Dear Judy: While I am unfamiliar with Dr. Ron Alterman, I did ask Dr. Lieberman about him and he said that Dr. Alterman is "very good". I hope this helps you in your decision. Best of luck!

My mother is comtemplating DBS surgery of the type where the Medtronic device is the one used, along with the bilateral implants. Does anyone on the list know a neuro surgeon named Ron Alterman MD. He is on the staff of Beth Israel Hospital in New York City. All input greatly appreciated. Thanks. Renee part/time cg for Judy (75, 65, 63)
