Verified listingAbout Dr. Mark Neumann
What is Dr. Mark Neumann?
Dr. Mark Neumann is a physician-run practice at 8140 Secor Rd in Lambertville, Michigan, serving the Toledo, Ohio area and nearby towns on both sides of the state line. It is primarily a functional medicine and wellness practice that also runs a medically supervised weight loss program, alongside testosterone therapy and peptide therapy. The practice has been open since 1981.
Mark S. Neumann, D.O., is listed as a prescriber and is a graduate of Palmer College of Chiropractic and the University of Osteopathic Medicine and Health Sciences, with a two year fellowship in Anti-Aging and Functional Medicine and a Diplomate credential from the American Academy of Anti-Aging Medicine. Jenna Klump, a Nurse Practitioner, is also listed as a prescriber. The weight loss program includes GLP-1 agonist prescriptions along with HCG injections and fat-burning injections, and the practice also offers cold laser treatments, nutrition counseling, and bioidentical hormone replacement therapy. Hours are listed only for Monday, Wednesday and Thursday, 9:00 am to 12:30 pm and 2:00 pm to 5:30 pm. Whether telehealth is available is not stated.
What does it cost?
No prices are published for any service, including the GLP-1 program, testosterone therapy, or peptide therapy. There is no stated consultation fee, and it does not say whether a monthly program fee would include the cost of medication. Insurance acceptance is not addressed. If you are considering this practice, ask directly for a full price breakdown before your first visit.
What should you ask before you book?
Ask whether Dr. Neumann or Jenna Klump would be the one evaluating you and writing your prescription, since both are listed as prescribers. Ask whether the GLP-1 medication is brand-name or compounded, and whether the quoted program fee, once you get one, includes the medication itself or is billed separately. Ask what lab work is required before starting testosterone therapy or a GLP-1 prescription, and what that testing costs. Ask whether insurance is billed for any part of the visit, including the office visit itself. Since the posted hours only cover three days a week, ask how follow-up appointments and refills are scheduled, and what the process is if you want to stop treatment.
Who is it a good fit for?
This is a good fit if you want a long-running, physician-led practice with a wide range of services under one roof and you are comfortable asking for pricing and medication details directly rather than finding them published online. It may be less of a fit if you need evening or weekend appointments, or if you want cost and insurance information settled before you ever pick up the phone.
