Hi, my name is Cheryl, I have over 20 years of hands on experience in all aspects of Dentisty, ranging from dental assisting to management, and I am the first person you’ll see when you walk through our doors. I have been with Dr Kooyman at Signature Dental since he opened his practice February of 2007, he is a great, talented, and gentle dentist.

Meeting new smiles and seeing how helpful we can be to change those smiles is very rewarding to me. In my spare time my husband Steve and I enjoy traveling and one of my passions in cooking. I have two adult children and one grandson here in the Meridian area.
