Great office, great staff, amazing doctor!

Skilled Doctor, beautiful office, great service. Couldn't ask for a better experience!

Wonderful professional experience. Dr. Halsey and his staff are so nice. I never felt embarrassed.Office very clean.Covid precautions followed.

Is it weird that I love this place? Probably, but how can you not? I have visited this office two times already and my first impression I was blown away. Angela was the first to greet me... extremely helpful and sweet. took me through there COVID protocols. Then Dr. Mark Halsey came in with his lovey assistant Emma. So helpful and made me feel so comfortable I wanted to stick around for a cup of coffee afterwards. Dr. Halsey even called me later that day. This whole office deserves a lot of praise. Just so everyone that is reading this is clear. I don’t write reviews I don’t even know if this is the right way to write a review. But in the past month I’ve visited an Amazing dentist and an amazing dermatologist. If they went out of their way to help me out and be so friendly how could I not tell everyone about my experience. PS I still hate Yelpers. Is it weird that I love this place? Probably, but how can you not? I have visited this office two times already and my first impression I was blown away.

Dr. Halsey and his staff provide a flawless environment for dermatological care. The space is immaculate. They always work on time. The generous nature and professionalism of his staff is unmatched. My daughter saw him for a bit of an emergency appointment and felt so well cared for. My husband and I then went for full body skin scans and were very happy. I went on to see him for laser treatments for sun damage and I’m so appreciative of his kindness and patience and willingness to see through on what I need.

Dr Halsey is personable and explains everything well. He is also very easy to reach if there is a question. The staff is also very personable and efficient

Dr Halsey s office is well organized and everyone was prepared for my visit. The staff is professional and friendly. Dr Halsey was thorough in his check up and answered questions in a very informative way. I felt confident in his diagnosis. I will return for my yearly check up, even though I have a dermatologist in New York.

The stuff very nice

My wife and I went in for a general check-up, knowing nothing about Dr. Halsey. He turned out to be very friendly, gracious, unhurried, and informative about the condition of our skin. His office is brand new, super clean, and furnished with impressive-looking equipment. Staff is most friendly, welcoming, and helpful.
