He attended Oklahoma State University, receiving multiple degrees—biology major and microbiology minor as well as a business administration degree from a junior college—before moving on to Western University of Health Sciences in Los Angeles, California. His following three-year medical residency was with what he considered to be two of the best programs in the country—West Penn Hospital in Pittsburgh, where he was chief resident, and Swedish Medical Center in Seattle. He completed the first two years at West Penn and then applied and was accepted to Swedish Medical Center for his final year.

Dr. Peresko is an active researcher and a prolific author, having published upward of six papers in his final year of residency as well as authoring a textbook chapter.
