The office staff and nurses are great. Dr. Challa is friendly and sensitive to patient issues.

July 8, 2020 10:31 AM

Dr. Challa (and his office staff) have always been very efficient in how the office is run. On this visit they (the staff) were not. I would 1 hr. past the appointment time and they thought I had not showed up even though they had checked me in on my arrival. They did apologize for their mistake.

July 8, 2020 8:19 AM

The experience was good all were very nice and they explained in my language.

June 29, 2020 2:53 PM

I think Dr. Challa is very personable and caring about myself and family. He also worked with me and other back to work Doctors for my employer to make sure I could return to work after my surgery.

I am a doctor, currently not working for health reasons. I have referred to this group for many years, and continue to do so.

Dr. Challa asked the right questions based on my health history and ordered the correct tests to ascertain my exact heart problem. The med he prescribed make sense to me and he listened to my concerns about unnecessary meds. Very good doctor.

December 21, 2019 6:08 PM

The whole office made me feel relaxed and comfortable.

December 17, 2019 10:14 AM

Provider was attentive and decisive. He explained well what he was assessing and this gave me confidence in him.

October 17, 2019 7:00 PM

This was my last visit, I'm doing well enough that I don't need to see a heart doctor anymore - I'm glad but also sad, this is a great doctor - he really seemed to care about my health, I got great care from him & his team and I'll be recommending them often.

October 7, 2019 7:00 PM

Provider is always upbeat and positive! Provider always inquires about diet and exercise! Provider always explains medications and need to continue!

June 11, 2019 7:00 PM

Very bad.

June 4, 2019 7:00 PM

Excellent care, professionally and personality.

June 2, 2019 7:00 PM

Dr. Challa is an excellent cardiologist - his office staff needs to have a better "customer relations" attitude sometimes - the nurses are great - just hard to get passed the admin. staff to get answers.

May 22, 2019 7:00 PM

He took my blood press. - listened to upper body with a stethoscope, read results of my GPS blood tests on computer, I asked about a couple meds changes GP made (he said they were good changes. When I got paper work at the end of visit it said to discontinue GAVISENESIN 400 MG. TAB that I've been taking to stop phlegm build up & intense coughing. I feel I can't go without. We never even talked about that (lung problem). We don't discuss anything much unless I ask. I wish he would volunteer and explain more. It's my body I want to be informed!! He shows little personal interest in my health communication!! He observes and makes decisions. Hey I want to be part of the process!!

May 16, 2019 7:00 PM


April 28, 2019 7:00 PM

Dr. Challa is a kind, sympathetic doctor who listens well.

April 24, 2019 7:00 PM

Bad experience.

February 17, 2019 6:00 PM

All visits are always very satisfying.

February 17, 2019 6:00 PM

Advocate Cardiology got me in as soon as possible on the coldest (-21 degrees) day of the year. Everyone was accommodating and helpful.

February 12, 2019 6:00 PM

He's new to me but I think I'll like him. Have had only 2 appointments with him. So far so good.

November 26, 2018 6:00 PM

My office visit with Dr. Challa was very positive. I found it odd that the pre visit data gathering with I believe the nurses did not already have much of my information as I am a...

November 23, 2018 6:00 PM

Very caring doctors nurses & staff.

November 2, 2018 7:00 PM

Dr Challa was very helpful. I came because my oncologist, whom I have been seeing every 3 weeks, usually finds my blood pressure on the high side. My endocrinologist recommended that I see a cardiologist. Hence this visit. Very pleased with him and his Elgin practice. Also very convenient.

October 26, 2018 7:00 PM

Very bad office staff - they need to be trained to show courtesy and respect for patients and their time. This was my second visit to this office and the 2nd time they showed no courtesy-respect for patients. Pretty terrible . the staff blaims the issue on the office manager - who wasn't even there. Dr. is good but when patients are thoroughly disrespected upon their arrival in the office - everyone's blood pressure goes up and after that even the dr. was not interested in providing due care. Overall a very bad practice here

October 22, 2018 7:00 PM

Dr. Challa listens to my concerns and cares about my health and future care.

September 30, 2018 7:00 PM

I really like this Doctor

September 24, 2018 7:00 PM

well done , maybe my meds should be reviewed

September 23, 2018 7:00 PM

Glad to see the office has been renovated. More space for patients in the waiting room.

September 17, 2018 7:00 PM

This was my first visit with this doctor & am happy to have him as my doctor!

September 2, 2018 7:00 PM

exellent experience

April 18, 2018 7:00 PM

Diagnosed bronchitis, prescribed medicine, followed instructions. Cleared up in about 3 weeks.

April 18, 2018 7:00 PM

The new facility is very nice - one problem - more signs for the entrance on Rt. 47 - a little hard to know where to enter or that it is even there! Both north & south.
