Doctor Flanagan is a doctor from God. She gave me calmness of my heart after I repeatedly had 3 small surgeries and one big breast surgery because of mastitis. Only she told me that in case it repeats again, this condition is treatable. It seems like in the whole clinic only doctor Flanagan is aware of various breast diseases and conditions. And she can treat them properly. I am thankful for her.

What a great doctor. She listens to you, and doesn't talk at you. Staff. How can I say enough nice things. Example. I called with a kind of an out of the box request. The staff knew me well enough that this was a red flag for them. They called back, got a family member, and sure enough, there hunch about me was right. Lets just say I was back in her office the next day, taking care of a dangerous complication. I had no idea it was really anything, but again, the staff really listens.
