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.

Joanne Receptionist/Scheduling Coordinator Joanne
Receptionist/Scheduling Coordinator

I have been with Knowlton & Masson Dentistry since 1987. We have gone through many changes over the years, and have all grown together as a close team.

Along with my other administrative co-workers, I schedule appointments for the doctors and hygienists, complete insurance billing and inquiries, answer phone calls, and confirm appointments. I look forward to greeting every patient with a smile and answering any questions they may have about treatment needs or insurance benefits.

My husband Tom and I have lived in Sparta since 1979. We have two adult children: Jennifer who lives in Clearwater, FL, and Shawn who lives in Chicago, IL. We also have 2cats that still live at home. I enjoy knitting, gardening, reading, jewelry making and biking.

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.
