Balocki is a good guy and I'm sure a good doctor.

July 21, 2020 7:45 AM

This is my favorite doctor. He never rushes me out. Always addresses any concerns I have .

July 6, 2020 2:47 PM


July 6, 2020 2:15 PM

He was very polite and professional. I felt very comfortable with him.

July 6, 2020 2:15 PM

I am a survivor of Multiple Myeloma, and my oncologist asked me to re-take all the childhood vaccines. My regular doctor could not do that. However, Dr Balocki was able and willing to do that. He is a great doctor!

June 16, 2020 10:25 AM

Fantastic bedside manner, Dr. Balocki listens to what I am in the office for, and works with me to find a plan to best suit my needs. Very knowledgeable, very polite, very helpful.

May 12, 2020 4:34 PM

Mine waas the initial visit with Dr. Balocki's Office... my prfevious retired a couple of months ago. I had been with him for more than 25 years. [Excellent]. Dr. X recommend Dr. Balocki as my new GP. I was scheduled easily and promptly... for a virtual appointment. Dr. B's staff-- is kind, patient and thoughtful. Dr. Balocki is very prepared, very interesetd in my health condition. Very understanding and thoughtful. We agreed to make some changes in medication. He suggested a consultation with a specialist--who was also extremely caring and knowledgable. I will see Dr. Balocki in another few months... and look forward to that next visit. He is a great asset to Advocate. Thank you!!!

May 12, 2020 4:34 PM


April 30, 2020 10:08 AM

Due to Covid-19 it was a virtual office visit. All things considered it was easy and went well.

April 23, 2020 8:25 AM

This was a telephone visit in regards to COVID concerns & at the time being sick. I was so impressed and extremely grateful for the length of the call, education, concern for my health, and much appreciated personal talk. Dr. Balocki has been my PCP for 5 years and I could never transfer care; I would be lost. Thank you Advocate for allowing such an amazing doctor in my life.

April 10, 2020 12:00 AM

Always a pleasure. My family has been seeing Dr. Balocki for decades.

April 10, 2020 12:00 AM

Very good as usual.

April 1, 2020 4:26 PM

Dr. Balocki has helped me turn around serious health concerns that were made known to me in November 2019. With his help and guidance I have managed to turn blood sugar and blood pressure issues from life threatening to normal levels.

April 1, 2020 4:26 PM

I have appreciated Dr. Balocki's thoughtful and patient approach with me as a new health care provider. He has taken the time to get to know me, listen to my concerns and offer honest assessments and a plan of action to help me overcome serious health concerns.

March 23, 2020 2:25 PM

love love love love the provider and his whole healthcare team they are the best

March 20, 2020 6:15 AM

Dr. Balocki was very personable and jovial. I am a technical person with knowledge of medical issues and he DID NOT dumb-down our discussions or answers to my questions - and I APPRECIATE his recognizing this without my asking for technical answers which he gave me.

March 16, 2020 10:18 PM

I needed a new Primary Care Physician and very happy with Dr. Balocki.

March 9, 2020 3:12 PM

My experience with the reception staff, nurse, and doctor were all very nice. This being the first visit, I actually enjoyed getting acquainted with my new medical team.

March 9, 2020 3:12 PM

The reception staff was helpful for getting me signed in and filling out the visitation form. A friendly nurse took my temp and blood pressure. Then the doctor arrived for final testing and many questions about how i viewed my health and what he recommended to make it better for the future. On the way out, the reception staff answered my final question and printed out my after visit summary. I exited the building feeling very comfortable with my new doctor and his team.

February 25, 2020 4:09 AM

Dr Balocki always listens and has been a great doctor. very open and takes the time with you

February 25, 2020 4:09 AM

not being able to call his office directly is a pain

February 22, 2020 9:19 AM

Visit went well, very professional.

February 22, 2020 9:19 AM

It was a good experience for the need.

February 21, 2020 5:56 AM

Went to my physical and had to wait one hour before getting in. Nurse was good. The doctor checked me out and I explained a few concerns I have about my health. He ordered a tetanus shot. Waited another 15 min. because he forgot to tell the nurse to give it to me.

February 21, 2020 5:56 AM

After leaving the exam room and closing the sliding door I overheard Dr. Balocki mocking me saying "Oh, my elbow hurts, oh, my shoulder hurts... etc." He is very unprofessional and I will never see him again.

February 19, 2020 6:09 AM

I really like Dr. J. Balocki. I don't like when I go to the dr. once a year though, I feel like I am being interrogated... My life... I take responsibility.

February 17, 2020 3:14 PM

Wait time is completely UNACCEPTABLE. I waited more than an hour past the appointment time to see the dr. It was so long, the reception staff even noticed. The wait time for this dr is ALWAYS a minimum of 30-40 minutes past appointment time, but it's usually more than an hour. This needs to change!!!

February 10, 2020 3:26 PM

He's like an old fashion doctor who takes the time to talk to you and doesn't rush you at all.

February 10, 2020 2:22 PM

Dr. Balocki always takes the time needed to go through all our health concerns. He listens well and provides great information and support.

February 4, 2020 10:02 AM

he is a very caring provider who I enjoy visiting

February 3, 2020 1:44 PM

Very thorough asked me many questions about my health and concerns!

February 3, 2020 1:44 PM

Good experience

February 3, 2020 1:29 PM

good doctor. i feel comfortable with him.

January 29, 2020 9:52 AM

Excellent, I have a consistent experience with Dr. Balocki which is very professional, information, enjoyable and relaxing.

January 27, 2020 9:47 PM

great doctor!

January 27, 2020 3:12 PM

Dr Balocki is always professional and cares about his patients

January 27, 2020 3:12 PM

Dr Balocki was concerned about my health and called me at home at 9pm the day before my appointment.

January 20, 2020 7:51 AM

My self & family have been seems him for years., unfortunately he is a dying practice today & doctors are told to but she's in & out as fast as they can: It's all about money not true care. & than is for all doctors specialists, dentist, eye doctors etc. & if you are Medicare in takes longer to get an appointment.

January 18, 2020 6:20 PM

very understanding and down to earth

January 6, 2020 8:48 PM

Dr. John B. covers all the bases in a friendly and professional way. No question is dismissed. Encourages in a winsome manner.

January 6, 2020 8:48 PM


January 6, 2020 6:59 PM

Every question answered and every concern addressed, as always. I can talk to him about anything and I am so glad to have an amazing doctor as my primary care physician.

January 6, 2020 3:02 PM

The new phone system stinks. I have a hard time calling to make an appointment.

January 6, 2020 1:49 PM

Have gone to Dr. Balocki for 25+ years. Respect him, trust him.

December 30, 2019 4:21 PM

As always, provider did excellent job. Knew my history. Had my records there. listened to all my questions and concerns. I listened to provider's comments. A positive experience.

December 30, 2019 4:21 PM

A positive experience. Exceeded my expectations.

December 30, 2019 1:33 PM

Dr. John Balocki is one of the most caring and sincere medical personnel I have ever known. The Wife and I have had John as our physician for 20 years. He is a credit to his profession. To be quite direct, many in the medical arts, I have found to be quite arrogant and condescending. Dr.Balocki and the people he surrounds himself with for staff, are the opposite of most medical people I have dealt with. Over the decades, every visit to see Dr. Balocki, a normal check up or a painful needed appointment, has been a helpful experience for Our Family.

December 21, 2019 2:55 PM

Dr. Balocki always takes his time with his patients. He answers ALL questions and explains everthing in detail. He makes my visits with him very helpful and calming. That is why I don't mind the wait for him, as I know he gives everyone the same compassion. He is the BEST!!!

December 17, 2019 10:12 AM

I love my dr., but the office doesn't seem to keep my medical records very well. Seems every year the same Q's are asked about my medical past.

December 9, 2019 5:10 PM

Very good bedside manner

December 9, 2019 5:10 PM

Very good experience

December 9, 2019 1:32 PM

I always feel safe and comfortable with any questions I have

December 9, 2019 1:32 PM

great to know there are people who care about my overall health thanks advocate

December 7, 2019 6:32 AM

Got into the exam room within 15 minutes, but sat for an hour in exam room!

December 7, 2019 6:32 AM


December 2, 2019 9:42 PM

exellent care, never rushed

December 2, 2019 9:42 PM

Dr is very personable and takes time to listen

December 2, 2019 1:23 PM

waited for 2 hours after my appointment was scheduled in the waiting room before I saw my dr. this is the second time this has happened.

November 17, 2019 11:00 PM

Dr Balocki has been my primary care physician for a decade. He has always been wonderful. Dr Warren has always been wonderful for my OBGYN needs. She is great at what she does and I am sad she's retiring.

November 17, 2019 11:00 PM

Great experience

November 12, 2019 5:48 AM

First time meeting Dr. Balocki - nice man.

November 11, 2019 9:43 PM

Waited over an hour past my appointment time, no explanation nor updates given. Didn't get bloodwork ordered because the lb was too crowded and my appointment was so delayed due to doctor being so late.

October 30, 2019 7:00 PM


October 27, 2019 7:00 PM

Dr. Balocki has been my family physician for over 20 years. I recommend him to everyone I know.

October 4, 2019 7:00 PM

good visit

September 30, 2019 7:00 PM

This provider is great, but the wait times are bad. Not sure who is at fault. Maybe the time between appointments needs to be longer for a better cushion.

September 21, 2019 7:00 PM

Dr Balocki is great - but who ever calls you back to give you results or answers a question is rude and very unprofessional. She doesn't look at test results as she tries to explain them to a patient.

September 15, 2019 7:00 PM

Dr Balocki always make me feel he cares about me and my family members whom he also sees. That is what Family Medicine should be

September 11, 2019 7:00 PM

I would recommend the dr. However, it usually takes an hour & a half to get done. I waited over an hour to see the dr. and I was asked to come in 15 minutes early.

September 11, 2019 7:00 PM

Very happy with visit!

September 9, 2019 7:00 PM

my provider was kind but was not very communicative. He was very quiet and didn't ask many questions. He didn't offer many directions even though he was providing me with 2 referrals.

September 9, 2019 7:00 PM

Good Doctor ,I am happy with his care.

September 1, 2019 7:00 PM

it was what I expected and I was treated well.

September 1, 2019 7:00 PM

Very good

August 30, 2019 7:00 PM

Dr. Balocki has treated my husband for many years and as always this visit he was very professional, thorough, and patient as he has seen my husband through a a transition time of dementia and physical limitations.

August 19, 2019 7:00 PM

First time visit. Very thorough.

August 18, 2019 7:00 PM

This was my first visit to see Dr. Bilocki and he was great for my needs.

August 18, 2019 7:00 PM

My providers are doing a great job.Dr.Balocki and Dr. X

August 3, 2019 7:00 PM

always excellent

July 23, 2019 7:00 PM


July 15, 2019 7:00 PM

Fine visit with doctor. Prescribed a test and specialist.

July 15, 2019 7:00 PM

love that guy

July 15, 2019 7:00 PM

My appointment was at 3:40 and I did not see the doctor until past 5. The nurse said nothing about running so late and I was just stuck in the room. I understand the doctor can run late and once he saw me, he did not seem rushed to get through me. It just would have been nice for more communication or a phone call before I arrived to have me come in an hour later.

July 14, 2019 7:00 PM

Balocki is thorough and pleasant to talk with. The wait time in the waiting room and in the exam room was very long.1/2 hour in the waiting room and 1/2 hour in the exam room.

July 14, 2019 7:00 PM

Dr Balocki and his staff are awesome! they helped me with my medical issue in a timely manner. Because of this I was feeling better in a couple of days instead of weeks waiting for an appointment. Dr Balocki got me in the next day making room for meso I could be treated right away

July 13, 2019 7:00 PM

helpful, informative

July 7, 2019 7:00 PM

A visit with Dr. Balocki is always pleasant. He listens, is understanding and always respectful.

June 24, 2019 7:00 PM

very good Physician

June 10, 2019 7:00 PM

We Love Doctor Balocki , he's a very Good Doctor

June 4, 2019 7:00 PM


May 14, 2019 7:00 PM

I'm extremely satisfied with Dr. Balocki.

May 12, 2019 7:00 PM

Very good doctor- the staff never calls with results from test done (last three times ).

May 5, 2019 7:00 PM

Balocki knows his medicine; knows and understands people; has outstanding skills to share knowledge and interact with people.

April 28, 2019 7:00 PM

Stopped quickly to provide new insurance card, asked for a referral and was seen by my doctor instead without an appointment. He was able to correct my problem and eliminated the need to see a specialist. Front desk, nurses and doctor were all great and helpful.

April 28, 2019 7:00 PM

the only problem is wait times in exam room can be 45 minutes to an hour

April 21, 2019 7:00 PM

I had to call to get an explanation of my blood results. pretty sure no one would have called me otherwise.

March 18, 2019 7:00 PM

Good, will follow up as advised.

March 17, 2019 7:00 PM

always a pleasure and takes the time to see how you are doing

February 24, 2019 6:00 PM

Still need to work on wait-times.

February 19, 2019 6:00 PM

As usual, treated with respect, concern and very thorough.
