How likely are you to recommend Dr. Greenstein?

(Select your rating)
Dr.Greenstein is a sweetheart! Before dialysis, my doctor was actually Dr. Greenstein’s boss, Dr.Steer, head of the Balboa Neperoloigy group. I was not happy to learn I had to switch doctors then, but I quickly found from the groups surgeon Dr. Brown, to Dr Greenstein, Dr.Steer understood having caring & skilled doctors in his group. Greenstein’s group at the Escondido office,takes great care of their patients in every way. I would be very upset now to lose Dr Greenstein. I highly recommend him
