As the Founder of Interstate Solutions, Frank has over 40 years of operations and customer service experience in the janitorial supply/maintenance and custodial service industry, In 1979, Frank began Interstate Supply and Interstate Services, which offered contract cleaning services to organizations across South Carolina.  Over the next three years, the companies grew to serve twelve major accounts, employing over one hundred employees.  In the early 1980s, Frank decided to sell Interstate Services, so he and his team could dedicate their time to becoming the premiere janitorial supply and equipment maintenance company in the Carolinas.

During the next 10 years, Frank continued to grow Interstate Supply, adding additional services that were of value to their growing list of textiles, manufacturing, and utility clients in the region.  Customers included: Bowater (Resolute), Duke Energy and Springs Industries, Hoechst Celanese, and other Fortune 500 companies and major utilities.  We continue to serve many of these companies today.

Over the years, Frank has had the opportunity to work and train under several notable experts in the cleaning industry.  Some of those include Dr. Michael Berry (EPA research Professor at UNC and Director at the Simon Institute, which is a non-profit group dedicated to professionalizing the cleaning industry), Don Aselett,  America’s “King of Clean” (, and John Walker, President of ManageMen, Inc., ( and the founder of Janitor University.

For over 40 years, Frank has taught thousands of individuals a comprehensive approach to total custodial cleaning and training.  With training programs ranging from basic restroom cleaning, total and floor maintenance to equipment use and maintenance, Frank and Interstate programs set a standard for professionalism in the cleaning industry.
