I am very happy and pleased with this practice, especially Dr. Koo.

Dr. Koo is incredibly kind and thorough, the amount of time that he spent with me was not only remarkable, it was so appreciated. I am thrilled to have found such a patient and knowledgeable physician!

Even though I was not feeling well (hence the reason for my visit), the reception staff, doctor and doctor's nurse made this a pleasant experience.

I feel my health issues are well cared for by Advocate.

I feel confident my health is in good hands with Dr Koo.

Dr Koo is all about the patient. He is responsive to my questions and sensitive to my concerns and has answers and recommendations that make me feel comfortable. Advocate is fortunate to have a doctor of such high caliber and we as patients benefit the most. I completely trust him and his staff with my health.

I love Dr Koo. I used to see him in a location that was very difficult for me logistically; it was difficult to get into the building because of my disability. I didn't care He's a great Doctor. Now he is in the new advocate building at 10 N Cumberland! Very easy access.

Dr Koo is the best.

Dr Koo is a caring professional great attitude always asking for any questions that I might have or concerns about my health physically or mentally hope to keep him for life my self and my wife
