Dr. Tyndall is a board-certified orthopedic surgeon and fellowship-trained in sports medicine and arthroscopy. He focuses on evaluating and diagnosing sports injuries and disorders of the upper and lower extremities, and providing effective and affordable treatment plans. Dr. Tyndall always considers the traditional nonsurgical methods for effective pain relief. When surgery is necessary to resume a healthy lifestyle, he will perform advanced, minimally invasive procedures that will ultimately reduce the recovery time.

Dr. Tyndall is the first surgeon to complete a NextAR shoulder procedure in the state of Pennsylvania. NextAR is the first platform to offer personalized augmented reality solutions for both joint replacement and spine procedures.

While Dr. Tyndall is recovering from a long work week, he resides in Hollidaysburg, PA with his wife and three children. They enjoy the outdoors, time with family, biking, running, and skiing.
