About O’Fallon 

With a population of just over 88,000 people, O’Fallon is a city located between Lake St. Louis and St. Peters and is a part of the St. Louis metropolitan area. The city has numerous attractions including the 9/11 Memorials and Veterans Memorial Walk. O’Fallon tourism is also centralized around the city’s many seasonal festivals, such as the Celebration of Lights & Old-Fashion Holiday Stroll, Food Truck Frenzy, Tree Lighting Ceremony, Heritage & Freedom Fest, and Founders’ Day. O’Fallon’s first settler was a German immigrant, Nicholas Krekel, and he settled here because his older brother purchased land that was partially donated to a railroad line. The city was officially incorporated in 1912 with 600 residents. 

Individualized Preventative Treatments in O’Fallon, Lake St. Louis, Wentzville, and Chesterfield 

At Ultra Wellness Medical, we get to the cause of underlying health problems rather than just treat the symptoms. We focus on providing treatments and assessments that detect disease states early and work with patients to make personalized treatment plans to maintain health.  As is always the case, medical care is a team approach between the patient, physician, and staff.  Our team uses prescription medications as part of our care plans when needed,  but Dr. Williams values a lifestyle approach where we educate you on effective habits you can implement, including sleep hygiene, diet, and physical activity, to support your health for years. 

Our offerings can help you enjoy a long and healthy life, whether you add IV and IM injection nutritional therapy to optimize your vitamin and mineral levels, choose bioidentical hormone replacement therapy to optimize your hormone levels, or shed unwanted pounds with medical weight loss treatment options, our team partners with you every step of the way.
