Don Buethorn CPO, Founder and Owner, Cascade Prosthetics and Orthotics

Don Buethorn

After first earning a Special Education degree from Western Washington University, I decided to pursue the field of prosthetics and orthotics. I returned to school at the University of Washington School of Prosthetics and Orthotics and graduated in 1980.

After graduating, I served a two year internship in Boise, Idaho, upon completion of which I started my own company, Cascade Prosthetics and Orthotics, in Bellingham, WA. Since then I have devoted myself to the development and application of a specialized system of pediatric bracing, called Dynamic Ankle Foot Orthoses, or DAFOs.

I have been working at Cascade Prosthetics & Orthotics since April of 1994 where I began my career. I had just graduated with my second degree which was a B.S. in Prosthetics and Orthotics from the University of Washington. I began with my internship at Cascade which has now blossomed into 15 years and counting. I began college with an interest in the field of Physical Therapy. I was introduced to the field of Prosthetics and Orthotics when I was volunteering at a hospital in Everett.

I met a prosthetist who was working with one of the patients who was in physical therapy after a recent amputation. I thought it was an interesting career so I decided to apply to the program at the UW. I have always had a passion for helping people. I graduated with a B.S. degree in Prosthetics and Orthotics in 1994. I am a certified prosthetist and orthotist and am the clinical manager of the Ferndale office. When I'm at home I really enjoy spending time outdoors like camping, hiking, yard work and playing with my dogs. I have several horses and love hitting the trails to ride!

I graduated from the University of Washington in 1992 with a Bachelor of Science degree in Prosthetics and Orthotics. I was first introduced to Prosthetics and Orthotics at a very young age by my mother who made prosthetics and orthotics for people in need in India.

Since graduating, I have worked for Cascade Prosthetics & Orthotics as the primary Orthotist/Prosthetist and Manager of the satellite office in Mount Vernon, WA. I specialize in dynamic bracing and travels around northwest Washington to evaluate and cast children in need of DAFOs. My favorite things about my job is working with people and making a difference in patients' lives.

I am Board-Certified through the American Board for Certification in Prosthetics and Orthotics, and also hold Washington State licenses for Prosthetics and Orthotics.

When I am not working I can usually be found at the golf course. I also enjoys training for triathlons and mountain biking.

People often wonder how I got interested in this unique field of orthotics and prosthetics. I spent an afternoon observing at a P&O clinic during my senior year in high school. When I saw a resilient 7 year old boy run out of the office on his refurbished prosthetic leg, I knew this was what I wanted to do!

In 2002, I graduated from the University of Washington with a BS in Prosthetics and Orthotics. I spent the first seven years practicing in Salem, OR, where I received my American Board Certification in both prosthetics and orthotics. I'm excited to be a part of the clinical team at Cascade Prosthetics & Orthotics. With their emphasis on clinical excellence and complete patient satisfaction, I'm excited to continue serving my patients and improving their quality of life.

When I'm not working, I enjoy spending time with my family, mountain biking, or indulging my passion for travel and the Spanish language in South America.
