Vitals review (Dr. Martin Greenfield)

"I have been a patient of Dr. Greenfield’s for 22 years. He is amazing!! I would not change him for the world. He is kind, attentive and always listens to my needs/concerns."

Birdeye review (Dr. Martin Greenfield)

"My mom could have died when her diabetic numbers were dangerously low, from too much insulin, and the doctor was not looking at her journal of daily readings. This went on for quite a while. He was not interested enough to pay attention."
