His light hearted manner matches perfectly for his professional care of hearts. I greatly appreciate his helping me overcome anxiety as an integral member of my health team.

I met Dr Sandler through my mom at the hospital while I was waiting for a procedure. He was so kind to me and my mom, she introduced me. I've been under his care for many years and I've never been disappointed he is genuine and a very good person as well as a Doctor you won't be sorry if you see him. He is caring, kind, compassionate, empathetic, professional, easy to talk to and go over your concerns, and he keeps track of you, you won't fall through the cracks. He listens deeply to everything you say and answers you like you matter unlike some other Cardiologists that I have had. What I really want to say is I highly recommend Dr Sandler and wouldn't go to anyone else!

I had a 3:45 appointment and wasn’t seen until after 5pm . Dr. Sandler however is attentive and personable and a great dr himself. The healthcare system in general however has to stop having them book only “15 min” appointments for patients and let drs schedule the appropriate time for patients so they aren’t kept waiting so long.
