"I recently had stem cells put into my thumb by Dr. Greenspan. It was a great experience. He is exceptionally skilled with the needle and I felt zero pain during the procedure."

"I have been going to Dr.Greenspan since 2014. He is one of the most caring compassionate doctors that I have ever met and very thorough he actually does his job and tackles the pain problems you have at hand he has done so much for me over these years I couldn’t ask for a better doctor. not to mention a few years back I broke my foot and I was having trouble getting the medicine that I needed it was late at night on his day off he answered the phone and he took care of everything for me not a lot of doctors do that kind of thing. So if you need help with your pain management and you’re open to all options American pain Institute is the place to go. I now see the physician assistant Kevin which is just as good as Dr. Greenspan I wouldn’t change my doctors for the World. Also everyone in the office is very helpful for professional and very nice. Thanks So Much for helping me in life with my care. You guys are the best!"

"I have been going to Dr Greenspan who is upfront about getting relief from the excruciating pain I was suffering from. The first three Epidurals did very little for me but the first one of the second round did the trick and I have been completely pain free for 6 weeks. I have to mention the ladies at the front desk are wonderful and caring. Dr. Greenspan is very gentle and I feel like I have my life back being able to do the everyday things. Thanks Doc"
