Dr. Kelly O’Connor, DDS

Dr. O’Connor has established himself as part of a Bourbonnais tradition of dental comfort and care by focusing on bringing his patients only the best that dentistry has to offer. Starting with his father, Dr. Leo O’Connor, to himself, and now joined by his son Derek, the O’Connors have been providing dentistry to the Kankakee-Bourbonnais area since 1953. Dr. O’Connor, a graduate of Loyola University for both undergrad and their Dental School, believes it is important to keep himself and his staff up-to-date on the newest dental advances and techniques in order to offer you and your family the most state-of-the-art, comfortable and personalized dental care possible.

To stay informed of the most current dental practices, Dr. O’Connor is a member of several dental organizations, such as the American Dental Association, Illinois State Dental Society, and the Kankakee District Dental Society, of which he was the president two times.

Dr. O’Connor’s top priorities are patient satisfaction and comfort; he has spent his career working and training to build a practice that meets and exceeds your expectations of trusted, first-rate dentistry. He looks forward to your visit to his office and to showing you the positive effects quality dental care can have on your life.


Dr. Derek O’Connor, DDS

Hello, my name is Dr. Derek O’Connor, and I am excited to share that I will be joining the team at Main Street Dentistry.  I was born and raised in the Kankakee area and am excited to return and join my father Dr. Kelly O’Connor in the practice that my grandfather Dr. Leo O’Connor started in this community. I attended Bishop McNamara Catholic High School in Kankakee before attending Butler University in Indianapolis, Indiana for my undergrad education. At Butler I played wide receiver for the football team and double majored in biology and chemistry. After graduating from Butler, I worked for CSL Behring in Bradley, & Abbott Labs in Lake Bluff before attending Creighton University in Omaha, Nebraska for dental school.

While at Creighton I received an incredible dental education with a wide variety of clinical experience not offered by many other dental schools in the country. I was able to see the impact dentistry has on the community through Creighton’s healthy smiles program providing dental screenings and sealants to elementary school students, as well as rotations at Douglas County Health Center and Charles Drew to provide for underserved communities. I graduated magna cum laude in May 2021 and was also inducted into Alpha Sigma Nu, the honor society of Jesuit colleges and universities, as well as Omicron Kappa Upsilon, a national dental honors society.

I am excited to join my father and continue the tradition of excellent patient care and service that my grandfather started, and to expand our practice in any way possible.
