Dr. Kolniak always comes to my annual physical thoroughly up to speed on all dimensions of my healthcare. She reads all the notes and reports of my specialists, and remembers well our previous discussions. She listens carefully, responds knowledgeably and on-point, and is compassionate. Like most patients, I always wish our chats could last a bit longer, but the time she's able to spend with me is never inadequate.
