Dr OBrien was professional and pleasant. This was the first time seeing her. She inherited me from another doctor in their practice. She answered all questions. I would proudly refer her to anyone needing her services.

Dr. O'Brien never makes me feel rushed despite having what I'm sure is a very busy schedule, she always asks about me and my family and takes time to discuss treatment ideas and the reasons behind each. I truly feel listened to

Dr. O'Brien was the best provider I could've asked for. I had not seen an OBGYN in a few years because it was difficult for me to find a doctor like her. She met all the desires I had!
