Cindy Pfeiffer R.D.H., B.A.

I began my career in dentistry over 20 years ago while in high school and knew that my life’s work was going to be devoted to helping others. My educational journey began at Ohio State University, Rhodes Community College where I studied Applied Science. I also attended Northeastern Illinois University where I studied Human Resources and Adult Education. As Registered Dental Hygienists, the hygiene staff here at Colonial Dental Group is devoted to continuing education so that we are able to provide the best possible care for all of our patients. We care about the “whole” patient.

Traveling, cooking and baking are just a few of my hobbies.

I graduated from Marquette University in 1997 with a B.S. in Dental Hygiene and a minor in Human Health Science. I was honored to join the team at Colonial Dental Group later that year. The warm and friendly staff as well as the commitment to continuing education and excellence in dentistry makes working in this practice a truly rewarding experience. Outside of the office, I love spending time with my husband, 2 daughters and 2 dogs. I also enjoy gardening, music and travel.


Cathy Cannon, R.D.H.

My father convinced the dentist that rented office space in a building he owned that his 16 year old daughter needed a job and would he be willing to help out after school and on Saturday’s. I started out working the front desk and then on to assisting. The rest is history. I feel extremely fortunate to have joined the Colonial Dental Group team after working for a Periodontist who has recently retired. Since caring for many CDG patients while there, I had always admired the impeccable care that was given to their patients as well as the quality of the dentistry. I am also a part-time Dental Hygiene Clinical Instructor and Adjunct Faculty at the College of Lake County.

I enjoy working on home projects, gardening and spending time with family and friends.

Coming Soon..





I have recently re-joined Colonial Dental Group and am thrilled to see that the group is as strong and vibrant as ever! I love working in an environment that fosters growth both personally and professionally. My dogs, fishing and camping are three things I enjoy.




I have been in dentistry my entire adult life and have enjoyed every minute of it. I particularly enjoy Colonial Dental because the team is top-notch from front to back and the patients really value what we do here. In my free time, I enjoy traveling with my children and enjoy being in the outdoors.

After graduating with a business degree from North Dakota State University where I played basketball, I found dentistry through a family member and have thoroughly enjoyed my 10 plus years at Colonial Dental Group.

Being an advocate of preventative health care and believing in the power of nutrition and fitness aligns naturally with my career choice in dentistry. I became part of the team in 1998 with a degree in Industrial/Organizational Psychology from Old Dominion University in Norfolk, Virginia.

Service has always been a part of my personal and professional life and Colonial Dental Group has allowed me to pursue that as an extension of my job. I have a degree in Business Communications from Loyola University and was a dental assistant as well.
