About

Dr. Kennedy is a Hand and Upper Extremity Surgeon with subspecialty training in both Hand & Microvascular Surgery and Upper Extremity Sports Medicine and Reconstruction. He provides treatment options for problems of the Hand, Wrist and Elbow, including all forms of instability, trauma, deformity, and arthritis. Surgically, he performs open, arthroscopic, and microsurgical techniques.

Patient Care Philosophy

Giving the best care means listening carefully, sharing the best information, and helping each person make the best medical decisions for their needs. When surgery is chosen, it is undertaken with the greatest possible precision and care. Advanced practice providers, therapists, nurses, and other multidisciplinary providers are central to success.

Clinical Interests

Hand, wrist and elbow trauma; Elbow instability, stiffness, arthritis, or deformity; Arthroscopy of the wrist, elbow, and shoulder; Joint replacement (arthroplasty) of the hand, wrist and elbow

Personal Interests

Being outdoors in the Pacific Northwest. Spending time with family. Triathlon, hockey, and water sports. Reading about new ideas in education, technology, design, economics, sociology, and psychology.
