Dr. Nisi & staff are always friendly & respectful to my family.

July 22, 2020 3:44 PM

Visit went well. Was a regular routine yearly check up. New blood work and recommended shots given (tetanus, shingles). Also discussed colonoscopy procedure to be done soon.

July 22, 2020 3:44 PM

The experience has been very good since I started with this group. I needed a primary physician and am very satisfied with the level of care and follow up. I also really like having all my medical information available on line under the Advocate Aurora Health Portal. I also felt very safe at the office as well as the blood work facility.

July 22, 2020 2:50 PM


July 21, 2020 9:08 AM

The doctor is always very direct, lets me know what is going on with my health. Very thorough with blood work

July 20, 2020 10:45 PM

Dr. Nisipeanu is very thorough. she takes the time to understand what is going on, and she makes sure that I understand exactly what to expect. I never feel rushed and I feel very cared for.

July 20, 2020 7:50 PM

Very helpful and respectful, good listener, very pertinent advice regarding my health. Answered all my questions. I have been with my last pup for about 10 yrs and I had thought he was great. Dr. Nisipeanu is way better, I felt very comfortable discussing my health issues. looking forward to the next visit.

Dr. Nisi is a very good, pleasant, friendly & thorough provider.

May 13, 2020 8:34 AM

The only negative I have is when calling the office & having to go through the answering group to get a message to office is a nightmare - so now I only email & that's perfect.

May 9, 2020 1:53 AM

the doctor is always courteous, respectful and open to listen to your issues.

March 30, 2020 8:35 PM

Good experience. What I would expect.

March 30, 2020 8:35 PM

The answering service kept me waiting for 6 hours to make an appointment. I had to call back repeatedly. I finally walked in to the doctor's office without an appointment. I was treated right away.

March 30, 2020 1:38 PM

very approachable and will provide you lots of health information

March 30, 2020 1:20 PM

I always enjoy seeing Dr. Nisipeanu. She is so understanding and eases my mind. I try to see her when I can't get into seeing my regular GPC

March 21, 2020 11:23 AM

Always a pleasure to be seen Dr. Nisipeanu. She always pays attention to my concerns, and is always very thorough in my care.

March 17, 2020 4:40 PM

My experience with Dr. Nisipeanu was exceptional. I am very apprehensive about going to the doctor and even worse if I have to be hospitalized. She put me at ease and made me feel comfortable in the exam room.

March 17, 2020 4:40 PM

Good experience with Dr. Nisipeanu! I almost look forward to going to the doctor now!

March 14, 2020 7:16 AM

Very good doctor.

March 12, 2020 10:05 AM

Dr. Nisipeanu & her staff are exceptional. Always pleasant, happy & helpful. Recently moved back to Illinois in Nov. of 2019 & couldn't have found a better primary physician.

March 10, 2020 10:32 AM

Dr. Oana is very kind and good in what she does.

March 9, 2020 10:35 PM

great place

March 9, 2020 10:35 PM

friendly environment

February 25, 2020 12:53 PM

you could never ask for a better Dr. then Dr. Nisipeanu!!!! She listens, she examines, she asks your opinion, she's kind and she never rushes you!!!! So glad I am a pt. of hers.

February 25, 2020 12:53 PM

The whole staff is exceptional!!!

February 24, 2020 7:00 PM

always easy to talk to

February 24, 2020 5:48 PM

Dr. Nisipeanu is the best doctor that I have ever had attende. She figures out what is wrong with me, how it could be treated, and what specialists would be the most helpful.

February 24, 2020 5:48 PM

Dr. Nisipeanu has improved my quality of life. I am so much happier now than before she started treating me. I am also able to do more physically.

February 20, 2020 11:38 AM

Is excellent and professional.

February 17, 2020 11:02 PM

I was happy with the provider and how she paid attention to what I had to say and took my concerns seriously.

February 11, 2020 10:57 AM

I was called for a follow-up from a November appointment and the doctor did not know why I was there to see her. ???????

February 11, 2020 10:57 AM

I had to wait an unusually long time in the exam room before the doctor was ready to see me.

February 10, 2020 3:20 PM

This was my first time seeing Dr. Oana and I thought her whole staff was really accommodating and friendly. They were very personable and I felt like they were really wanting to help me get better. I was seen quickly - the nurse that took my vitals was super personable and friendly, and then Dr. Oana and her shadowing Dr. Assistant were very attentive to listening to all of my concerns. I am considering leaving my previous Dr. office (Dr. X) to come to this office - they were definitely more personable and they are closer to me!

February 10, 2020 2:35 PM

cannot directly call the provider so you must call and left message with someone at the help desk. tried that a few times and did not get a call back from doctor staff

February 10, 2020 2:35 PM

so there really was limited follow up by provider staff

February 10, 2020 1:44 PM

This was my first visit with Dr Nisipeanu, I found her to be very nice, thorough and knowledgeable.

February 3, 2020 1:54 PM


February 1, 2020 2:30 PM

Staff and doctor were professional, kind, helpful, and accommodating.

February 1, 2020 2:30 PM

Always good. Never a bad experience.

February 1, 2020 11:52 AM

Thought the exam was rather brief.

January 27, 2020 1:36 PM

The nurse and Doctor acted very professional and I would recommend them to anyone.

January 20, 2020 10:20 PM

My PCP provider is Dr O Nisipeanu, is very good. Very informative. Listens to my questions and concerns. I love going to her. Office staff very nice and friendly. My visit is in and out, very happy with Dr Oana and look forward to seeing her.

January 20, 2020 8:24 PM

I like her very much, she cares.

December 30, 2019 1:02 PM


December 23, 2019 3:09 PM

dr nisi is a great pcp

December 23, 2019 3:09 PM

December 9, 2019 9:15 AM

It was my first visit with this new doctor. I was very worried but the doctor was great. She talked to me and was very nice. She informed me on lots of things.

December 2, 2019 5:05 PM

she is a wonderful doctor

December 2, 2019 5:05 PM

she always gets me in when I call

November 25, 2019 2:09 PM

I always have a good experience when I go to see my doctor.My doctor really listen to me when I talk to them. And they reassure me of any concerns that I may have.And they talk to me and explain to me anything that I may not fully understand. My doctor is very thorough on appointment's,tests,or specialists.

November 22, 2019 9:49 AM

Every time we see our provider, we have a good experience with her and the office and workers is very respectable.

November 22, 2019 9:49 AM

Never had a bad experience.

November 20, 2019 3:28 PM

I'm very comfortable & satisfied with this provider.

November 17, 2019 11:00 PM

I feel confident that Dr Nidipeanu has my my best interests concerning my health. she is an excellent doctor who listens

November 17, 2019 11:00 PM

Professional clearly communicated and knowledgeable

November 17, 2019 11:00 PM

I went in for my annual visit. There is a PA in training in this office. I realize this is a learning opportunity; however, sometimes it is not comfortable for the patient to have multiple people in the room if the issue of concern is sensitive.

November 16, 2019 6:05 PM

I have phoned her office 3 times within one week and never received a call back. I wanted to know why she prescribed a medication and what my diagnosis was for putting me on this medication. I went to her for a follow-up for bronchitis.

November 15, 2019 11:00 PM

first visit. impressed with dr and office staff.

November 12, 2019 2:11 PM

She always asks if I'm feeling good. She asks if the injection I had done in the back helped. If I had any problems getting my meds on time

November 12, 2019 2:11 PM

She does a very good job of checking how was from the last visit

November 12, 2019 10:38 AM

The appointment was for a pre-op exam. I was given an appointment quickly for surgery in 3 days. The doctor treated me VERY well.

November 3, 2019 6:00 PM

Dr. Nisipeanu has to be the best Dr. ever!!! She makes you feel like you matter, takes her time and is easy to talk to.

October 28, 2019 7:00 PM

Acute rash due to alleged allergic reaction directed me to an alternate provider. MD glanced at rash and immediately diagnosed without consideration of my (patient) report. MD no longer LISTENED to the patient but focused on her assessment. MD requested patient contact her if no resolution within 5 days. Patient attempted contact after 5 days treatment via Myadvocate portal with no response. Patient followed up with MD via phone contact with NO return communication. Patient confirmed MD was in office on date(s) of attempted follow up via portal/phone contact.

October 25, 2019 7:00 PM

Dr. Nisipeanu is an excellent doctor. She makes every appointment thorough and had a very comprehensive knowledge base. Her manner is very caring.

October 13, 2019 7:00 PM

dr Onana N is wonderful my entire family see's her and we all think she is Great don't come across to many doctors that act are about your overalls well being but I must say that doctor onana does !!!

October 11, 2019 7:00 PM

I was happy that I was able to get in right away. Unlike my previous MD office which is known for " scheduling appts in 2-3 mons" not lenient nor considering that you needed a short wait time, next available appt is always 2-3 mos ahead.

September 30, 2019 7:00 PM

my experience with this provider was very good.

September 29, 2019 7:00 PM

Its unlikely I will continue to see this physician. I need a doctor whose staff will answer their phone. Your call center and central scheduling are simply a barrier to healthcare. Your system is broken. And you broke it. There must be some way to speak to my MD beside driving to her office and barging in.

September 22, 2019 7:00 PM

Had no idea I had bronchitis or pneumonia, even though I am prone to both. I appreciated that she heard the bronchitis and requested the chest xray, which showed the pneumonia.

September 21, 2019 7:00 PM


September 21, 2019 7:00 PM

would never go back to her

September 9, 2019 7:00 PM

Dr. Nisi & her staff are great people to work with and make you feel very comfortable

September 6, 2019 7:00 PM

excellent. provider

August 30, 2019 7:00 PM

My experience went well as always. Doctor always listens with direct attention, gives feed back and very patient I wouldn't change providers unless I had to...much appreciated...
