Dr. Reilly attained his Doctor of Dental Surgery from the University of Illinois College of Dentistry, and his Bachelor of Science from Loyola University of Chicago. He has spent 37 years as a Dentist, and started his own practice 24 years ago.

He truly enjoys helping his patients have a healthy mouth and a beautiful smile. Most days he sees patients that he has known for many years, and takes pride knowing that he can help them keep their teeth their entire life.

Dr. Reilly provides the highest quality of dental care so our patients can attain Optimal Oral Health based on their individual needs. He wants to help his patients keep their teeth for a lifetime in Comfort, Function and Esthetics.

He has been married to his wife Diane for 38 years, who also helps out in his office. They have three wonderful children. Erin is the oldest and she is an Otolaryngologist. Michael is their middle child and he works as a pricing analyst. Mary is the youngest and she just achieved her Doctorate in Pharmacy. He is so very proud of each of his children.

He is a past president of the Frankfort Park District, Frankfort Lions Club, and Frankfort Girls Softball. He’s also a current member of the DuPage Dental Study Club and the Spear Study Club. In his free time, he tries to golf, travels, and spends time with his family.
