I want to thank my doctor for listening to my concerns and making me feel comfortable during my exam.

Dr. was amazing as always. I live about an hour away but choose to take the drive instead of finding local office because I love this office.

That is all.
September 08, 2022
Overall service was great. Just the process and the waiting period for an authorization approval, just takes way too long, I'm still waiting and haven't heard anything back from the office or just to get a courtesy call would be nice to let me know that the office is being processed and they will let me know when I get the proof. I mean, I don't know what happens next.

The doctor did a great job. She was there to listen and she explained everything down to the point. I would definitely go ahead and recommend her a million times to anyone.

Dr. Mercurio was very kind, patient, and explained everything really well. She also took her time and was gentle when she checked me for my 38 week OB visit. I appreciate her.
August 02, 2022
My situation was explained with detail and very thoroughly. I appreciated that Dr. Mercurio made sure I understood everything she was explaining and didn't make me feel like it was being rushed. Thank you so much.
July 27, 2022
First visit with this doctor and she couldn't been better.
July 27, 2022
I feel like my doctor was rushed. I didn't feel like she cared about my concerns.
July 22, 2022
I don't like gynaecology visits because of trauma with prior medical professionals but Dr Mercurio was very kind and professional. Definitely deserves a raise.

July 15, 2022
I like that she really listens to you and what I like the most that she got back with me on the phone to tell me that it was nothing wrong and she took the time to listen to everything I had to say and she explained everything very carefully. Thank you.
June 28, 2022
I have seen Dr. Mercurio twice in the past month or two. She is very professional and friendly and put me at ease. No one enjoys going to the OBGYN. She was very easy to talk to.
June 20, 2022
My visit with Dr. Mercurio was excellent from start to finish up, starting with the people that were at the front desk. They were also kind and put me at ease and I had a really, really good experience even just being checked in and Dr. Mercurio so very trustworthy. She listened to me. She explained all my options me and it was an excellent experience and I will definitely be recommending it to my friends.
June 15, 2022
Dr greeted entering the door , there was no eye contact till we were face to face . Impersonal for first time visit. Dr needs to allow patient to speak. Dr needs to Listen carefully and then give feedback. Only after getting frustrated did she stop and try to listen . She could have checked my chart to gather info. My concerns were almost repeat from previous appointments. Only agreed to see this physician because (name removed) had no appointments. Will not return to this physician.
June 15, 2022
Doctor was friendly and knowledgeable yet very professional and thorough. The staff was also great. I'm very satisfied.
June 10, 2022
This was my first prenatal appointment for my first pregnancy. I was disappointed that at no point during the appointment did Dr. Mercurio ask if I had any questions. I had brought a list of just a few questions (which all friends and pregnancy websites recommended I do) and I never got to ask them. She did give a lot of information, but it was just verbal and when I left I had trouble remembering exactly what she said. I think knowing that someone is experiencing pregnancy for the first time in their life, it is reasonable that they would have questions for their doctor.
June 02, 2022
I was very impressed with the staff in the reception area. And I was also impressed with the doctor, whom I had never seen before. She was very attentive to my questions and took care of me immediately. I'm very grateful to have gone to your facility. Thank you.
June 02, 2022
my c section was supposed to be scheduled at 39 weeks, but the dr. said just cause its a holiday weekend she did not want to schedule it and she was covering the weekend. She advised since my 3rd surgery, she did not feel comfortable doing on a weekend let alone a holiday and pushed me to another dr. at 39.5 weeks. I did not feel taken care of but felt like an inconvenience. Dr. Mercurio felt rushed and she could careless.
May 20, 2022
Office staff and doctor was very nice and talked and if I had any questions and if I had other issues I need them to know. I was very impressed.
May 19, 2022
Thank you to all the staff and Dr, you all made me feel so comfortable. Dr listen to me and addressed all questions I had.
May 10, 2022
Dr. Mercurio is a excellent physician and she truly cares for each of her patient. Dr. Mercurio listened to my concerns and addressed each one carefully with her wealth of knowledge and expertise. We feel reassured with her being one of our physicians as we look forward having our baby at PIH.
May 10, 2022

I wasn't pleased with Dr Mercurio's visit. I have been seen by other Doctors in the past and I had the most pleasant experience except with this particular Doctor.
December 17, 2021
To long of a wait in the waiting area 45 minutes
December 17, 2021

November 19, 2021
Everything went smoothly and explained very nicely.
November 18, 2021
I've never felt so comfortable and not judged by a female provider dealing with women issues ever until now! . We're already uncomfortable talking about what goes on down there but doctor made me feel comfortable enough to explain my issues and not embarrassed. Thank you so much!
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
Hi, my name is [PHI removed]. I just wanted to give feedback on when I left the doctor's office. I was leaving and I have my two grandkids. So I was kind of irritated by the time I got out of there, but I had asked the doctor to give me a doctor's note and I never received it. So I got all the way to my car and realized that I didn't receive the doctor's note for work. So, I went back up there inconveniently, asked the front desk and she said that she can't take care of that. She has to see if the girl hasn't left to lunch yet. So I told her well, can't you just email it to me? And she says, no, I can't. I have to ask a certain girl that gets that. And the certain girl wasn't there. So I took it upon myself to go to the back before she even came back and asked the ladies back there. And they all gave me attitude because I guess they were going to lunch. I don't know what the situation was, but it was hard just to get my doctor's excuse and it made me very upset because I didn't get it in the first place.
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.
November 11, 2021
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.
November 08, 2021
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.
November 05, 2021
Dr. Mercurio was awesome! She made me feel comfortable and had a way of settling me as I was deepen concerned w/my medical condition. I appreciate her
November 04, 2021
Dr. Mercurio is extremely pleasant and very down to Earth; she makes me feel very comfortable and is very informative in everything she does. Thanks again Dr. Mercurio!
November 02, 2021
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.
November 01, 2021
Very nice and friendly. Spent plenty of time with me and explained things well. Didn't feel rushed
November 01, 2021
Very kind provider. Spent time to get to know me and speak with me during our visit
October 19, 2021
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.
October 18, 2021
I appreciate that dr Mercurio didn't make feel bad since I was returning for my same complaint...issue.
October 14, 2021
Thank you for making me feel comfortable and heard.
October 13, 2021
I was very happy with their response. They made me an appointment right away that was taken care of right away, I didn't have to wait a long time, the receptionist, we're very courteous. The doctor was very, she was able to explain everything. So simple for me. It wasn't difficult to understand what you were saying, and she was very kind. I would I would recommend her or somebody else if I have to. Definitely. Bye.
October 13, 2021
Dr Mercurio is hands down the best doctor I've ever had. She takes the time to really listen to my questions and concerns and always responds thoughtfully and thoroughly. I am so thankful to have found her!
October 07, 2021
I felt like I was not heard throughout the appointment and felt like the doctor was trying to rush and didn't listen to what I said. She was being rude
October 05, 2021
Great experience altogether.
October 01, 2021
Dr. Mercurio was very professional. Very friendly. Very understanding. Confidential. Very... she seems very knowledgeable, and I was very happy with her. She even called me on a Sunday to give me my results. Imagine that she is the best. Thank you.
