Dr Rosenthal is a native of Savannah and was educated in Savannah’s public school system. He attended Armstrong College and the University of Florida prior to accepting early entrance to the Medical College of Georgia in Augusta. At MCG he served as President of the Student Honor Council, was recipient of the Dean’s letter for academic excellence and won the prestigious Sheard-Sanford Award for meritorious original student research. Upon graduation, he completed his internship in Medicine at Piedmont Hospital in Atlanta and his residency in Ophthalmology at the University of Alabama Hospitals and Clinics in Birmingham, where he served as Chief Resident. Following his residency he spent two years in the United States Navy at a regional Naval medical center, primarily for the treatment of wounded in Viet Nam servicemen from all branches of the Armed Forces. While there he served as Chief of Ophthalmology and attained the rank of Lieutenant Commander.
He returned to Savannah in 1971 and was in the solo practice of Ophthalmology for twenty two years before joining the Georgia Eye Institute, where he has practiced since 1993. He was a pioneer in bringing phaco-emulsification cararact surgery to Savannah and the Low Country, as well as introducing, along with his friend and colleague Dr. Richard R. Schulze (Retired), clear corneal, no stitch, no injection cataract surgery to Southeast Georgia and the South Carolina Low Country. Dr. Rosenthal was the first eye surgeon in either Georgia or South Carolina to insert a foldable intra-ocular lens implant at the time of cataract surgery, thus ushering in the era of true small incision cataract surgery to the region.
