APD Orthopaedics is committed to providing high-quality, personalized care for diseases and injuries that affect the body’s musculoskeletal system (the system of muscles, joints, and bones that keeps your body moving). 

APD enjoys a growing reputation as an intelligent choice for patients who need specialty surgery, especially in orthopaedics and neurosurgery. Our patients appreciate receiving their care in an intimate, community-oriented setting. Right here in the Upper Valley, patients have access to a deep team of surgeons and physician assistants who work closely together to meet patient needs.

“Today, we can address a wide range of orthopaedic needs at APD,” says Dr. Len Rudolf, who specializes in spine surgery and helped to establish the department more than nearly three decades ago. APD’s team of four orthopaedic specialists include Dr Rudolf, hand specialist Dr. Diane Riley, hip and knee replacement specialist Dr. Ivan Tomek, and Dr. John Houde, a general orthopaedist with a focus on sports medicine.
