Cathy Campbell, PT, DPT, SCS, FDN-2
Dr. Cathy Campbell, PT, SCS brings more than 20 years of experience in physical therapy—as a patient, student, and clinician—shaping a deeply empathetic and performance-driven approach to care. A former competitive gymnast, she spent years rehabbing injuries and recovering from surgeries, experiences that ultimately fueled her passion for the field. With the support of skilled physical therapists, she went on to become a two-time USAG All-American and an Ivy League Champion at Cornell University. That journey inspired her to help other athletes navigate recovery and return to their sport stronger than before.
Dr. Campbell earned her Bachelor of Arts in Biological Sciences from Cornell University and her Doctorate in Physical Therapy from Sacred Heart University. She continued to advance her expertise in sports and orthopedic rehabilitation, becoming a Board-Certified Sports Clinical Specialist (SCS)—a distinction held by fewer than 2,000 physical therapists in the United States. Throughout her career, she has worked with athletes at every level, from amateur to professional and Olympic competitors, including a World Champion.
Her professional experience includes working with the United States Coast Guard Academy, NYU Rusk Rehabilitation Institute, and STAR Physical Therapy in New York City, where she treated a wide range of complex conditions and high-level athletes. She also led one of the most successful clinics on the East Coast, building a reputation for exceptional patient outcomes and strong team leadership. Now back in Colorado, Dr. Campbell is excited to continue that level of excellence while helping her patients achieve their personal and athletic goals.
Outside of the clinic, she enjoys taking full advantage of Colorado’s outdoors—skiing, hiking, and running with her husband, three daughters, and two dogs.

Dr. Ally Reyes earned her Bachelor of Science in Kinesiology from Indiana University and her Doctorate in Physical Therapy from Indiana State University. A lifelong athlete, she played soccer and competed in cross country and track before continuing her running career at the Division I level at Butler University. After experiencing two stress fractures, she developed a deep appreciation for the importance of having a trusted clinical professional who provides education, support, and guidance throughout the injury journey.
Ally is passionate about helping runners recover from injury and return stronger. Her areas of expertise include run/walk gait analysis, return-to-sport protocols following ACL reconstruction, and both surgical and conservative management of hip labral pathology, femoroacetabular impingement (FAI), and dysplasia-related pain. She also specializes in pelvic floor dysfunction and lifting mechanics, bone health and stress injury prevention, and rehabilitation for shoulder rotator cuff and labral conditions.
Her approach to care is investigative, individualized, and aligned with each patient’s goals, with a focus on making treatment both effective and sustainable. She believes healing can be a positive experience and brings humor and lightness into her work to help patients feel supported and empowered.

She has also provided training room and event coverage for local high school athletics and USA Ski & Snowboard, as well as Emergency Room coverage for orthopedic injuries sustained on the mountain. Dr. Hsing has a particular interest in working with endurance athletes, as well as treating lumbo-pelvic-hip dysfunction, chronic pain, and supporting post-partum athletes in safely returning to sport.
Before transitioning into physical therapy, Dr. Hsing earned her Bachelor of Science in Finance from New York University’s Stern School of Business and worked in both research and finance in New York City. During that time, she remained deeply connected to her passion for movement through running, participating in local running clubs and competing in races—including eight road marathons and a 50k trail race. Ultimately, this passion led her to pursue a career in physical therapy, where she could combine her analytical background with her love for athletics and human performance.
Outside of the clinic, Dr. Hsing enjoys spending as much time outdoors as possible—running, climbing, hiking, and skiing. On slower days, she can be found in the kitchen cooking and trying new recipes or relaxing with a good game of college basketball.
