Sierk Children's Dentistry

Dr. Jon Sierk

Dr. Jon has been serving the children and families of Colorado since completing his pediatric specialty training in 2003 and is proud to be a diplomate of the American Board of Pediatric Dentistry.

"I am humbled by the trust our patient families have in the care that my team provides. When a child is in our care, they are treated as if they are one of our own.”

After growing up in Bettendorf, Iowa, Dr. Jon graduated from Northwestern University in 1996 where he divided his time between studies and the varsity soccer team. He then returned home to attend dental school and then on to complete an extensive three-year residency at the University of Iowa specializing in the dental care of children, and patients with special health care needs.

Dentistry is a family affair for Dr. Jon. His father and two brothers also proudly graduated from the University of Iowa’s College of Dentistry. Dr. Jon is on staff at the Children’s Hospital of Colorado and served as an adjunct professor in the training program there from 2005–2011. He is also certified in Advanced Cardiac Life Support (ACLS) as well as Pediatric Advanced Life Support (PALS).

Dr. Jon volunteers time and resources to support Colorado families through community outreach programs.  Dr. Jon has participated in medical mission work in many locations within the Dominican Republic, extracting teeth for underserved families in remote areas.  

In his free time, he loves to travel and hike with his fiancée Stacey, golf, read, keep up with his nieces and nephew, and cheer on the St. Louis Cardinals. Telluride, Bandon Dunes, and London are a few of his favorite places. 

Dr. Jon truly loves working with his child patients and is proud to have been named to "Denver's Top Dentists" by 5280 Magazine yearly since 2011.
