David P. Zamorano, MD, FAAOS

Dr. Zamorano graduated from UCLA with a degree in Microbiology and Molecular Genetics. He then went on to earn his medical degree at the University of Southern California. He completed his orthopaedic residency at Harbor/UCLA Medical Center, followed by an Orthopaedic Trauma fellowship at the University of Texas in Houston and a pelvic/acetabular fellowship at Good Samaritan Hospital in Los Angeles. Dr. Zamorano specializes in orthopaedic trauma surgery, which consists of providing care for patients who have sustained fractures and other injuries. These injuries are often the result of:

  • Car, motorcycle, or bicycle accidents
  • Outdoor activities, horse-related, or sports injuries
  • Slips, trips and falls

Dr. Zamorano began his career as a professor at the University of California, Irvine, Medical Center. He spent 12 years as the Director of Orthopaedic Trauma where he enjoyed teaching Orthopaedic Surgery residents and medical students. In 2016, he came to Boise, Idaho where he became the Director of the Orthopaedic Trauma Service at St. Alphonsus Regional Medical Center. After 6 years as an employed surgeon at St. Al’s, Dr. Zamorano has decided to become an independent surgeon so that he can focus on patient-based care. He is excited to take the knowledge and expertise that he has gained in the last 17 years, and provide exceptional care for all patients in the Treasure Valley. When not at work, Dr. Zamorano enjoys spending time with his family, exercising, golfing and camping.
