Elevra Optimal Health is based in nearby Wentzville and treats patients throughout Dardenne Prairie by secure telehealth. There is no in-person clinic to walk into — in Dardenne Prairie or anywhere else in Missouri.
Elevra is a telehealth clinic. All care is delivered remotely by providers licensed in Missouri, and a provider-patient relationship begins only after a licensed provider has evaluated you.
Elevra treats testosterone replacement therapy for men, hormone therapy for women, medical weight loss, and peptide therapy — each prescribed only after lab work (where required) and a telehealth consultation, and only when clinically appropriate.
Dardenne Prairie is one of St. Charles County's fastest-growing cities. Wherever you are in Dardenne Prairie, care happens the same way: by secure telehealth, from a Missouri-licensed provider.
A free, no-obligation call to talk through your goals and how Elevra's programs work.
Baseline bloodwork at a lab near Dardenne Prairie — see options below — before your consultation.
A licensed provider reviews your results with you by secure video and, if appropriate, builds your protocol.
Elevra does not operate or partner with any lab. Baseline bloodwork is drawn at an independent draw site that accepts outside provider orders — once your provider sends your lab order, you can use any lab that works for you. Dardenne Prairie does not have its own Quest Diagnostics or Labcorp location; the nearest confirmed options are just over the city line in O'Fallon:
