Welcome to Sergeant Bluff Smiles! 

My name is Laura Giese and I am excited to introduce you to Sergeant Bluff Smiles. I was born and raised in Sioux City, graduated from Creighton University in 2004 with a Bachelor of Science in Biology and again in 2008 with my Doctorate in Dental Surgery.  My husband, Bob, and I have three children- Cal, Hazel and William. They keep us busy and we wouldn’t have it any other way! 

I am passionate about what I do.  I sincerely care about each and every person that walks through my door.  I’m here to serve the community.  My goal is YOUR optimal oral health. A healthy smile is a happy smile.
