What My Patients Say

He has shown notable care for my recovery and has explained complex treatment choices to me such that I could make educated decisions. In the days, weeks and months after my release [from Washington Hospital Center], he monitored my daily progress and kept in touch with me to make sure I was doing well. He CARES and it shows! - AY

First visit with Dr. Ain and was very pleased. Having had Dr. Held for years, I had a lot of reservation about my new doctor but again, I say I made the right choice …. I am very pleased. - DG

Dr. Ain completely explained the procedure I was about to have and the options he was likely to have as the procedure went forward. He also was very welcoming to my husband and answered all his questions. After the procedure Dr. Ain not only gave me the wrap-up but also called me at home a few days later to assure I was doing well. His expertise, patient communication and concern were all exemplary. - GE
