Ithaca, NY |
Completely dismissive of issues and offered no path forward. The nurses were amazing and so supportive though.
Ithaca, NY |
Derogatory in a subtle way..doesn't spend time explaining plan.

Dr Brennan listened to my concerns regarding amount of anesthesia during previous colonoscopy. Made adjustments for this procedure by reducing amount and experience was improved 100%.
in Ithaca, NY |
He's very knowledgeable, and very pragmatic. If you talk to him, he will engage, so the key is to tell him your concerns. His treatments have always been consistent with what I am willing to try, he is quite open to finding a mutual path toward a goal.
