Mills started Operation Welcome Home in 2007 to honor soldiers as they return from Iraq or Afghanistan. A military mother herself, she has raised more than $200,000 to hold welcome-home parties for nearly 500 veterans and National Guardsmen and provides baskets of gift cards for food, gas, and shopping. She often provides additional services to help the soldiers. For example, she recently helped rehab a home for a veteran who was living in an unfinished structure. She also organizes trips for Honor Flight so that area World War II veterans can visit the memorial in Washington, D.C.
