Fitness guru calling himself Dr. Dave, registered as health care provider now faces sentence for fraud of $3.9 million

David Williams called himself Dr. Dave and claimed he served clients in Las Vegas, Denver, Orlando, Seattle and Tucson.

In reality, he is a fitness expert from Fort Worth, has been charged by federal authorities with fraudulently billing health insurance companies more than $25 million and billing for medical services while impersonating a certified healthcare provider. He was arrested in October, and a jury convicted him Wednesday on four counts of health care fraud, each count punishable by a 10-year prison sentence and a $250,000 fine. Williams is scheduled for sentencing in August, according to a news release from the U.S. Attorney’s Office Between November 2012 and August 2017, Williams advertised on his website,, that he could deliver in-home fitness training and therapy through his company, “Kinesiology Specialists,” the release said.

On a website, he told potential clients he accepted most health care insurance coverage plans. In order to bill insurance companies for his services, Williams registered as a health care provider with the Centers for Medicare and Medicaid Services, according to federal authorities.Williams falsely certified that he was a health care provider on his applications to federal authorities, according to the release. Using different names or variations of his name and his company names, Williams enrolled as a health care provider at least 20 times and falsely certified that he was a health care provider in each application, the release stated.

Williams billed insurance companies as though he were a medical physician and as if he had provided care requiring complicated medical decision-making.

What Williams actually provided was fitness and exercise training to his clients, the release said.

Williams used flyers, the internet and word-of-mouth to recruit potential clients, according to the release. Williams would typically meet with or speak with a new client by phone and review their health history and goals for their planned fitness training, the release said.

Usually, Williams would assign a personal trainer to the client. Then the personal trainer would meet with the client between one and three times a week for approximately an hour and provide fitness training.

Williams would then bill insurance companies for each training session using inaccurate codes and sometimes would bill for services that neither he nor his staff provided, the release said.

He was paid more than $3.9 million stemming from his fraudulent billing of United HealthCare Services, Inc., Aetna, Inc., and Cigna.
