Patient Reviews

November 12, 2021
Great conversation, I felt listened to and valued
November 12, 2021
Dr. Mercurio is always so personable. She takes the time to understand my problems and involves me in coming up with a treatment plan. I'm so happy to have her as my doctor!
November 11, 2021
Excellent experience with the doctor yesterday. She's wonderful in all ways and has a ton of knowledge. I enjoyed my visit.

It is upsetting that I am no longer treated like a patient, like a person due to my vaccination status. I never said I was against the vaccine but that I needed to get to my 6months of pregnancy for my own state of mind. Her only recommendation was to get vaccinated and showed no regard for the anxiety, stress, and panic I feel. She basically compared the pregnant nurses that have to work under worse Covid exposure as if we are all the same. Different people handle things differently. My mental health is different from others and It is very disappointing to have my own doctor show no empathy and be so dismissive.

They calle me to vefify my insurance the wk prior to my appt, I gave them all my information. When I got there it was a mess, nobody knew what was going on with my insurance. They were telling me I wasn't active when I had the information in my phone. At the end they figured out it was a mistake on their part for not putting in my insurance information correctly but first they made me sign a waiver for their mistakes. Not first time this happens.

I have never felt so comfortable at a "women's check-up appointment." The doctor put me ease with her friendliness during the exam and really took the time to listen to my concerns and give me some valuable feedback. I really appreciated the time she spent with me. Thank you.

The provider was excellent in listening and explaining. I used to have Kaiser which was for the most part, an unsatisfactory experience. So seeing this new provider was a relief to actually be listened to and not rushed off.

Thank you very much.

July 28, 2021
The doctor that I saw was great and very thorough. The only thing was that she seemed to be in a rush. I know that she has to see lots of patients but if she could slow down just a bit. I felt like she was just trying to get the appointment over with as quickly as possible. Again, she answered my questions completely and explained everything in great detail. But if she could just slow down a bit. Thank yo

June 15, 2021
Hi, I'd like to talk to her. She, she seems to know what she's doing. She was just really pressed for time because her previous appointment ran over because of something that had come up. During that appointment, but she apologize for running late and it'll. I felt comfortable with her. This is my first time with her. So, I definitely will go back next year for another appointment. So thank you. Bye-bye.

Yes, the response time for setting up appointments, they put you on hold for at least 30 minutes before you get someone to make an appointment. So that time should come down a 30 minute hold call just to make an appointment. It's just not acceptable.
February 01, 2021
Very positive visit
January 21, 2021
Dr. Mercurio was a great physician and she delivered my baby boy. I highly recommend her to anyone.
January 20, 2021
The time that it took to be service was great. I would just recommend that the front desk staff here make eye contact as when I did check in they were not making any eye contact and it took awhile for us to connect. So I would just encourage the receptionist to look up my eye contact and welcome patient that they're walking in but everyone else was awesome. Once we once I was able to speak to receptionist and she was able to look at me and connect with me the experiences a lot better. She's very friendly. It was just that initial engagement everyone else like the back office staff the doctor. They were all very very great. I really enjoyed my experience.
