Mystic — The owner of a local medical spa is planning a multi-million-dollar expansion that will bring doctors from Boston and New York to Mystic as soon as next spring.

“We’re putting about $6 million dollars into it,” the owner of Cure Med Spa, Candice Georgiadis, said on Wednesday. “It’s going to be amazing.”

Georgiadis submitted a zoning amendment application last month that would expand the town’s definition of a medical clinic to include outpatient surgery, allowing the 40 Mason’s Island Road location to offer plastic surgery.

If approved, the medical spa would remain on the third floor of the three-story building across Harry Austin Drive from the YMCA.

The business would add a same-day surgery center and training facility on the vacant first floor and a day spa on the vacant third floor.

Georgiadis said that the Cure Institute surgical center on the first floor would consist of one surgical suite and a recovery room where plastic surgeons with various specialties would perform outpatient surgeries.

“We’re bringing in plastic surgeons from New York to Boston in their niche specialties, like someone who specializes in noses or someone who specializes in tummy tucks or body surgery specifically, which is very needed in our area,” she said.

She estimated that the surgical center would have 12 surgeons, six from New York and six from Boston.

“I’m going to be vetting them, and going through them with my team, and approving and making sure they are the best of the best,” she said.

The proposed training facility would be used to train practitioners on various treatments like Botox, injectable fillers, laser treatment or weight loss therapy.

Georgiadis described the second floor Cure Day Spa as high-end and said it would have amenities like hot and cold plunge pools, steam rooms, saunas and Vichy showers. The day spa will also have ability to offer more specialty services in conjunction with the medical spa on the third floor.

“The things we are putting into the day spa, no one has around here. It’s going be something like you’d see in Las Vegas,” she said.

Georgiadis said she doesn’t anticipate the changes will increase traffic or have any negative impact on the surrounding area.

The Planning and Zoning Commission has scheduled a public hearing on the application for Sept. 17.

If it is approved, Georgiadis hopes work can begin in October, and the center and day spa can open in the spring. More information on services is available at www.curemedspamystic.com.
