Mindy Muñoz has served as the Program Director for the Ronald McDonald Care Mobile, fondly known as the “Tooth Truck”, since 2007. She is responsible for the overall operations and day-to-day relationships for our mobile dental clinic.

Mindy’s personal mission is to continue in a career that has the potential to impact thousands of lives. She previously spent five years administering all aspects of a medical facility caring for roughly 10,000 patient-visits a year in Rio Bravo, Mexico through the “Hands Together Ministry”, the Methodist Church’s largest foreign mission site serving Mexican people through onsite facilities, rural communities, local health facilities and in-home care. She led over 40 missions each year involving more than 1,500 volunteers. One of the administrators Mindy worked with refers to her as the “Pied Piper of Rio Bravo”.

In 2000, Mindy graduated Magna Cum Laude from William Jewel College with a Bachelor of Arts in Business Administration and attended the Oxford University Overseas Study Course in 1999-2000. She has received numerous awards for her work in the community including honors from the Red Cross, the DIF government agency and being chosen as one of five awarded for the International Day of the Woman in recognition of exceptional work performed throughout the municipality in 2003.

She was appointed to and served for four years on the Greene County Health Commissions’s Dental Advisory Board; she was the two-time recipient of the UMKC School of Dentistry’s Alumni Scholarship; and she completed the UMKC School of Dentistry Senior Departmental Advanced Studies Program with honors in Restorative Dentistry.
