After discharge from the military in 1919, Dr. McIver moved to Jacksonville in 1920 to practice general medicine and urology with his uncle. In 1935 he limited his practice entirely to genitourinary surgery. He was one of the earliest urologists in Florida. He developed a preceptor program which evolved into a residency program in urology at the Duval Medical Center and at St. Vincent=s Hospital in Jacksonville. He was a consulting surgeon in urology at Flagler and East Coast Hospitals in St. Augustine, and the Veterans Administration Hospital in Lake City. In 1948 he founded, with Dr. VanNortwick, Dr. Newman, and Dr. Brown, the Florida Urological society. A past president of the Florida Medical Association, Dr. McIver became President of the Southeastern Section of the American Urological Association in 1948. Dr. McIver was a member of the Florida State Board of Health, founded the Jacksonville Blood Bank, and was an outstanding community figure for many years. In 1965 Dr. McIver was presented with a Certificate of Merit from the Florida Medical Association for outstanding service to the medical profession.

Dr. McIver has been described by many as an eminent medical leader with a national reputation as a speaker, teacher, and surgical technician. Visitors and patients came from all over the world to see him and to be under his care. He was a very gregarious and extroverted individual. Dr. Tom Palmer, a retired pediatrician in Jacksonville, described him as Apersonality plus, and had he been parachuted to earth over darkest Africa, within minutes of landing he would have occupied a position at the chief=s right hand.@ Dr. Leo Wachtel, a general surgeon, described Dr. McIver as being Aa real surgical technician who was the kind of doctor that he wanted to have participate in any surgical care that he might have.@ Most of the early training in urology was under a preceptor type of arrangement. In fact, Dr. McIver founded the McIver Urological clinic under this principal. He would often give surgical demonstrations. In 1941 he presented a surgical demonstration to the entire Southeastern Section of the American Urological Association.

Dr. Herman Brooks followed Dr. McIver to Jacksonville in the late 1930's. Dr. Brooks had trained at the University of Georgia Medical School and in New York City. He would later become chief of urology at St. Luke=s Hospital in Jacksonville. In those early days, Dr. McIver owned his own urological equipment. This served both to give him excellent equipment and to also control those individuals who wanted to invade the practice of his specialty. It was in this period of time that Dr. Antonio, a Philippine physician taking a residency at Johns Hopkins Hospital, came to Jacksonville as a preceptor under Dr. McIver. Dr. Antonio later became the president of St. Thomas Medical School in Manila. During these years, the President of the Philippines came to Jacksonville to have surgery by Dr. McIver.

At the end of World War II Dr. William VanNortwick, who had trained at the University of North Carolina and at Vanderbilt University, came to Jacksonville. He entered the preceptorship and finished the urology training, which he had begun at Watts Hospital in Durham. When he completed his residency, Dr. McIver asked him to join the McIver Clinic. Dr. VanNortwick assumed responsibility for the residency program for many years until it was absorbed by the University of Florida.

Dr. Elijah Thomas Sellers did medical urology and worked in Dr. McIver=s office for a number of years. Dr. Sellers had been an general practitioner who became interested in urological care. Like other medical urologists he primarily spent his time doing office urology, then encompassing primarily the treatment of venereal diseases, urethritis, and strictures. It was at the point of Dr. Seller=s retirement in 1965 that Dr. Stokes joined the McIver Urological Clinic.

In the late 1940's Dr. Robert Brown from Statesboro, Georgia, took his residency at Duval Medical Center and then joined the McIver Clinic. He was called into active military duty to go to Korea, but returned to Jacksonville after the Korean conflict to become active in all aspects of medical care. He was very concerned with the hospital organizations, in particular St. Vincent=s Medical Center. Dr. Brown=s contributions, until his death in 1976, centered around his kind, gentle, manner and his ability to understand the situations as they occurred. Dr. William Hutchinson, a general practitioner in New Jersey, came to Jacksonville and took his residency in the late 1950's. He joined the McIver Clinic in 1959, the third partner in the group at that time. Dr. Hutchinson=s primary contribution to urology was the development of the ureterovesicoplasty and the promotion of pediatric urology.

Dr. Stokes joined the McIver Clinic as the fourth partner in 1965. He had come to Jacksonville in 1961 after getting out of the Navy. He trained at Bowman Gray Medical School and Grady Hospital in Atlanta before finishing his residency at the Duval Medical Center.

The residency program at the Duval Medical Center (which later became University Medical Center) was managed primarily by Dr. Willam VanNortwick after Dr. McIver=s retirement in 1959. Dr. VanNortwick continued overseeing this program until the late 1970's. It was taken over by Dr. Charles Lewis (whose son Richard now practices with the McIver Clinic), a retired Navy Captain who trained in urology in San Diego. The residency program was finally transferred to the care of the University of Florida College of Medicine and totally dissolved in 1985.
