What is Timeline Health?
Timeline Health is a functional medicine and hormone practice at 900 E. Hill Avenue Suite 205 in Knoxville, TN 37915. It is located inside Phoenix Spine & Health. Its main focus is hormone and metabolic care, with functional and longevity medicine built around it. Listed services include weight management with GLP-1 therapy, testosterone replacement therapy, bioidentical hormone replacement therapy, thyroid optimization, and perimenopause and menopause care. Peptide therapy is not listed as its own service.
Two prescribers are named. Charlotte MacDonald, DNP, FNP-BC is the founder, a family nurse practitioner with more than 14 years of experience. Dr. Richard Mays, MD is the medical director, a family physician who has been in private practice in Knoxville since 1978 and is board certified by the American Board of Obesity Medicine. Visits can be in person or by telehealth. In its own words: "Personalized root-cause, preventive, and longevity medicine focused on identifying and addressing the underlying causes of illness, preventing disease, optimizing health, and helping you thrive for years to come."
Office hours are Tuesday and Thursday from 7:00 AM to 3:00 PM and Wednesday from 9:00 AM to 3:00 PM. Friday through Monday is not listed. Google shows a 5 rating from one review, which is not much to go on. The phone number is (865) 333-3083.
What does it cost?
It does not publish prices. No consultation fee, monthly fee, or medication price appears anywhere. It does not say whether insurance is accepted. A Memberships link sits in the menu, but no membership fees or cancellation terms are published. The homepage lists "Transparent Pricing" among its values, so the missing numbers are worth raising directly. Ask for the consultation fee, the monthly cost of any program, and exactly what each one covers before you book.
What should you ask before you book?
Which prescriber will manage my care, Charlotte MacDonald or Dr. Mays? Does the monthly price include the medication? Which GLP-1 medication would I be prescribed, and is it brand-name or compounded? The clinic does not name one. Is peptide therapy offered? Charlotte's background includes it, but no program or price is listed for it.
What do follow-up visits and lab work cost, and are they billed separately? Does the clinic take insurance for any part of the care? How do I cancel, and how much notice is required?
Who is it a good fit for?
This is a good fit if you want hormone, thyroid, weight, or functional medicine care from a named prescriber, you plan to pay cash, and you are willing to get prices and medication terms in writing before you commit. It may not suit you if you need Friday or weekend appointments, since none are listed, or if you need to know the full cost before you call.
