“The only thing that sucked was going to the doctor’s office thinking I had an appointment but apparently zocdoc didn’t actually book my appointment? The doctor was sooo nice though & made time to see me. He listened, asked me questions & made sure to explain all the tests run on me & why we were doing those tests. Also the nurses were very nice, super helpful & made me feel comfortable. Definitely recommend! ”

My appointment was at 3pm I sat in the waiting room for an hour without being seen. I had to leave as I did not have time and expected to be seen at least within 15 minutes or provided an explanation. Would not recommend.
