"The cure for anything is salt water."
— Isak Dinesen
Our Inspiration
At MerLeaux, our inspiration flows from the natural beauty of the coast — where the horizon meets the water and the world feels at ease. We believe wellness should feel like a breath of fresh salt air.
Our mission is to mirror that tranquility in our practice — providing a sanctuary where science meets serenity. We don't just want you to look your best; we want you to feel as renewed as a morning by the shore.
There is a unique healing power in the rhythm of the Mississippi Gulf Coast. At MerLeaux, we draw inspiration from the shifting tides and the golden light of Bay St. Louis. Just as the sea rejuvenates the shore, our treatments are designed to restore your natural glow.
Our Team
Every member of our team brings decades of clinical experience — and a personal understanding of the wellness journey — to every patient interaction.
David F. Roberts, MD
Board-Certified Family Medicine Physician
Board-Certified Family Medicine Physician
Dr. Roberts is a board-certified family medicine physician with more than 35 years of clinical experience on the Mississippi Gulf Coast. A graduate of the University of Mississippi School of Medicine with residency training at the University of Tennessee's Jackson-Madison County General Hospital, he has long served patients through Memorial Hospital at Gulfport and community clinics in Gulfport and Diamondhead.
After personally losing 120 pounds under medical guidance, Dr. Roberts developed a strong focus on metabolic health. He now leads MerLeaux's medically supervised weight management, hormone optimization, and wellness protocols with deep understanding of both the science and the emotional journey of weight loss.

What We Stand For
These aren't just words on a wall. They're the clinical and ethical standards that guide every decision we make on your behalf.
Every treatment is physician-supervised and follows the highest clinical standards and regulatory compliance. We never cut corners — your safety is the foundation of everything we do.
We believe informed patients get the best results. We explain every treatment, every step of the way — so you walk in with confidence and leave with clarity about your care.
We don't chase trends. We use proven, FDA-cleared technologies with measurable outcomes and follow-up care — because your results should last long after you leave our doors.

Rooted in the Gulf Coast
MerLeaux was born from this community. We are your neighbors, your friends — and we are deeply committed to bringing world-class aesthetic medicine to the Coast, without the drive to New Orleans or Biloxi.
Our Commitment
At MerLeaux, every treatment protocol is developed and overseen by Dr. David Roberts, our board-certified Medical Director. We do not offer treatments that haven't been vetted for safety, efficacy, and regulatory compliance.
We believe the most powerful tool in aesthetics is an educated patient. That's why we built our entire Education hub — so you can understand exactly what each treatment does, how it works, and what to expect before you ever sit in our chair.
From our "Know Before You Glow" treatment guides to our procedure video library, we are committed to transparency at every step of your journey.
Physician-Supervised Protocols
Every treatment plan is reviewed and approved by Dr. Roberts. No treatment is performed without medical oversight.
FDA-Cleared Technologies Only
We exclusively use FDA-cleared devices — including the Lumenis Stellar M22, TriLift, and OptiLight — because your safety demands nothing less.
"Know Before You Glow" Education
Our comprehensive treatment education library ensures you understand every procedure before you commit — no surprises, no pressure.
Personalized Follow-Up Care
Your treatment plan includes follow-up care and check-ins. We track your results and adjust protocols to ensure lasting outcomes.
In Their Own Words
Hear directly from patients whose health, confidence, and wellbeing were transformed by the MerLeaux team.
"I was nervous walking in — I'd never been to a med spa before and wasn't sure what to expect. Within five minutes, Mary had me completely at ease. She listened to every concern, never made me feel silly for asking basic questions, and put together a plan that fit my budget and my goals. No pressure, no upselling. Just genuine care. I've since referred four friends and every single one has had the same experience."

"I drove from New Orleans specifically to see this team and it was 100% worth it. The ResurFX treatment cleared up years of sun damage. The facility is immaculate, the staff is warm and professional, and the results are real."

"Best med spa on the Gulf Coast — hands down. The OptiLight treatment for my dry eyes was life-changing. I had no idea a med spa could help with that. Dr. Roberts and the team are exceptional. I tell everyone I know about MerLeaux."
