Dr. David M. Guerrero

Founder and Owner

Dr. David M. Guerrero was born and raised in Wichita, Kansas. Dr. Guerrero graduated from Creighton University School of Dentistry in Omaha, Nebraska in 2007 and received his undergraduate degree in Chemistry from Wichita State University in 2003. He attended Bishop Carroll High School and was a 1999 graduate.

During high school, Dr. Guerrero became interested with the dental field. On a trip to Central America, he noticed how bad the teeth of some of the children were and that is when he made a decision to become a dentist. Dr. Guerrero has a passion for dentistry and compassion for his patients. He strives to do the best for each of his patients and to formulate the best treatment plan that will work best for the situation they are in whether it is clinical or financial.

During his third year of dental school, Dr. Guerrero went on a two month mission trip in the Dominican Republic. During his time there, Dr. Guerrero provided free dental care while he lived in a mountain town with a local family. It is his dream to return to the village and begin his own mission trip group.

Dr. Guerrero would also love to start a low cost program here in Wichita to help families without insurance. Dr. Guerrero continually strives to make all dental treatments (including family and cosmetic dentistry) accessible and affordable to all his patients. He enjoys being a dentist because he gets to build a relationship with his patients and also offer them a better life style with healthy teeth. Informing patients about the latest advancements in personal dental care is very important to him. Dr. Guerrero continually strives to become a prominent name in Wichita for cosmetic, restorative, preventative, emergency, and family dentistry.

Dr. Guerrero loves playing and watching sports, especially soccer and football. He enjoys time with his family, traveling and good food. If you ever have a problem/issue Dr. Guerrero is always willing to figure out the best solution.
