Dr. Molly Hayes, DDS

Dr. Molly Hayes is a native of the Midwest and was born and raised in Nebraska’s capitol city of Lincoln. Prior to attending dental school, she attended Creighton University in Omaha, Nebraska, where she earned a Bachelors degree in Psychology with an emphasis in health science.

Upon graduation, Molly stayed in Omaha to continue on at Creighton University School of Dentistry. Outside of dental school, she developed a passion for teaching and began tutoring junior high and high school students who desired extra help in math and science.

In her final year of school, Molly was given the opportunity to do an externship in a public health clinic that serves Omaha’s under served population.

Molly is a resident of the Chicagoland area and could not be happier to call this wonderful city home to her, her husband, and her daughter.
