What is Functional Health Clinic?
Functional Health Clinic is a functional medicine and integrative practice at 2101 West 41st Street, Suite 113, in Sioux Falls, South Dakota. Marsha Kadlecik, PA-C, established it in 2014, runs it as a solo practice, and is the only prescriber it names. It has a Google rating of 4 from 4 reviews.
Its main work is integrative cancer care, aesthetics and IV therapy. Weight loss is one of several services. The clinic lists a Weight Loss Program alongside alternative cancer treatment and consultation, the Galleri Test for early detection of multiple cancers, functional medicine consultation, acute care and pre-op physicals. Its aesthetic work includes Botox, fillers, platelet-rich plasma, stem cells, and CynoSURE and FlexSURE laser treatments. IV options include high-dose vitamin C, glutathione, B12 injections and the Myers Cocktail. It also lists prescriptions as needed and medical cannabis evaluation.
It does not list hormone therapy or peptide therapy. The regenerative options it names are platelet-rich plasma and stem cells. It names no weight loss medication. Visits are in person or virtual. In its own words: "In-person & virtual office visits (house calls available for many services)."
What does it cost?
It does not publish a price for the Weight Loss Program, and it does not publish a consultation fee. The one price it shows is for IV infusions, which start at $89. It accepts no insurance. In its own words: "All services are out-of-pocket." It does not say whether the program fee includes medication, and it does not publish a cancellation policy.
What should you ask before you book?
Ask who writes any weight loss prescription and whether that is Marsha Kadlecik, PA-C. Ask whether the program uses a prescription medication, and if it does, which one and whether it is brand-name or compounded. Ask whether the monthly fee includes that medication or whether it is billed on top. Ask what follow-up visits and lab work cost, how often they are needed, and whether the consultation fee is credited toward the program.
Ask which parts of the program can be done virtually and where you must be located for a virtual visit. Ask how cancellation works and whether a fee applies. If you want hormone or peptide therapy, ask directly, since neither is listed.
Who is it a good fit for?
This is a good fit if you want weight loss support inside a wider integrative practice, you are comfortable paying cash for every service, and you are willing to get the medication and cost answers before you commit. It suits people who want one provider for acute care, aesthetics and IV therapy. If you need a named medication or a published price, it is worth calling 605-201-4632 to get those answers first.
