About Me

What I Do at MSK
  • Director, Dermatologic Surgery, Hauppauge
Get To Know Me

I am a dermatologic surgeon who specializes in caring for people with basal cell carcinoma, squamous cell carcinoma, and early-stage melanoma, as well as other rare forms of skin cancer.

As Director of Dermatologic Surgery at MSK Skin Cancer Center Hauppaugue, I lead a team of skilled physician assistants, nurses, patient care technicians, and laboratory staff providing high-quality skin cancer care to residents of Long Island.

The main focus of my practice is dermatologic surgery to remove skin cancers as well as skin reconstruction. I completed fellowship training in dermatologic surgery, and have particular expertise in a technique called Mohs surgery. Mohs surgery is an excellent option for people with nonmelanoma skin cancers located in delicate areas of the body. It has an extremely high cure rate and offers excellent cosmetic outcomes.

I believe that high-quality skin cancer care is compassionate and comprehensive. To me, this means not only curing the disease, but paying close attention to my patients’ personal preferences, comfort, and quality of life. I am grateful for the trust that patients place in my hands when they choose me for their care.  

With more than 20 years of experience, I continue to be fascinated and curious about the field of dermatology. I am constantly looking for new ways to enhance the techniques I use to treat patients, whether that means refining an existing approach or developing a new one.

My specific research focus is on sophisticated optical imaging devices called reflectance confocal microscopy and optical coherence tomography. These state-of-the-art technologies are not in wide use today, but in the future they may offer a noninvasive alternative to skin biopsy and help guide other aspects of skin cancer management. MSK’s Dermatology Service is at the forefront of this leading-edge technology and I’m proud to be a part of it.

My Role at MSK

A dermatologist is a doctor with special training in skin, hair, and nails.

A Mohs surgeon is a doctor with special training in treating skin cancer with Mohs surgery. This surgery removes cancer while keeping healthy tissue safe.
