I provide personalized, thoughtful care. I take each patient seriously, I listen carefully, I review diagnostic possibilities and treatment options with you, and we develop a healing plan.
I particularly enjoy helping patients with complex medical problems. Initial internal medicine visits typically last at least 45 minutes. More complex cases may require a 2-hour initial visit.

"When I came in for my first visit, I was so sick that I had given up hope of ever living a normal life again. Thanks to Dr. Greenfield, I feel I am well on my way back to being myself again.
Dr. Greenfield has been wonderful in listening to my story, figuring out what was wrong, and defining a treatment plan which has made all the difference. He's incredibly thorough, thoughtful, careful, and caring. I finally feel like I have an advocate in the healthcare system.
Give the doc a call; you won't regret it. "
