Love Dr. Agosto-Marquez! Will see her until the end of time!
She was kind and compassionate. She was thorough and listened and gave me options for treatment.
The doc came in -not my doc. I explained i thought i was here for hrt check and to go over my progrrss. Instead she seem to not want to deal with that & suggested I make an app with my real doc. ??? I agreed to the wellness check but not the papsmear (I already had one in January) they couldn't find the order results .During the pelvic examined the chaperone who came in, had a lap top , she never made eye contact with me , did not introduce herself, say hello, and stared at the wall. The entire time, except when she was looking at the computer very uncomfortable. I would rate her chaperone a 1. Over all i left in tears. Feeling aweful and never wanting to go back.
I had a great experience. Answered my questions and concerns.
