Physical Therapists

Drs. James and Kate Spencer


Kate and James met in PT school at Northeastern University in Boston, MA where they graduated in 2006, each with honors. They strongly believe in hands-on treatment balanced with specific exercises in any recovery. 

Both therapists are Board Certified Specialists in Orthopaedics (OCS) and Certified Strength and Conditioning Specialists (CSCS). They have experience treating everyone from children to professional athletes to the medically involved.  In addition, they have extensive experience in a variety of populations and across the lifespan.

From 2007 to 2016, Kate and James worked as Physical Therapists in Aspen during the winter, but all across the United States during the summers. Their mutual obsession with skiing eventually drew them to Aspen fulltime in 2016.

Dr. Kate Spencer, DPT


I started my physical therapy career in Maine working for a private practice that specializes in therapist education, manual therapy, and treating the US Ski Team. Afterwards, I took on travel therapy for 10 years treating people of all ages, cultures, and medical acuity across the country. 

I believe hands on techniques improve the effectiveness of injury-specific exercises. I have advanced training in many different manual therapy techniques as well as dry needling. I use medical research and best-practice models in selecting exercises for my clients. My primary goal is to choose techniques that are effective and easy for clients to incorporate into their already busy lives, no matter their goals. 

I love spending time with my family and exploring the outdoors. I dabble in competitive uphilling, cross country ski racing, and running, but also love baking and reading a good book. I am a member of and serve in several positions for the American Physical Therapy Association. 

Dr. James Spencer, DPT


Early in my physical therapy schooling and career, I pursued a path in professional sports. I started my career working with the Boston Celtics, but later set out to find a more diverse path. Through 10 years of traveling physical therapy, across much of the US, I have seen patients in every setting and of many different backgrounds, cultures, and health conditions. Now, Kate and I have settled full-time in Aspen where we love working with all the different and fascinating personalities, including world class professional athletes trying to get back to the top of their game.

Skiing is my passion in the winter. In the summer, I enjoy running, hiking, and open water swim races. Much of the rest of my free time is spent volunteering in national leadership positions within the American Physical Therapy Association. I currently serve on the Board of Directors of APTA's Academy of Orthopaedic Physical Therapy - the national body representing musculoskeletal Physical Therapists. Additionally, each year, I travel to Washington, DC to meet with members of Congress, advocating for issues affecting PTs and our clients.
