Dr. Tennant graduated from high school at age 16 as class Valedictorian.  He went on to the University of Houston and completed his courses (except for 3 hours) in 2½ years He was awarded Phi Kappa Phi and the Pre-med-of-the-Year Award.

Following his stint at the U of H, Dr. Tennant next attended the University of Houston School of Optometry before he was accepted to UT Southwestern Medical School.  He completed his residency in Ophthalmology at Harvard Medical School/Massachusetts Eye and Ear Hospital and UT Southwestern/Parkland Hospital. Dr. Tennant is board certified in Ophthalmology and Ophthalmic Plastic Surgery.

He has served as Director of Ophthalmic Plastic Surgery at Parkland Hospital and Southwestern Medical School and was also the Founder/Director of the Dallas Eye Institute.

Dr. Tennant holds patents for intraocular lenses, surgical instruments, and several other medical devices, some of which operate on the holistic medicine principle.  He is the co-founder of the Outpatient Ophthalmic Surgical Society where he taught Ophthalmologists outpatient eye surgery in the 1980's.  He was one of first surgeons in the U.S. to place intraocular lenses into eyes after cataract surgery.  Dr. Tennant taught these highly innovative techniques around the world for several years.

Dr. Tennant is one of only a few ophthalmologists in the world to receive the Corboy Award for Advancements in Ophthalmology.   He also received the American Academy of Ophthalmology Award for contributions to ophthalmology. He has authored books on cataract surgery and lifestyle management.

Dr. Tennant has a history of changing paradigms.  He quickly learned that challenging the standard practice does not come without resistance however.  While serving as Director of the Ophthalmic Plastic Surgery Clinic at Southwestern Medical School/Parkland Hospital in the early 1970's, Dr. Tennant began placing intraocular lenses in eyes.  One fateful day in 1978, his chief said, "Anyone who is so dumb as to place lenses in eyes after cataract surgery has no business teaching residents."  Now, of course, it's almost considered to be malpractice not to put a lens in eyes after cataract surgery.

Dr. Tennant and his anesthesiologist, Dr. Monte Hellman, developed techniques for performing cataract surgery on patients coming in on an outpatient basis.  Several of the general surgeons and gynecologists complained that Dr. Tennant was taking up the prime operating times in the hospital.  They were accustomed to having those slots themselves and complained that what Dr. Tennant was doing was unsafe.

They said the patients did not have enough time to recover from the medications they were given for local anesthesia before they went home.  He continued to use his ground-breaking techniques.  This infuriated the general surgeons and Dr. Tennant was forced to open his own surgicenter.

He worked very closely with his colleagues, Dr. Douglas Williamson in Florida and Dr. David McIntyre in Washington, to get Medicare to pay for outpatient surgery.  Their efforts led to the approval of outpatient eye surgery which has saved taxpayers well over a billion dollars a year.

Dr. Tennant conducted a major portion of the research for the laser device used in LASIK surgery for the company VISX.  He performed 1,000 cases in the United States and 2,000 cases abroad.  It was a rewarding experience, but he accidentally inhaled some very serious viruses while doing the work.  At that time, nobody knew that the laser would not kill viruses.

The viruses from some patients' eyes went through Dr. Tennant’s mask and into his nose and brain.  He consequently developed viral encephalitis and a deadly bleeding disorder because the viruses he contracted caused his spleen to kill the platelets in his blood.

At that point Dr. Tennant was able to diagnose patients but couldn't remember how to write a prescription.  He also developed spastic movements that could cause obvious problems when operating inside the human eye.

At this point, Dr. Tennant felt he needed to stop practicing medicine before he injured someone.  He closed his office on November 30, 1995 and spent the next 6-7 years in bed, sleeping about 16 hours a day.  He had only a few hours a day of clarity before his mind would stop working and he couldn't even understand simple newspaper articles.

Dr. Tennant went to the best doctors he could find.  He saw the head of ocular immunology in Boston and the head of immunology for the NIH.  Eventually his oncologist said it was likely that Burkett's Lymphoma would develop.  As his blood profile worsened, it looked like he might die in the summer of 1999.

Integrative Medicine was first introduced to Dr. Tennant by his friend, Janet. She had received chemotherapy and radiation at M.D. Anderson Cancer Clinic in Houston for lymphoma and was told nothing more could be done for her. Janet went to Mexico seeking help.

While dining in a restaurant, Janet and her husband met Dr. Robert B. Vance from Las Vegas. Upon learning about Janet’s condition, Dr. Vance said, “Lymphoma is a piece of cake.” He suggested they come to his clinic for treatment. Janet initially declined but the tumor around her neck was choking her to death. She told her husband that if she lived through the night, she wanted to see Dr. Vance. After undergoing treatment from Dr. Vance, the tumors on her neck, left axilla, left kidney and spleen were all gone.

Janet sent Dr. Tennant photographic evidence of her groundbreaking treatment. He got out of bed and went to see how they had accomplished this. Her cure was affected primarily by removing the metal from her mouth, removing the mercury from her system, and giving her large amounts of electrons via IV Vitamin C.

Dr. Tennant had never heard of Energetic Medicine and asked if they would look at him. They quickly discovered what only Dr. Tennant knew at that point. He had a blood test just before he left Dallas that showed his kidneys were starting to fail (increased BUN and creatinine). They also found his tendency toward lymphoma, which he hadn't told them about either.

Learning about energy in the body became Dr. Tennant’s obsession.  As he began to understand more, friends came to his home asking for help.  He eventually transformed the uppoer portion of his home into a medical clinic.  When this became inadequate, he rented a room in a chiropractor's office and moved the operation out of his home. Eventually, he had two rooms in her office.

He expanded again to the clinic next door and finally settled in the larger clinic where he practices today.
