September 23, 2019 7:00 PM

I must be honest. I'm a procrastinator. I don't enjoy going to visit my doctor. But Dr Sullivan is a good doctor. I've been feeling very mental and physically drained for a couple of years. I decided that it was time to she her. I'm totally frightened of what I will find.

September 8, 2019 7:00 PM

I like Dr. Sullivan a lot. She explains things in a way I can understand it. She's a really good listener and I never feel like she's rushing to get to the next patient. She's responsive when I communicate with her via the portal and when I've left messages for her. Dr. Sullivan has helped me to improve my health. I hope that she will stay at the clinic permanently.

September 1, 2019 7:00 PM

August 23, 2019 7:00 PM

It was a short visit and my request was taken care of immediately

August 13, 2019 7:00 PM

Dr. Sullivan is competent and professional.

August 2, 2019 7:00 PM

April 19, 2019 7:00 PM

It was a very Visit what my provider.

April 19, 2019 7:00 PM

Provider exceeded my expectations, especially the speed at which I was able to get an appointment. Main purpose of visit was fractured collarbone.

April 10, 2019 7:00 PM

I went to this physician seeking a new primary care experience. She was attentive, knowledgeable, thoughtful and thorough. I will continue with her as my new doctor.

March 17, 2019 7:00 PM

have been a patient for more than 20 years

March 10, 2019 7:00 PM

She (my doctor) never treated me like I had knowledge on my illness. Never once did she showed empathy. She never answers any of my questions or gives me my results. I am done with her

March 10, 2019 7:00 PM

My health care prrovider is not very personable. Lacks care and concern..

March 3, 2019 6:00 PM

Dr. Sullivan brushed off my concerns about my knee injury. I feel that she did not thoroughly examine my knee. She stated that nothing was wrong and to continue normal activity when I could not put weight on my knee. The appointment felt very rushed.

February 26, 2019 6:00 PM

Dr. Sullivan is great. She always returns calls and gives personal attention. Best Doctor

February 25, 2019 6:00 PM

This was my first meeting with provider to establish a new PCP. Provider did not introduce herself at all during the visit. She asked " how can I help you". Provider did review medical history and ask I there were any questions. I felt like the provider just wanted to check all her boxes. the lack of interaction was very standoffish and there for has lead me to want to return to my previous provider.

February 22, 2019 6:00 PM


February 18, 2019 6:00 PM

Dr. Sullivan saw me on time . Listened to my concerns. Was very happy with my visit.

February 18, 2019 6:00 PM

excellent - trying to get my blood pressure under control - increase my dosage - follow appointment in month

February 17, 2019 6:00 PM

Very good.

February 17, 2019 6:00 PM

The office staff and Doctor Sullivan are always professional, kind and courteous! The lab technician on-site is the best ever!

February 16, 2019 6:00 PM

I'm in search for a great primary physician and used Advocate help desk to help me search for a provider that was close. I saw her rating after I made the appointment but still decided to try her out. I now see why her rating was 2 stars. She isn't warm, I really dont feel super comfortable coming back to her. I went in for chest pains and was scared because a previous doctor said nothing was wrong but my body said different. Although dr Sullivan provided me with an explanation, her delivery isn't warm for a patient who is nervous and scared. She ordered a UGI and one she got the results she had someone call me to tell me the diagnosis and to continue taking prescribe medication. I had many questions but the person she had call me wasn't equipped to answer them. I wasn't pleased with that so I emailed her. I told her medication wasn't working and asked about changing my diet. She ignored diet questions and said she would refer me to GI doctor. I paid my bill and most likely will not be visiting Dr. Sullivan in the future.

February 4, 2019 6:00 PM


January 29, 2019 6:00 PM

I love that Dr. Sullivan talks with my cardiologist Dr X. And they make sure I'm on the right medication.

January 29, 2019 6:00 PM

Dr. Sullivan is not the friendliest of people, but she gets to the facts, appears to be competent, and seems to have my best physical interest in mind. I see her to ensure my physical well-being, not because I need a friend, so it works out for us.

January 29, 2019 6:00 PM

this provider takes the time to listen to me, answer my questions and help me to understand my health status. She cares !!! I am grateful to have her as my doctor.

January 28, 2019 6:00 PM

Dr. Sullivan presents herself as too distant, emotionally and physically. Dr. Sullivan keeps her space she makes me feel as if I had a rare contagious illness.

January 27, 2019 6:00 PM

I thought the doctor was very nice and helpful. this was the first time seeing her.

January 26, 2019 6:00 PM

nice and clean medical office.

January 25, 2019 6:00 PM


January 24, 2019 6:00 PM

Very professional

January 24, 2019 6:00 PM

Over all, my PCP is very good with everything concerning my health and care and what is best for me. However, messages left for her nurse, do not get prompt attention. Sometimes it takes 3 calls to get her nurse to respond and once she does return your call, she is not courteous on the phone. She makes you feel as if you are bothering her with questions and or getting results for a test. when the pharmacy has requested a prescription for a refill it takes over a week or for me as the patient to get the prescription Iauthorized for a refill. There has been multiple times I have been without a prescription for the lack of response to the pharmacy. I always allow 24 hours for a response from the office, but that is not the case. I think this has to affect Dr. Sullivan's practice if her nurse is not following through with patient messages and test results.

January 20, 2019 6:00 PM

feels like i'm being tolerated

January 18, 2019 6:00 PM

I Like this Provider she seem very concerned when I addressed my problem and told me what I needed to do and followed up with what I needed to do.

January 15, 2019 6:00 PM

Always have a thorough visit with provider. She explains the steps for treating issue. Very informative.

January 13, 2019 6:00 PM

always professional and very courteous.

December 17, 2018 6:00 PM

I did not expect to be treated so rudely from an advocate dr. - Mary Sullivan.

December 16, 2018 6:00 PM

I suffer from anxiety which magnifies any illness I might have. Dr. Sullivan understands this so goes over everything me and is quick to reassure me when all is well she is very through, compassionate and an excellent physician.

December 1, 2018 6:00 PM

helpful , informative, very good. thank you all

November 26, 2018 6:00 PM

Main reason for this visit was to get my cholesterol results and a continuation of the cholesterol medication, which I had started 1 year previously. I spent most of the time with the CNA, who took my blood pressure, temp. etc. She seemed very dis-interested and really didn't listen to anything I had to say. Examples: told her I had received a flu shot, brought back in a consent for a flu shot. Asked for my lab results regarding my cholesterol numbers - gave me a lab result for blood chemistry, asked her to send the script for my cholesterol med to the mail order pharmacy - called it in to a CVS store (where my last script for an antibiotic was sent). Dr. visit was very brief.

November 26, 2018 6:00 PM

she listens to what I have to say

November 25, 2018 6:00 PM

Very good.

November 22, 2018 6:00 PM

She shows genuine concern for my issues and provides excellent referrals for other doctors when needed.

November 20, 2018 6:00 PM

I am happy with all my doctors with Advocate!

November 18, 2018 6:00 PM

Dr. Sullivan my primary physician is very professional and thorough; have been using Dr. Sullivan as my primary for a number of years prior to her joining the Advocate health system.I certainly would not have continued with Dr. Sullivan if I was not happy, obviously I am.

November 18, 2018 6:00 PM

Very sick with fever cough and she took great care of me.

November 15, 2018 6:00 PM

Overall good experience, most helpful overall.

November 15, 2018 6:00 PM

she have been my provider for a great many years I would not change her she has been very good and my health care and yes I would recommend her to any family and friends

November 12, 2018 6:00 PM

Dr Sullivan has been my provider for many years and I see her for my yearly checkup

November 12, 2018 6:00 PM

Very good, Thorough, I have had mild stroke and Dr. Sullivan has kept me on track. I am very pleased with all her care

November 11, 2018 6:00 PM

This was an appointment for an annual checkup. As always Dr Sullivan was very professional. She made sure I received my flu shot and pneumonia booster. Spent enough time with me so that I felt comfortable with the appointment and didn't feel rushed.

November 11, 2018 6:00 PM

the location is easy to get to, the facility is clean. the office staff are pleasant as well as the nurse taking my vitals. it is comforting to see the same faces when I visit. i am new to the clinic and thought highly of my previous PCP so I am working to build a relationship with dr Sullivan. I appreciate dr sullivan working with my cholesterol issues this visit. and my resistance to meds and giving me a short time frame to work on lowering my numbers

November 9, 2018 6:00 PM

Dr Sullivan is a compassionate and kind professional. She remembered things we discussed from my previous visit. She addressed a concern I had and explained it thought so she knew I understood. I Don't feel like just another number with Dr Sullivan.

October 17, 2018 7:00 PM

I thought this provider should have gone over my entire health history to get a complete look at all my medical needs and not just the urgent one. Seeing how this was my first visit with this provider.

October 8, 2018 7:00 PM

this is my new PCP and I think she is great so far.

October 7, 2018 7:00 PM

My husband, X, MD thinks so highly of Dr Mary Sullivan that when I needed an internist, there was no one else I would consider. She is a star in her field and the Advocate system is lucky to have her.
