5/5
I was looking for a new primary care doctor and found one with Dr. Siddiqui. From the time I called for an appointment his staff was friendly and fast answering the phone. I received my appointment within 2 weeks. He took his time, and explained everything. I think I was their for a good 30 minutes just talking and going over my history 5 STARS!!!!!
