He later received a Bachelor of Science in Medical Technology from Old Dominion University and trained further in blood banking and HLA immunology. This training allowed him to work closely with the kidney transplant program at Eastern Virginia Medical School. A DDS was earned at Virginia Commonwealth University in 1987 followed by a General Practice Residency at the Medical College of Virginia Hospitals. Ralph has over 40 years exposure to all facets of transplantation. The last 25 were focused on allograft use in dentistry. Currently, he has “the best job in the world” – retirement.
