New Program at Tennant Institute Addresses Fatigue

by Sheila Julson

While everyone can occasionally feel fatigued, a constant lack of energy or overall feeling of tiredness could be more than just simply not getting enough sleep. That led the team at the Tennant Institute to introduce their new Fatigue Program, a customized energy reset package that includes methods such as the Tennant BioModulator, a non-invasive, drug-free device that uses voltage to relieve chronic pain. The device was invented by clinic founder Dr. Jerry Tennant, who studied how low voltage, or energy, in the body interferes with reproduction of healthy cells, thus leading to other health complications.

“The reason we decided to go ahead and implement this program is because there are a lot of people out there that struggle with just fatigue. It’s very difficult to diagnose and treat, but we understand what’s going on is that there is an underlying issue of voltage,” says Shellie Pruden, manager of the Tennant Institute. “By being able to correct that, and to figure out what’s causing the voltage issue in the first place, we can see great progress with treating most forms of fatigue.”

Dr. David Smithson, a physician at the Tennant Institute who specializes in the Fatigue Program with Dr. Chase Faldmo and Dr. Amy Marshall, notes that overwhelming fatigue is a symptom of many categories of illnesses, such fibromyalgia or chronic Lyme disease. “Those people are just devastatingly tired all the time,” he says. “We think the core problem here is to find out the cause of why people have low voltage, and then we can correct it and give them some new tools to get better.”

The doctors begin with a thorough physical exam and a detailed medical history to learn about any past medical issues. Patients are then tested for their voltage levels. “That’s our baseline—how much energy do people have?” Smithson explains. “Once we get a baseline, we have to figure out why those people have such low voltage—and fatigue is really another word for low voltage. There are five main things that Dr. Jerry Tennant has identified as to why people can have low voltage—low thyroid hormone function; dental infections; scars; toxins; or emotions. Usually, it’s a combination of those things.”

The Tennent Institute team uses innovative techniques to uncover the reasons for low voltage, including heavy metals testing for toxins and clearing out blocked emotions that can lead to depression and other signs of mental fatigue. The doctors also do a dental check for oral infections and check thyroid function. 

“Once we have a good baseline and know what we’re dealing with, we can use oxygen and intravenous (IV) therapy to help increase the body’s voltage. We also give patients tools to use at home to continue to get their voltage up,” Smithson says. “That includes the Tennant BioModulator, because that’s a good way to recharge and re-attain voltage.” The device is distributed through Tennent Institute’s sister business, Senergy Medical Group. 

Smithson adds that while there are many clinics treating low energy and fatigue, unless the body’s voltage is corrected, he feels those people have very little chance of getting substantial long-term benefits to feel vibrant and healthy and stay that way.

“We meet people every day that don’t feel well, are always tired and have tried conventional therapies, but mainstream doctors just don’t have information as to why someone feels a certain way because it’s out of their ballpark of traditional healthcare,” concludes Jerry Gutierrez, executive vice president of Senergy Medical Group. “People say they feel tired, yet their bloodwork seems to be okay, and they get prescribed antidepressants or medication. But we take it to a natural level to try to help with something different.”

Tennent Institute is located at 35 Veranda Ln., Ste. 100, in Colleyville. For more information, call 972-580-1156 or visit
