Providing Family Medicine and Primary Care services to O'Fallon, Lake St. Louis, and Wentzville areas. The Goal of Ultra Wellness Medical is to provide exceptional, comprehensive medical care for patients, with access to your doctor who knows your health and is in tune with your individualized goals. Dr. Michael Williams will work with patients as a team to provide education and to develop a customized plan for treating the root of illness rather than symptoms. Ultra Wellness Medical offers same-day patient appointments to members through visits to the office, by phone, or telemedicine when necessary. Our goal is to make access easy and provide time within each visit to make sure your questions are answered.
