Meet The Team

We love Dr. Sierk and his staff. From the minute you walk through the door to the minute you leave you are treated with such great care. My boys have never complained and actually have a great time when we go. We had a small incident with an injury to my son's mouth and they were able to see us right away, and took such great care of us. We highly, highly recommend Dr. Sierk and his staff.

We Are Here for You

Dr. Sierk is very proud of his team, and most importantly the personal care his team provides to the families in his practice. We strive to create a family-oriented, caring atmosphere. Our talented team members are experienced working with the number of dental benefit and insurance plans that are represented in our area. We also understand that dental care for kids can produce some anxiety and do everything we can to make our patients comfortable. Dr. Sierk wants every patient and family in our office to be treated as he would want his own friends and family treated. We understand that families are very busy and we do our very best to accommodate appointments to fit your needs and can schedule multiple siblings at once if needed. At Sierk Children’s Dentistry we want our families to feel at home, we are here for you.

Ashley’s years of experience as the mother of two beautiful children and as a dental assistant help our patients overcome their anxieties and feel more relaxed in our office.
