Our Practice


Mountainland Therapy was founded by David Siegfried P.T. and the late Donald Nelson P.T. in the spring of 2000.  Mountainland Therapy's mission is to provide, competent, professional, one on one Physical Therapy services to the residence of Grand County. Our goal was and is to provide a unique rehabilitation environment where the patient's needs come first. Treatment is delivered on a one-on-one basis with one Therapist managing the patient's care from start to finish. Patients won't feel as if they are being "shuttled" through the system and will receive care delivered with a personal touch. The purpose for our approach is one simple reason, treat patients the way you would want to be treated. We feel that this element of healthcare has been lost.




"Such a caring and qualified PT!! Very intuitive and understanding...flexible with scheduling and personable, as well!"   Kelly G.

"If you want a top notch Physical Therapist you can't beat Dave. Unfortunately I have had several sports injuries that required surgery as I am a very competitive athlete. Having an excellent PT is every bit as important as having an excellent surgeon and we are very fortunate to have Dave in this area as people with his professionalism and knowledge are hard to find in rural Colorado. I would highly recommend Dave if you ever have a need for a PT."

"My husband and I have been using Mountainland Therapy for a number of years, for a variety of issues. Prior, I had tried numerous ways to help with pain and numbness from an old ski injury. Dave evaluated my shoulder and neck, and developed a treatment plan. With office visits and home exercises to increase flexibility and strength, the pain has decreased, and daily tasks are easier." Deb C.

 " I had been battling back pain for months and had been to several practitioners to no avail. Dave listened to my symptoms and suggested a different approach than anyone had tried before. I was skeptical but desperate to get rid of the pain. I walked out of the office almost fully pain free. Within 3 weeks I was completely pain free and I had a complete understanding of what was causing my pain and ways to prevent it from reoccurring. Thank you!!! Mary H.
