Dr. Colin Kelliher grew up in La Grange, Illinois and attended Fenwick High School in Oak Park. He then graduated from Boston College in Chestnut Hill, Massachusetts with a bachelor’s degree in finance and marketing. Dr. Kelliher moved back to Chicago after college and worked as a financial analyst for two years before deciding to switch careers and apply to dental school. He moved to Alton, Illinois to attend Southern Illinois University where he graduated in 2021 with a Doctor of Medicine in Dentistry.

While working as a consultant, Dr. Kelliher enjoyed working directly with clients and fostering those relationships to help them achieve their goals. In dentistry, he has found the same passion and joy in getting to know his patients and working closely with them to achieve their oral health goals.

Outside of work, Dr. Kelliher enjoys spending time with his friends, his family, and his dog. He also loves doing outdoor activities such as hiking and fishing as well as supporting his favorite teams: the Cubs, the Bears, the Bulls and Liverpool FC.
