I started going to Dr. Sparks because he was upstairs from my old office but have stayed with him even after we moved offices. He has a friendly staff (including his wife who works there). I've been seeing him for the last 5 years and since then my wife and her family (6 people) all see him for their general maladies. As an osteopath he looks at your complete health when diagnosing problems and deciding whether to refer you to a specialist. The office is modern with all of your records available on a touch screen computer and he has testing equipment and x-ray machines in-house, which is convenient. His no-nonsense approach and willingness to answer questions directly is appreciated.
He does what he can to fit you in at the last minute and interestingly, almost all the specialists in Dallas know him and think he's great. He takes almost every kind of insurance as well.
