About White Onyx Functional & Aesthetic Medicine
What is White Onyx Functional & Aesthetic Medicine?
White Onyx is a medical practice in Gardner, Massachusetts, with one office at 354 Main Street, Unit 5, Gardner, MA 01440. The clinic calls itself a functional medicine practice first, with aesthetic treatments offered alongside. Its prescriber is Dr. Elizabeth Tateoka, DNP, whose title on the clinic's site is Functional Medicine Nurse Practitioner.
The clinic offers functional medicine, bioidentical hormone replacement therapy (BHRT) using the Biote Method, medical weight loss through its Root Cause Reset program, and peptides. Its aesthetic services include Daxxify injections, dermal fillers, microneedling, chemical peels, laser hair removal, and IV hydration and vitamin injections. It also offers telehealth visits to people anywhere in the US. On medical weight loss, GLP-1 therapies may be incorporated when clinically appropriate, as one tool within a broader plan. In its own words: "Weight loss is rarely just about willpower." The office is open Tuesday through Friday from 10 to 6:30 and Saturday from 10 to 4, closed Sunday and Monday, and works by appointment only. Google users give it 4.9 from 73 reviews.
What does it cost?
The clinic charges $99 for a 45-minute initial consultation covering weight loss, hormone optimization, or functional medicine and wellness. That $99 can be applied toward a same-day purchase. Aesthetic consultations are listed as no cost.
White Onyx does not take insurance. It accepts HSA and FSA payments when eligible, and it offers financing through CareCredit and Affirm. It describes itself as a certified CareCredit provider.
It does not publish prices for weight loss programs, hormone therapy, peptides, or aesthetic treatments. Ask for those figures before the first visit.
What should you ask before you book?
Ask who writes any prescription and whether Dr. Tateoka follows you through the plan. It does not name the weight loss medications it prescribes, so ask which ones it uses and whether each is brand-name or compounded.
Ask whether any program fee includes medication. Whether GLP-1 medication is included in any price is not stated. Ask what follow-up visits, lab tests, and lab reviews cost, since testing is central to its approach but its prices are not listed. Ask how to cancel a program and whether the $99 consultation credit applies if you do not continue. If you plan to use CareCredit or Affirm, confirm the treatment you want is covered.
Who is it a good fit for?
This is a good fit if you want a practice that starts with a functional medicine evaluation and lab testing, and you are ready to pay out of pocket, through HSA or FSA, or with financing. It is a poor fit if you need a firm total cost for weight loss or hormone therapy before you book.
