Gabby is a Doctor of Physical Therapy with advanced expertise in gait analysis, biomechanics, and athletic performance. She earned her Bachelor's in Exercise Science from UNH and her DPT from the University of New England, and she spent 4 years at the Spaulding National Running Center. After five years in traditional healthcare, she founded The Run Rx to close the gap between rehab and lifelong performance. Today she leads the team and the clinical vision behind every plan of care.
Her case report on the SFMA was published in the International Journal of Sports Physical Therapy, and she has presented on running gait analysis at the Harvard Medical School Sports Medicine Conference. She is also certified in strength & conditioning, clinical exercise physiology, and pre/postnatal exercise.
Outside the clinic: You'll find Gabby with her husband, two kids, and their goldendoodle Ziggy. She's a proud Boston sports fan and self-described washed-up basketball and soccer player who still loves running and snowboarding. Her perfect day: the beach, a good book, and a cold IPA.

Jess is a Doctor of Physical Therapy, Certified Strength & Conditioning Specialist, and certified Run Coach who treats both orthopedic and pelvic floor conditions. She holds advanced pelvic health certification through the Herman & Wallace Institute. She earned her Bachelor's in Biology from Framingham State and her DPT from Simmons University. She has led the development of pelvic floor programs at two clinics and regularly teaches workshops on pelvic health, running performance, and training theory.
Her movement background started in competitive gymnastics and coaching, but it was running that shaped her path. She has shaved more than 10 minutes off her own half marathon PR.

Ellie is a Doctor of Physical Therapy and Northeastern University graduate with a passion for helping runners, athletes, and active people get back to what they love. She found her way to PT after rehabbing her own ACL tear in high school, so she knows firsthand what it takes to come back from an injury, both physically and mentally.
She played both soccer and lacrosse in college, and she's an avid runner who finished her first marathon in Hawaii. Ellie is curious and thoughtful in her care. She takes the time to understand the person behind the injury and is always looking to learn and grow. She'll help you build strength, resilience, and confidence for the long run.
Outside the clinic: Ellie grew up in Hopkinton, NH, as the oldest of three, and her family ran an animal rescue when she was growing up. These days you'll find her running or walking her dogs, lifting at the gym, or heading to the beach.
