Dr. Koziol is amazing. He is very respectful, thorough with his answers and calm. Always let’s you know what the next step is in the process of the appointment . The staff is very nice as well. I went there with my daughter (4 years old ) once and they put on cartons for her and kept an eye on her in the waiting room. They even gave her some snack . They are all easy to communicate with and are always smiling and positive . I would recommend the doctor and the office in Elk Grove Village .
