At Signature Smiles Dentistry, we believe a dental practice is only as good as the staff that works there. For this reason, we are proud to boast about having the best dental team. We also love mentioning that we offer the best dental practice for Parker, Colorado residents. Dr. Gunning DDS and our dental team are much more than a practice; we are a family. We strive to provide our patients with the best dental services that include general, cosmetic, and restorative options.

About Dr. Gunning DDS

Meet Dr. Nate Gunning! He was born and raised in Mesa, Arizona where he completed his undergraduate degree in Business Management at Arizona State University. After attending dental school at the University of Colorado, he fell in love with this beautiful state and never wants to leave! When he isn’t reading dental articles, attending continued education classes, or learning as much as he can about dentistry, you can find him hiking in the mountains or playing volleyball with friends in the city. He is excited to join the Parker community with his wife and two children and is honored to have the opportunity to give you your signature smile.
