Dr. Tennant graduated from high school at age 16 by finishing his junior and senior years simultaneously in 1957. He finished college (except for three hours credit) in 2 1/2 years at Texas Tech University. He was awarded the Phi Kappa Phi and Pre-med of the Year Award.
He attended the University of Houston School of Optometry and was accepted into the University of Texas Southwestern Medical School in 1960 at age 19. He graduated in the top ten of his class in 1964 with an MD degree. Dr. Tennant interned at Methodist Hospital of Dallas and then completed a residency in ophthalmology at Parkland Hospital in Dallas and Harvard/Mass Eye and Ear in Boston. He is also a fellow of the American Society of Ophthalmic Plastic and Reconstructive Surgery. Dr. Tennant was director of the Ophthalmic Plastic Surgery Clinic at Parkland Hospital/Southwestern Medical School and founded the Dallas Eye Institute.
He holds patents on surgical instruments, intraocular lenses and other devices and has written books on cataract surgery, life-style management, and Integrative Medicine. With the assistance of his anesthesiologist, Monte Hellman, MD and his internist, Javier Ramirez, MD, Dr. Tennant developed and refined the techniques to allow eye surgery to be safely performed in an outpatient setting instead of a hospital.
Along with Drs. David McIntyre and Douglas Williamson, Dr. Tennant founded the Outpatient Ophthalmic Surgery Society and taught surgeons around the world to do outpatient eye surgery and was instrumental in getting Congress to pay for outpatient surgery, saving Medicare millions of dollars every year. He was chairman of the ad hoc committee that wrote the rules that govern outpatient surgicenters in Texas. Dr. Tennant is one of the few surgeons to be awarded the Corboy Award for Contributions to Ophthalmology and the Recognition Award from the American Academy of Ophthalmology. Dr. Tennant was one of the first surgeons in the U.S. to place intraocular lenses in eyes after cataract surgery, eliminating the need for thick, incapacitating glasses after cataract surgery. He redesigned the European lenses to eliminate defects and was awarded patents for his designs.
