Dr. O'Neill is one of the nicest dentists I have ever been to. Unlike other dentists who tend to treat you more like an item then a person, he takes the time to talk to you and makes you feel at ease when you come for an appointment. I happen to be very nervous with dentists in general and am happy to say that I am no longer that way! The receptionists are very friendly and helpful. The prices are very reasonable and the quality of the work I've had done is excellent. Plus, he is open on Saturdays too which works great for people who are on the go all week or happen to have a weekend dental emergency.
Pros: Easily accessible by CTA. Credit cards & checks accepted. Ample street parking. Great hours for appointments.
