What Our Patients Say
We could describe our care all day, but our patients say it best. Here is what people across Portsmouth and the Seacoast share about finding relief with Dr. Greenspan. Have a story of your own? We would love for you to leave us a review.
I tore three rotator cuff tendons in my right shoulder and was facing surgery after PT failed to help. Dr. Greenspan recommended stem cell injections instead. Eight months later, I'm back to doing pushups, reaching overhead, sleeping on that shoulder, and enjoying time in my wood shop again.
Chuck & EileenPatientStruggling with major back pain in your 20s sucks, but after going to several doctors and having injections into my spine to no avail, Dr. Greenspan has been a total diamond in the rough. The trigger point injections he performs have quite literally given me my life back, and he is so attentive and listens to your feedback on where you think might be best to inject. Highly recommend.
AllyPatientI've been a patient of Dr. Greenspan since 2014, and the care has always been exceptional. Dr. Greenspan and Kevin, the PA, are compassionate, thorough, and truly dedicated to helping their patients. The entire staff is professional, friendly, and caring. I highly recommend American Pain Institute.
