Orvin was born and raised near The Citadel in Charleston, SC. He decided to go to The Citadel and entered in September 1939. In his senior year at The Citadel he began medical school at the Medical College of Charleston as part of a government program to increase the number of doctors in the Medical Corps during WWII.
After graduating from medical school in May 1946 he went straight into the Army Air Corps as a flight surgeon trainee but was discharged due to a hearing impairment after a physical examination revealed scars on his ear drums.
After his discharge Orvin interned in New York City before returning home to Charleston and opening a general practice in 1948, which he ran for ten years. During this time he realized he enjoyed listening to patients and helping them with their problems. He trained in psychiatry, founded two hospitals specializing in the treatment of adolescents, and joined the Medical University faculty in Charleston.
Orvin discusses his time at The Citadel and his fond memories of the years he spent there. His love for his alma mater inspired him to create the Brigadier Club in 1948, which continues to raise money for Citadel Athletics.
