LuAnn Financial Coordinator LuAnn
Financial Coordinator

I joined this practice in 1994 as a receptionist and have recently changed positions to financial coordinator. As a “numbers” person, I love my new position. I enjoy helping our patients with their financial needs. I will do my best to help you make your treatment financially possible. Dealing with insurance companies can be very trying, but I get excited when I can help a patient completely understand their benefits, and resolve problems.

I have been married over 28 years to my awesome husband, John. We have three beautiful daughters and a wonderful son-in-law: Trisha & Jason, Candi and Kelee. I teach piano, and enjoy reading, scrap booking and family time on my days off.

Mary Jo Scheduling Coordinator Mary Jo
Scheduling Coordinator

I have been with Knowlton & Masson Dentistry since 1993. I started as the Sterilization Technician, and shortly thereafter began my role as the Scheduling Coordinator.

My administrative duties include confirming appointments, answering incoming calls, and sending periodic mailings, which include postcards for upcoming hygiene appointments. I have enjoyed the challenge of new technology. It is my goal to make you feel comfortable by adding a personal touch to your visit.

My husband Lawrence and I live in Grand Rapids. We have an adult daughter, Monica. I enjoy reading, cooking, scrap booking, and boating.
