Office staffs are very well trained and professional. They always welcome with professional attitude and try to help me with any questions that I have.
They have been better with waiting time compare to a year or two years ago (used to be 20-30mims waiting. But almost 5mins to no waiting time now with covid-19 rules)
Doctors are almost the best in this field in Chicago. It could cost you but you will get a result.
I do recommend to discuss your needs and wants enough before the service start and right it down.
