. Zach, she saw that Unlimited Performance’s philosophy of the proper teaching of biomechanics and positive self-belief aligned with her own beliefs. It’s her mission to set young athletes up with life skills that they can tap into to achieve any goal.
