“Dr Gantwerker is fantastic and his office staff, Annick and Helene, are absolute gems. So far each step has been quick, clear, easy and helpful. Annick and Helene are personable, friendly, fun and with wonderful humor!!
Dr G is very kind and very thorough. Prior to him, no other MD had done a thorough and comprehensive physical exam of me - which seemed odd. Dr G did. And he showed me my MRI and explained it in detail. I have been very scared about what's happening with me, and after meeting him, my fear is actually gone (may it stay gone) and I feel taken care of.
Don't hesitate to see Dr Gantwerker, he's excellent. ”
