Care Philosophy

This content was provided by Dr. Greenspan "I take care of people in pain. I am motivated to help my patients, to give them a better experience than others they have encountered, and to give them more relief and functionality than they had before they met me. There is a lot of emotion tied up with chronic pain: depression, anxiety, and guilt over not being able to fulfill their responsibilities. My patients tell me that I am a good listener; often, I am the first doctor who believed them when they said they were in severe pain."

I have learned to not see a doctor who owns his own practice. He only helps who he wants, profiles you as a drug seeker. i'm 25, and it was his idea to give me oxycodone and he just kept me on that for too long. my last office visit, I confronted him that I'm an adult and he only takes me seriously if I brought a parent or my boyfriend. and I'm 25... he should treat me as an adult. His staff mostly is nice especially the younger girls, but he is on a powertrip. DO NOT SEE HIM.

I would highly recommend Dr. Greenspan to my family and friends, and have. The number one thing I appreciate the most, Dr. Greenspan, is when you have an appointment at ( American Pain Institute), you will be seen by a highly knowledgeable doctor who listens to you and actually wants to help you....nothing less.

He is absolutely wonderful. I am petrified of needles and he completely understood. I barely felt the needle and he explains everything he is doing which I like to know and I think he truly cares and he listens. I have had some horrific experiences. I am never going to another doctor. Thank God for such a wonderful person. I highly recommend going to him. I know he is going to help me get rid of some of my pain. And he is highly intelligent which is awesome and he is funny. Thank you Doc! Elizab

I was discharged before my fourth visit. I was going weekly. I was discharged for not , repeat not taking my medicine lorazapram. I took my suboxone nut because I was weaning myself off, he discharged Mr. He has called withdrawal meds dome of which I never hesrd of. I would understand if I was taking something illegal buy I wasn't. Im very nervous of what's going to happen. I just don't believe it. All he had to fo us not prescribed it anymore.. I find this very distressing. I'm shaking now.

DO NOT GO to him. He puts you on very high dose pain medicine. Then finds a reason to drop you. And has is office people tell you not himself. The he sends some withdrawal medicine to a pharmacy that I never used at all while I was seeming him. Because he sent to the wrong pharmacy they couldn't check on interactions with my heart medicine that could of killed me.

I was seeing Dr Greenspan for back pain, during this time one of my pee test showed Morphine, at first I didn't know why, the next day I remembered that I was at a cookout and having a lot of pain, someone told me they had a pain med that was same as what I was on. I called her and asked her if it was Morphine, she said yes,(very low dose) DR Greenspan put me on probation but called on day of my appointment and said he wouldn't see me! Very unprofessional, I am 57 and do NOT abuse drugs,

Do not go to this Dr. He only helps who he wants to. His staff will laugh at you when you turn your back! The place is a joke!
