Hi, I’m Kat! I graduated from the Dental Hygiene program at ECC in May 2025 and am passionate about providing my patients with the highest quality dental care. In June 2025, I was blessed with the opportunity to share my skills with the community in Kenya, Africa—an experience that deepened my appreciation for life and strengthened my love for my career.

Outside of the office, I love walking my dog, hiking, skiing, and spending time with family and friends.
