Dr Hosseini was phenomenal. She took what is a very scary situation for me and my family and brought a level of education and calm that we very badly needed. She was kind, informed, and clearly an expert in her field. Exactly the kind of care you hope for. As she described the procedure we will undergo, I started to feel lightheaded, nauseas, etc. She stuck with me and my wife, gave us options, and most importantly, instilled a level of confidence in me that I am going to be ok. Thank you!

This provider was exceptional. We showed up for the appointment. The provider had to be in emergency surgery and didn't show up for an hour and a half. [redacted] When the provider came, she had all the knowledge that she needed, took all the time necessary. Even though she was having an awful day, an excruciating day, she did not hurry the interview whatsoever. She took every question. She would have gone on as long as we needed to. Absolutely exceptional. I can't say enough about her demeanor and how she handled this.
