Our Team
Experienced Doctors, Comprehensive Care
Both of our lead doctors graduated from Loyola University School of Dentistry and bring decades of hands-on experience in family dentistry, cosmetic dentistry, implants, and full-mouth reconstruction.
Here, you're not a number — you're part of the family. Our doctors take the time to listen, answer every question, and recommend what's genuinely best for your situation, not what's easiest or most profitable. That personal attention is why many of our patients have been with us for three, four, and even five generations.

Reviews
What Our Patients Say
Dr. Kontos is an excellent dentist. He is kind and makes me feel welcomed every time I come. The office is clean and up to date with equipment. The whole staff is awesome. I was recommended this office 5 years ago and have no regrets. I've tried other dentists in my area, but none compare to the service I receive from Millennium Park Smiles. Also the hygienist, Diana, is top notch. Thorough and gentle. If you are looking for a dental office, stop, this is the one.
Since moving to Chicago, I needed to find a new dentist. It wasn't easy after seeing the same dentist in Florida for over 20 years. The entire staff was friendly, welcoming, and made everything feel easy. A special shoutout to Cindy, my hygienist. She was fantastic and genuinely made me feel comfortable. Dr. Baboulas was great as well. Thorough, professional, and easy to talk to. No one tried to sell me anything I didn't need. I'm really happy to have found my new dental home in Chicago.
Dr. Kontos is excellent. Friendly, professional and a good listener. He presents treatment options and discusses them in language a lay person can understand. The office is clean and modern with all of the latest equipment and treatment. The hygienist staff is also excellent and thorough. A great place for Loop residents and office workers as well.
