The entire staff from the front desk to to doctor is awful. NEVER GO HERE! Terrible bedside manner. They had me and my 1 yr old daughter waiting forever, then when they finally saw my daughter, they rushed through her appointment.The doctor was not showing enough concern towards my 1 year old. She did not do a good job at physically examining her before making an assessment.

I had a terrible experience at this drs office. I made the appointment through zocdoc and had verified that my insurance is accepted. Upon arrival the extremely rude and unprofessional staff claimed that my insurance isn't accepted. I advisedthem my insurance was verified prior and accepted. The staff made a phone call and then did confirm my insurance is accepted but then they wanted a higher co-payment than what my insurance requires and had no reason why. Not only was the staff extremely rude they wasted my time. I would not recommend this office to anyone.

Actual visit with Dr was shorter than the time I sat in the waiting room to get called to a room. However all that I stated I was having issues with was not addressed I felt pushed off and rushed withno interest the Dr didn’t even notice I was pregnant not because you aren’t an OB but you’re still dealing with patients. Apart from the medical assistant sneezing like crazy the Dr claim she was congested she was sniffling all over me nose running boogers in her nose I was just disgusted. Overall I didn’t fell welcomed nor comfortable and I won’t be returning.

The doctor was courteous and efficient. She was attentive to my complaints and concerns, diagnosed my condition after a brief but thorough examination, administered a relatively pain-free injection for my skin condition, and advised a plan for a course of treatment.

It was a pleasure to see an office so efficiently run. The staff was congenial. I was seen on time which is a first for me in a long time. Dr. Hammerman and her staff were so attentive and I feltthat my condition was taken seriously and than addressed fully. Everything was explained to me in a concise and respectful manner. I felt at ease, not talked down to or rushed. I would definitely recommend Dr. Hammerman to my friends and relatives.

I arrived a few minutes early and the front desk staff were friendly and welcoming. There was a bit of a wait to see the doctor, but I wasn't in a rush, so it was fine. Things went downhill when Imet with the PA, who didn't even bother to look up from her chart to greet me or even to ask questions. Dr. Hammerman came in a few minutes later and she was even more cold and clinical- there was no warmth to her face. As a first time patient, you'd expect to feel a bit welcomed.She did a cursory exam , and sent me on my way. Would never used thisbpractice again. I'll stick to Spring Street Dermatology, even if it's a bit of a trek to lower Manhattan.

Showed up early, but was seen immediately. Most of the paperwork was done online when I made the appointment, so checking in for first time was a breeze. Very friendly, helpful staff. Doctor was professional, and quick, without making me feel rushed.

It was a great experience. I took my child and she treated her right away. I had taken her to other dermatologists that did not do anything to her and Dr. Hammerman was awesome. :)

Love the service I was in and out and the doctor took enough time to explain everything she needed too. The only con I have to say is leaving the credit card on file and it being manditory. I've been tooher doctors office and work for one and I always seen that it was optional not mandatory. They should really let patients decided if they want to keep their credit card on file for 90 days.

Filled out all my paperwork online, so that definitely helped! Apt was for 4:10pm. Waited about 20 minutes. Was seen by an assistant first. Waited in the room for about 5-8 minutes. Met with Dr. Hammerman. She was very helpful withthe diagnosis (eczema). Recommend a few medications and tests that can be done. Requested a follow up soon. Was with her for about 5-10 minutes max. Out by 4:50pm. Would recommend! :)
