“My child patients amaze and inspire me and in turn I strive to serve them with tireless enthusiasm and positivity. I love enjoying each and every day because each day is a gift. It is an honor that parents entrust me with their children’s care. I try to make a personal connection with every child, every time.”

Dr. Jon and his staff are knowledgeable, friendly, professional, and provide outstanding dental care for our two children, now ages 11 and 9. The staff consistently provides comprehensive treatments for prevention and dental needs on an individual basis, no matter the age. They speak to our children in terms they understand, and the staff’s friendly and kind demeanor motivate our children to take charge of their own dental health and care.  As parents, we strive to provide the best for our children, and with Sierk Pediatric Dentistry, we continue to receive the best, each and every dental visit. Thank you Dr. Jon and staff.

Simply put, Dr. Sierk and his staff are wonderful. My son has been going to Dr. Sierk for a long time and he has always received the best of care, and not just dental care, but care as a person. My son has learning disabilities and high-level autism, and Dr. Sierk and staff have always been the friendliest and most understanding dental professionals. We could never find the right dentist for our son and when we found Dr. Jon Sierk and his staff it was another great step forward in finding the type of excellent dental care he needs. Thank you Dr. Sierk, Ann, and all the dental technicians.
