After graduation, Dr. Constantine moved to Oakland, CA and worked as a medicinal chemist for Chiron Corporation synthesizing small organic molecules to be used as potential anti-cancer therapies. His work resulted in being named on four patents. Despite his enthusiasm for basic science research Dr. Constantine found that he missed the joy of treating patients directly.
Hoping to combine his love for basic science and improving human health, Dr. Constantine spent nine years earning both his MD and PhD at the University of Utah in Salt Lake City. It was during his graduate training that he began to develop his love of ophthalmology and, more specifically, the retina.
Upon completion of his medical school and graduate school training, Dr. Constantine completed his intern year in internal medicine at the University of Utah and then transitioned to Durham, North Carolina where he completed his ophthalmology residency at the highly regarded Duke Eye Center.
He finished his two-year vitreoretinal fellowship at Sierra Eye Associates, which allowed him to combine his two passions: Taking care of patients and participating in research. In addition to his clinical and surgical training he was a sub-investigator on many clinical trials.
Dr. Constantine is very excited to join Orion Eye Center and to provide compassionate care to the residents of central Oregon. He enjoys spending time with his wife and two boys and they are excited about all that central Oregon has to offer. In his free time, he can be found biking, skiing, and climbing.
