Dr Firshein is a gem in today’s age. I felt like he really listened to me and cared to understand what was going on. He asked many questions and did a deep dive into my history. Not dismissive at all. Nice office and all the other staff were great. Probably one of the first doctor appointments ever where not only did I not have to wait to be seen but they called me in before my appointment time!
