When I was recommended to Dr K my diabetes was out of control. Now I'm in a much better place. I would highly recommend her to anyone looking for a great doctor.

I have been a patient of Dr. Khalfin for several years. She is professional,knowledgeable and friendly. She takes time to answer any questions and I have never felt rushed. The staff is efficient,friendly and helpful. There were also occasions when I had questions about my prescription and texted Dr. Khlafin; she responded promptly which I really appreciated. I highly recommend this practice.

Dr Khalfin is the only endocrinologist that I’d ever recommend to my family and friends. She goes above and beyond to provide the best care for her patients. The office is also exceptionally clean, front desk is warm and welcoming. Can’t say enough great things.
