Dr. Gregory J. Matke

Hi, I am Greg Matke, it is my sincere pleasure to treat you at We Smile Dental. My interest in dentistry began long ago as a small child when I would tell my mother that when I grew up I was going to be a dentist.

As I grew and learned more about being a dentist I knew that this was what I wanted to do as a profession. Since graduating from the University of Illinois at Chicago College of Dentistry in 1996, I have been in private practice in the Chicago area. From that time on I have expanded my knowledge and skills through numerous continuing education courses including but not limited to Surgery, Implants, and Orthodontics. Through these courses, I have been awarded fellowships with the International Congress of Oral Implantologists, Misch Implant Institute and am a graduate of the Chao Pinhole Surgical Technique™.

I love being a dentist and hope you will find that at We Smile Dentist If you are our patient you will feel that you are part of our family.

Outside of dentistry, I enjoy spending time with my wife and our 2 children.
