Dr. Leszek Ballarin, MD

The first doctor I met in Chicago, who devotes a lot of time to the patient, is not in a hurry, and is interested in his problem.Nurses very nice and helpful.The girl at the registration is incredibly nice and courteous.I felt very well cared.I highly recommend.I will definitely become a regular patient of this office.

Brought 94 year old uncle in and went very well, he and staff were very nice. Listened to concerns and suggestions and set up additional appt for blood work. Very pleased so far.

Great doctor . Provides enough time to explain What really bothers you . Very accommodating and with excellent bedside manners. I am his patient for about 10 years and still very satisfied. His staff is extremely friendly and helpful , helps you with appointment with other consulting doctors and scheduling appointment for your recommended tests.

1. Never on time 2. His office doesn't accept electronic payments 3. It's almost impossible to reach him by phone--even to make appointments 4. My wife has a history of lactose intolerance, but she must drink milk in front of the children at work. She asked him to write a brief letter explaining her stomach issues, but he wouldn't--he said that only a gastroenterologist can write one. 5. I went to his office twice last fall for a flu shot, but he told me both times that he ran out! Some PCP!

Not the nicest doctor or nurses in the office. Yelled at an elderly patient about her changing insurance, when in fact if they would spend 5 min of their time to double check, they would find out that her medicare insurance in fact has not changed. I guess they were more worried about getting paid, than about stressing the poor elderly client.

He comes in 5 minutes and walks out. His go to is just giving you meds no tests or anything just meds and see of they work.
