Dr. Thayu is an exceptional doctor. She takes the time to listen and cares about my health. She never seems rushed and always happy.

July 29, 2020 2:44 PM

First visit with Dr Thayu as my new doctor, positive experience

July 27, 2020 4:04 PM

She is awesome. I wouldn't go anywhere else.

July 27, 2020 4:04 PM

Excellent She directed me to the specialist that I need.

July 25, 2020 6:15 AM

This was my first visit with Dr. Thayu. She took over for Dr. X, who I had been with for 40 years! She was just excellent and an easy replacement to talk to! I also liked the nurse. She was easy to talk to as well!

July 25, 2020 6:15 AM

I love Advocate! The doctors and other associates are wonderful!

July 24, 2020 11:15 AM

Dr. Thayu is the best doctor I have ever seen. She takes time to hear you out and actually cares how you are doing. She never rushed to the next patient. I always trust and respect her medical opinion it is such a relief to have a doctor that I can fully trust has my best interest at heart.

July 22, 2020 8:52 PM

Dr. Thayu is insightful, resourceful, perceptive, empathetic, knowledgeable, and helpful. she is an amazing resource and the best PCP I have ever had.

July 22, 2020 8:52 PM

very helpful. i am trying to make necessary changes.

July 21, 2020 9:08 AM

excellent as usual

July 21, 2020 9:01 AM

Fabulous practice, love Dr. Thayu!! Professional, intelligent, so blessed to have her!

July 21, 2020 9:01 AM

Always wonderful.

July 20, 2020 5:10 PM

this was my first appointment with Dr Thayu and everything went as expected

July 20, 2020 5:10 PM

Excellent visit and happy with the referral to her

July 20, 2020 6:36 AM

I would have preferred to talk directly to the provider regarding my blood test results instead of the nurse calling me. I had a few questions that the nurses can't answer.

July 20, 2020 6:36 AM

I don't really like the online experience. Sometimes it needs to be in more layman terms. For example, I could not really understand my blood test results.

July 13, 2020 1:29 PM

I appreciate that Dr Thayu is open minded and actively listens to what I say. She realizes that what is the accepted norm might not be what is best for an individual. She has a holistic viewpoint.

July 13, 2020 3:04 AM

Although this was my first appointment with Dr. Thayu, I found her to be pleasant, thorough, and open to any questions I had.

July 7, 2020 5:13 PM

I really like Dr. Thayu. While remaining very professional she is easy to talk to and I feel she sincerely cares about my well being. She never makes me feel rushed and I know the way medical business are run now that is NOT easy to do. Keep in mind I work in the Insurance Industry.

July 6, 2020 3:04 PM

Feel very comfortable with Dr Thayu and would recommend her to anyone

July 6, 2020 3:04 PM

Great experience

July 6, 2020 1:19 PM

Excellent. We covered all the basics . This was my initial visit with this provider. My previous GP has retired. Very pleased with this new provider.

July 6, 2020 6:35 AM

Dr. Thayu always spends as much time as necessary to satisfy my medical needs, there is never a feeling of being rushed or taking too much time.

June 29, 2020 5:22 PM

Dr. Thayu is the best! we will be moving out of state and I will miss her and her compassion. Great person!

June 29, 2020 4:52 PM

On time, professional, proactive

June 29, 2020 4:52 PM

great experience...although the next day I needed to make a pre op visit for upcoming cataract surgery. the receptionist indicated I couldn't gather in until a month after my request. I told her DrThayu indicated that she would make time for me. the receptionist said she would talk with dr. and get back to me. 3 weeks later, I'm still waiting.

June 22, 2020 9:35 PM

I felt that Dr. Thayu had spent some time looking at my files prior to my visit.

June 22, 2020 4:14 PM

very pleasant answered all my questionseasy to talk to.

June 9, 2020 7:26 AM

so patient and welcoming

April 24, 2020 8:57 AM

Phone visit due COVID-19. She listened, asked questions, came to a conclusion, prescribed needed meds.

April 24, 2020 8:57 AM

Good conversation, comfortable.

April 6, 2020 7:43 PM

Dr Thayu is consistently personable, knowledgable, and professional. she is an excellent communicator and it's always a pleasure to see her and the staff.

April 4, 2020 12:08 PM

Thankyou Dr.Thayu.

April 4, 2020 9:18 AM

Dr Thayu is always very personable & professional. She listened to my issues & prescribed a medication accordingly.

April 4, 2020 1:51 AM

March 31, 2020 9:45 AM

It was a phone visit do to the Covid-19... I found this to work very well...

March 31, 2020 9:45 AM

I really respect Dr. Thayu and she has very good bedside manner.

March 21, 2020 7:07 AM

new patient for dr Thayu. she was very thorough.

March 16, 2020 5:12 PM

Dr. Thayu is an excellent physician. I saw her this time at Good Shepherd Fitness Center and that was quite enjoyable.

March 16, 2020 3:28 PM

I have had excellent experiences with my primary physician and the specialists that I have been referred to from Advocate.

March 12, 2020 9:54 AM

Dr. Thayu is great. She listens carefully, responds appropriately and prescribes necessary meds or tests.

March 10, 2020 10:54 PM

March 10, 2020 5:47 AM

This was my first appointment with Dr. Thayu and it was the best first appointment I have ever had with a doctor. The staff was wonderful too!

March 9, 2020 6:19 PM

Always a pleasure to work with Dr. Thayu

March 9, 2020 5:03 PM

I felt very good to talk about my questions and concerns. you listened and your answer helped me.

March 9, 2020 5:03 PM

very good experience.

March 9, 2020 10:16 AM

I am very pleased!

March 7, 2020 12:09 PM

I've been a patient of Dr. Thayu for a very long time. Love her. Recommended her to my parents as well as friends.

March 7, 2020 12:09 PM

Dr. Thayu knows me and my family - never fails to ask about everyone individually. I feel safe and taken care of by her and her staff.

March 7, 2020 5:35 AM


March 7, 2020 5:35 AM

trouble making an appointment.

February 29, 2020 11:08 AM

Dr Thayu is the best doctor I have ever seen...I am always confident of her knowledge and practice.

February 29, 2020 11:08 AM

Advocate is so large and has become too impersonal.

February 22, 2020 3:34 PM

I'm a new patient. This Was a 6 month follow up. Will return in another 6 months. Blood tests were good overall. So far I'm happy with this provider.

February 18, 2020 8:14 AM

I feel that Dr. Thayu is under a lot of stress. She wasn't her usual self this time. The exam felt rushed and perfunctory, which has never been the case in the past. And then I found out later (I don't always check my voice mail because most of it is junk) that the office had wanted to cancel my appointment, so now I feel bad that maybe she had to come in special? My annual physical had already been cancelled once by the office and put off a month. So I don't know what's going on. Everyone at the office seemed down and sad.

February 18, 2020 8:14 AM

It is very hard to be able to see Dr. Thayu for an illness or injury. I have had to go to urgent care throughout the year because I can't get in to see her; she is too busy. I think she needs fewer patients so that we can actually see her when we need to. What's the point of having a primary care physician if one can never get in when one is sick or injured? I have had Dr. Thayu as my doctor for over 15 years and I don't want to leave her, but I feel that she is overworked now.

February 13, 2020 11:29 AM

From the front receptionist to the prep nurse, to Dr. Thayu, I felt very comfortable with the care. As I age, it becomes so important to feel empowered about my health, and I feel the team is on my side!

February 13, 2020 11:29 AM

Love the staff, very responsive, whether returning phone calls or answering my many questions about Advantage Medicare.

February 11, 2020 9:47 PM

I really like this provider. I have been seeing her for the last few years. I feel she listens to me and does not rush me out the door

February 10, 2020 2:18 PM


February 6, 2020 12:27 PM

I was looking for a GP in the Suburbs. Dr. Thayu fits my needs.

February 6, 2020 12:27 PM

Very good experience. The office nurse was also very good.

February 4, 2020 12:36 PM

Excellent care with Dr. Thayu.

February 2, 2020 8:12 AM

Everyone at this office are great. Kind,happy,always smiling. Dr. Theyu is great. She is very caring, listens and makes suggestions.

February 1, 2020 10:32 AM

It was a quick visit to see if I had strep and the test ended up positive. It was a quick in and out appointment but I got the medicine and everything I needed to get better

January 29, 2020 8:31 AM

Love my doctor! She gives me great advice on my health.

January 27, 2020 10:23 PM

excellent bedside manner

January 26, 2020 4:39 PM


January 22, 2020 10:27 PM

Everyone was very helpful and pleasant.

January 22, 2020 10:27 PM

Lab tech who took my blood work is probably the best tech I have experienced. I don't cringe when I know she will take my blood. Hardly feel the needle plus she never misses the vein. Pleasant personality also.

January 21, 2020 7:49 AM

good experience as usual. Very easy to talk with

January 21, 2020 7:49 AM

Good experience

January 20, 2020 3:19 PM

Excellent Doctor and Staff

January 20, 2020 1:56 PM

I had the BEST nurse in the office and also in the clinic where I did a urine test. They were both absolutely delightful! They were kind and friendly, and they spent time with me. I wish i could remember their names so that someone would know what a wonderful job they did!

January 13, 2020 3:54 PM

As always, the Provider was very thorough and courteous.

January 13, 2020 3:54 PM

My visit was a most pleasant experience.

December 28, 2019 3:35 PM

She was very kind and considerate.

December 28, 2019 5:41 AM

Dr Thayu is professional and kindBest internist we have ever hadWe have referred quite a few patients to her!

December 28, 2019 5:41 AM

This was the longest I have waited in the reception areaHad to ask the receptionist how much longer the wait would be. Would have liked them to let me know prior to asking

December 21, 2019 4:25 AM

I always have a good experience with the Doctor

December 21, 2019 4:25 AM

All Positive

December 20, 2019 12:56 PM

Dr. Thayu is a great doctor, always listens and cares. Her MA was great, very friendly and compassionate.

December 16, 2019 4:55 PM

VERY difficult to get an appointment - the portal appointment system is not effective nor is the system of calling to try to get an appointment. Too many back and forth calls - appointment finally made and then cancelled. It seemed like the staff was not communicating with each other. The portal has incorrect information in it.

December 14, 2019 11:08 AM

Wonderful provider!

December 10, 2019 6:28 PM


December 10, 2019 6:28 PM

Dr Thayu always patient and eady to talk to

December 9, 2019 6:04 PM

Dr Thayu is the best PCP I have ever had.

December 9, 2019 6:04 PM

Dr. Thayu is an intelligent, sensitive, empathetic, and insightful physician, and a kind person. I trust and completely rely upon her judgment.

December 9, 2019 3:51 PM

No long wait. Friendly. Good explanation about treatment ( recommended physical therapy), prescribed 2 medications.

December 9, 2019 3:51 PM

Good experience.

December 9, 2019 1:27 PM

very nice

December 4, 2019 8:17 PM

I have seen Dr. Thayu twice and I'mvery excited to continue to see her. Very grateful for kind and good doctors.

December 4, 2019 8:17 PM

I've called the office maybe 4 times so far. Twice I've been put on hold for 10-11 minutes, nobody returns and I get kicked back into the que to start over.

November 30, 2019 6:54 PM

My visit was pleasant. Dr. Thayu is very polite and answered my questions.
