Multiple Patient Holder

Dr. Tennant holds over 13 patents for medical devices including intraocular lenses, surgical instruments and other devices including the Tennant Biomodulator® PLUS and PRO.


He was one of the first surgeons in United States to place intraocular lenses in eyes after cataract surgery and taught his technique around the world.

Master in Occular Surgery

A pioneer in LASIK surgery, Dr. Tennant was responsible for most of the research done on the Excimer laser for VISX. He also performed over 1,000 operations in the United States and about 2,000 cases abroad from 1991 to 1995.

Dr. Tennant’s Journey

Unfortunately, these numerous surgeries were the contributing factor to the decline in his health. In the early days of laser operations, it was believed that ordinary surgical masks were sufficient to protect doctors from contamination. Nobody suspected that viruses existing in a patient’s eyes could possibly harm the surgeon. However, each time Dr. Tennant performed surgery; the laser would strike the eye and release viruses that drifted upward through his mask and into his nose and brain. In time, he developed encephalitis and a bleeding disorder that manifested as spastic movements and an inability to remember even how to write a prescription. Diagnostic tests confirmed he had three viruses in his brain, but no one knew how to treat them. Dr. Tennant’s physicians told him there was nothing that could be done to help him. So, on November 30, 1995, he was forced to retire at the height of his career.

For almost seven years, Dr. Tennant was in a mental fog that rarely lifted. Too fatigued to function on any level, Dr. Tennant slept about 16 hours each day. During the two to three hours per day when he could think, he read books or newspapers until, like a light switch, his brain would turn off and he would no longer be able to understand what he was reading.

With his waking/thinking time severely limited, Dr. Tennant gradually began to realize that if he was going to get well, it was up to him to find a way since modern American medicine had no answers. So he started reading cellular biology books. As his knowledge grew, so did his belief in the importance of learning how to get a single cell to work correctly. If he could do that, in time, all of his cells would work correctly.

Each of the cellular biology books he read gave passing reference to the fact that cells function in a narrow range of pH, but said little more. Dr. Tennant began to look closely at pH. He came to realize that in addition to acidity and alkalinity, pH measures the voltage in a solution. Voltage. Could this be the key he was searching for? Gradually, Dr. Tennant began to understand that cells must have enough voltage to work and that chronic disease is associated with loss of voltage. His next step was to find out how to measure the voltage and keep it at optimal levels. Following this path, he was finally able to heal himself naturally.

Today, people travel from around the world to consult with Dr. Tennant at the Tennant Institute for Integrative Medicine. Dr. Tennant also teaches and lectures worldwide for Senergy Medical Group, the exclusive distributor of his patented Tennant Biomodulator® PLUS & PRO. These FDA accepted, non-invasive devices are designed to offer health care professionals and home users an affordable drug free and user-friendly options for the indicated use of symptomatic relief for chronic, severe pain and intractable pain; adjunctive treatment in the management of post-surgical and post-traumatic pain. The countless thousands of success stories and testimonials of patients’ recovery and pain reduction are phenomenal.

Dr. Tennant is the author of Healing is Voltage® The Handbook, Healing is Voltage® Textbook, Healing is Voltage® Healing Eye Diseases, Healing is Voltage® Acupuncture Muscle Batteries, Healing is Voltage® Cancer’s On/Off Switches: Polarity. These books are based on his own personal experience and continuous energetic medical research. Dr. Tennant’s objective, through his Tennant Principles, is to inform patients and practitioners how the body requires voltage to make new cells to maintain health and wellness, as well as incorporate traditional medicine with integrative medicine for better results.
