Dr. Gillis' Wellness Center Review

The verdict: a doctor-led walk-in clinic in central Maine

Dr. Gillis' Wellness Center is a small walk-in clinic in Oakland, Maine that prescribes GLP-1 medication for weight loss. It is built around in-person care: new patients enroll by walking in on a Wednesday afternoon with printed forms, and staff can give your weekly injection in the office. The site mentions telehealth too, but it describes the reach two ways: 'throughout Central Maine' on the homepage and 'nationwide' in the FAQ. Treat it as a local clinic first and call to confirm before planning around remote care.

Prices start at $149 a month for an oral GLP option, which lands a little under the category median of $179. The injectables cost more: semaglutide from $200 and tirzepatide from $300 a month. What you're really paying for is a named, board-certified physician and free follow-up visits rather than a faceless national platform.

How we get the category median: $179 is the middle value of the cheapest ongoing monthly price (not a first-month promo) at each of the 508 GLP-1 providers we track.

How the pricing actually works

The structure is simple and posted on the clinic's own site. Oral GLP therapy starts at $149 a month. Injectable semaglutide starts at $200 a month, and injectable tirzepatide at $300. Paying cash takes $25 off either injectable, and consultations and monthly follow-up visits are free. There are no contracts, and you can choose weekly, bi-weekly or monthly injection plans.

Be clear-eyed about what those numbers represent: they're starting prices. The clinic doesn't publish what higher doses cost for any of its medications. As your dose climbs over the months, which is how GLP-1 therapy normally works, the bill may rise. Ask directly what you'll pay at maintenance doses before you commit. The advertised price is a floor, not a ceiling.

The medications

The core menu at the clinic is semaglutide (the molecule in Ozempic and Wegovy) and tirzepatide (the one in Mounjaro and Zepbound), both as injectables. The oral GLP option is offered from $149 a month, but the site doesn't name the molecule, and the clinic doesn't state in writing whether each product is compounded or brand-name either. At these prices they are almost certainly compounded, so ask before you start your first dose.

One item deserves a clear warning. The clinic advertises a retatrutide add-on for $100 a month on top of semaglutide or tirzepatide. Retatrutide is an investigational drug still in clinical trials, and it is not FDA-approved for any use, and there is no approved version for a clinic to prescribe. We would not add it to your treatment, and its presence on the menu lowered our trust score for this clinic.

What genuinely sets it apart: a single accountable physician

The clinic is built around Dr. Gillis personally. He's a board-certified physician and surgeon with more than 25 years of experience in gut health, hospital privileges at MaineGeneral and St. Mary's, and a seat on the Maine State Medical Board. In a market full of anonymous prescriber networks, a named, credentialed doctor attached to your care is a meaningful signal. If you value knowing exactly who stands behind your treatment, that's the draw.

• Free visits — consultations and monthly follow-ups cost nothing
• An oral option — for patients who would rather not inject
• A real, named physician — board-certified, 25-plus years, sits on the state medical board
• No contracts and same-day starts — with in-office injections if you want them

Who should choose it — and who should skip it

Choose it if you live near Oakland, Maine and want a single accountable doctor you can see in person. The free follow-ups and no-contract plans also suit people who want to ease in cautiously.

Skip it if you live far from central Maine and need a fully remote service. Skip it if you want FDA-approved brand-name pens billed through insurance, because the clinic doesn't take insurance. And skip it if full dose-by-dose pricing is a dealbreaker, since only starting prices are published.

Trust, safety, and what's still unpublished

On the positive side, there are no FDA warning letters against this clinic, and the physician credentials are strong and specific. The gaps are real, though, and the retatrutide add-on is the biggest one, since it puts an unapproved drug on the menu. The clinic doesn't publish a state licensing list, describes its telehealth reach inconsistently, and doesn't spell out compounded-versus-brand status for each medication. Settle those questions at your first visit. You can see how we weigh these factors in our scoring methodology.

Bottom line

Dr. Gillis' Wellness Center is a credible, fairly priced, doctor-led choice for people in central Maine. You get free consultations and follow-ups, a named physician, and starting prices from $149 for the oral option. Go in knowing that those are entry rates and higher-dose costs aren't published. Confirm whether your medication is compounded, and decline the retatrutide add-on. For a local patient who wants an accountable doctor down the road, it's a reasonable, human-scale alternative to the big national platforms.

For a side-by-side, AgelessRx ($139/month) and Gala ($149/month) are the most comparable options to weigh against Dr. Gillis' Wellness Center.
