Jessie DeThomasis graduated from the State University of New York College (SUNY) at Cortland with a BS in Economics. After working in finance for four years, she decided to pursue her passion for sports performance and athletics and became a Certified Strength and Conditioning Coach. She and her husband, Bobby DeThomasis started PTS in the fall of 2011, and then opened their own facility in January 2013.

Jessie specializes in structural balance, olympic lifting, strength development, sports nutrition, sprint/running programs, and body composition improvement. Combining science with practical application, she works with a variety of athletes, including track and field, hockey, football, soccer, and figure skating to improve their speed and power output.

Jessie has completed her Fascial Stretch Therapy Level 2 certification, is a PICP Level 2 Regional Strength Coach, certified BioPrint practitioner, and has attended several USA Track and Field Speed Summits as well as nutrition seminars hosted by Designs For Health, including functional endocrinology and approaching metabolic, thyroid and adrenal disorders.

Jessie’s own racing experience in distances ranging from the 100m to half marathon, helps her design personalized training regimens for a wide range of both sprint and endurance athletes. At SUNY Cortland, she was a member of the Indoor and Outdoor Track & Field team, where she had the opportunity to work with nationally ranked coaches. She competed in the 400, 4×4 and high jump. She has continued competing and is currently training for the 200m and 400m as a Masters track and field  athlete.

This year she improved her skills set as a Strength Coach by taking the Functional Range Conditioning (FRC) Certification and attended several private internships with renowned strength coaches and exercise physiologists.
