He offers all clients a complimentary consultation to decide what treatments are right for you.

Dr. Greenberg envisioned a spa enhanced by the benefits of combining medicine and science. After hearing horror stories about patients being burned and scared due to unsafe treatments, he realized the necessity of having complete supervised services. He recognized this dream by opening Skin Thera PTM located in New York City on 301 E. 81st, where luxury treatments meet technology and science in a comfortable and medically driven setting.

Dr. Greenberg graduated magna cum laude from Tufts University in 1983 and then attended New York Medical College where he earned a medical degree in 1987. Dr. Greenberg received postgraduate training at Lenox Hill Hospital in Manhattan and went on to practice medicine.

  • At Skin Thera PTM you can correct sun damage, fine lines, and wrinkles with an assortment of anti-aging treatments that are performed or overseen by Dr. Greenberg.
  • Reversing the signs of aging is the first step towards maintaining a youthful appearance.
  • All of our facial treatments, masks, and peels are performed with pharmaceutical grade products, which have a direct biologic effect on your skin. Skin Thera PTM also specializes in medical grade, scientifically based Cosmeceuticals that work together with your treatments in an effort to continue to make your skin look its best.
  • In addition to our own skin care line we carry brands such as Obagi, SkinMedica, Neocutis, Remergent, and others.


Skin Thera PTM is designed to offer safe, medically supervised cosmetic treatments such as laser hair removal, photo facials, Botox, Restylane, Radiesse, Cosmoderm, microdermabrasion, and glycolic acid facials. When a client’s skin is in the right hands, results can be both gratifying and empowering. Although when put in an unsafe environment, the results can be detrimental to not just your skin but also your well being. With the sudden popularity of medical cosmetic treatments, patients have been scared and burnt due to unsafe procedures offered by unsupervised, non-medical spas. Medical supervision is not a luxury, but a necessity for safety and efficacy.
