Dr. Lemole received his undergraduate degree from Villanova University in Philadelphia in 1958, and doctor of medicine degree from Temple University School of Medicine in 1962. From medical school, Dr. Lemole returned to his birthplace, Staten Island, N.Y., where he served a one-year internship at Staten Island Hospital.
Upon completing his internship, he returned to Philadelphia for a residency in general surgery at Temple University Hospital. He did his cardiac training at Baylor College of Medicine in Houston, Texas from 1967 to 1969, under the direction of Dr. DeBakey at Baylor and Dr. Denton Cooley at the Texas Heart Institute.
Dr. Lemole became certified by the American Board of Surgery and the American Board of Thoracic Surgery and began serving as an instructor in surgery. In 1968 he was a member of the surgical team that performed the first successful heart transplant in the United States.
Dr. Lemole returned to Philadelphia from Texas in 1969 as an instructor in surgery at Temple. That same year he performed the first coronary bypass in the tri-state area of Pennsylvania, New York, and New Jersey. At age 32, he was named Chief of Cardiothoracic Surgery at Temple University. He was Chief of Surgery at Deborah Heart & Lung Center, Brown Mills, N.J. from 1972 to 1984. In 1975, at age 38, he became a full professor at Temple – an achievement which also made him one of the youngest full professors of surgery in the United States.
