This service line includes over 50 laser, ultrasound, microwave, light based, radiofrequency, and radiation technologies, innovative local anesthesia cosmetic and reconstructive surgery techniques, a varicose vein treatment center, a full service dermatopathology laboratory, AAAHC Medicare-approved surgery centers, and over 41 providers that include board certified dermatologists, cosmetic dermatologists, laser surgeons, Mohs skin cancer surgeons, reconstructive surgeons, pathologists, a facial plastic surgeon, plastic surgeons, an interventional radiologist, and experienced nurse practitioners and physician assistants.

miraDry is treatment for underarm perspiration that delivers precisely controlled energy to the region where the underarm sweat glands reside and eliminates them non-invasively. Because the sweat glands do not regenerate following treatment, the results are long-lasting. Furthermore, patients can expect to see sweat reduction immediately after treatment, with minimal to no downtime.

If you’re close to your ideal shape, but need a little help getting there, Liposonix may be for you.

The average waistline reduction after just a single one-hour treatment is about 1 inch (2.5 cm) – which typically means one dress or pant size.

Consummate professional, absolutely exceptional in all areas of his work from complex MOHs laser procedures to cosmetic applications. Not the go-to guy if you need a psychiatric therapist more than a surgeon/doctor. There are lots of the former out there and only one Dr. Morganroth. If you want superior, world-recognized dermatological work, he’s the doc.
