Dr. Barnett is involved in community and physician education and has presented at numerous conferences nationally and is published in many journals on arthritis and new advances in joint replacement techniques. He is a member of the American Academy of Orthopedic Surgeons, the California Orthopedic Association, and the Western Orthopedic Association. 

He received his undergraduate degree in Physiology at the University of California, Berkeley. Afterwards, he attended Boston University School of Medicine for his medical degree.

He then went on to complete both his surgical internship and orthopedic residency at University of California, Irvine. Following residency, he completed an additional fellowship year in joint replacement and adult reconstructive surgery at the Institute for Bone and Joint Disorders in Phoenix, Arizona.  

“Dr. Gorab has set the bar high for HOI in terms of providing world-class quality orthopedic care, and our clinical outcomes reflect his dedication for continuous quality improvement,” added Dr. Barnett. “His passion for high quality surgical care, clinical accountability and transparency in reporting clinical outcomes is a commitment I will work tirelessly to honor and uphold,” he said.
