Dr. Derken is the Best!!

I have been a patient of Dr Derken for many years. She is an exceptional physician and takes the time to answer all your questions and concerns. She is an asset to the Advocate Healthcare family

Everyone is very professional and nice. I feel cared for when I'm done with my visit.

I think everything went vary well. Felt comfortable with Dr Derken.

Most efficient. Service was excellent and fast. Office staff friendly.

The nurse who took my initial information in the exam room could use more training in diction. I had to ask her to repeat her questions and I am not hard of hearing. I think her speaking voice was not adequate.
