Everyone was so sweet, I am so happy I found a doctor who listened to me and understood what I was going through my whole life without hesitation, can’t wait to see her again with progress!

I have been to two other doctors and this by far was the best. She asked questions, listened to me, answered all my questions was calm and explained everything. She was amazing

It wasn't clear that the Drs office was located inside the urgent care office. So I was nervous I would get sick in the waiting room, but I was quickly moved to their side of their office which was strange but ok. While my visit was a waste of time and the dr. did not want to help me with any of my allergy issues, she was just pleasant at most. Her nurse was pleasant as well. Maybe this dr needs more of an office space to better assist and help patients. Either way, I will not return.
