In the operating room at Ogden Regional Medical Center, Dr. Calvin Reynold MacKay - better known as Dr. Ren - scrubbed up one last time to prep for surgery. It was a mock surgery, but a special day all the same.

Dr. Ren, 94, is a retired orthopedic surgeon. He graduated from the University of Utah and did residencies all over the country, including Seattle, New York and Louisiana. He served in the United States Navy and performed surgeries at three Utah hospitals: St. Benedict's (now Ogden Regional), St. Mark's, and LDS hospitals.
