I am so thankful to be part of a wonderful dental team who is strongly committed to providing every person who walks through the doors an opportunity to participate in their own dental care. Every day I’m here, I get to meet warm people who have become like family and friends. As a Dental Hygienist I enjoy being able to share my enthusiasm of cleaner teeth and healthier gums. I like being able to have conversations about your daily oral routines and be able to work, adapt, and introduce information and tools to be able to help each person maximize their oral and overall health.

I hope to be able to share and exchange stories and laughs while you’re in the chair with me and make it an enjoyable experience. In my past time I enjoy fishing, cooking, and travelling. Looking forward to sharing my time with you.
