Katee Bastianello- Registered Dental Hygienist

Hi! My Name is Katee Bastianello and I am the Registered Dental Hygienist here at Wrightstown Dental. My Husband Jerod and I recently moved to the Wrightstown Area and love being part of such a welcoming community. We are the proud parents of four sweet little ones, Reed and Claire and Grace, and Ellie. We also have a loving golden retriever named Moe, who we consider our firstborn! I enjoy being with my family, spending time at my husband's family cabin in the Upper Peninsula, running, crafts and sewing. I love working in dentistry and getting to know my patients personally! It is my goal to provide a comfortable cleaning and to educate my patients on how to keep a healthy smile. I began my dental career by completing the dental assistant program at Fox Valley Technical College. Over the years I have worked in a variety of dental offices as a dental assistant, including oral surgery. I then went on to earn my Associates Degree in Dental Hygiene from Northeast Wisconsin Technical College and joined Dr. Lasslo's team in August 2012.
