Foot & Ankle Providers
Each adult foot has 26 bones along, 33 joints, 107 ligaments, 19 muscles and many tendons that hold everything together. Add to that a complicated system of fascia, nerves and blood vessels and it doesn't take an expert to realize you may need an expert when things go wrong.
The OPA Foot & Ankle Clinic is home to foot and ankle specialist Eugene Chang, MD — the only fellowship-trained foot and ankle doctor in Alaska, and one of the very few surgeons in the United States with experience in total ankle replacement surgery. He focuses exclusively on treating foot & ankle related conditions.
At our Wasilla office, surgeons Deryk Anderson, DO and Tucker Drury, MD treat Mat-Su valley patients with many foot and ankle conditions and have extensive experience in sports medicine. They often team up with Dr. Chang who holds clinic for foot patients in the OPA Wasilla office twice a month.
Other OPA foot providers include Dr. Greg Schweiger, a sports medicine surgeon who also has fellowship training in orthopedic trauma surgery.
