Tom Mansfield, President​

Tom started his career as in the hospitality industry in Vail, CO. Later, he acquired a retail floral and gift store in the area. After selling the store and 14 years in Vail, Tom moved his family back to his hometown of St. Louis, MO. There he started a retail wine and spirits shop in Chesterfield, MO, a suburb of St. Louis, and earned his Sommelier Certification. Eventually Tom sold the business to an investor and jumped into the exciting world of credit card processing. As a business owner, Tom understands the frustrations and importance that credit card processing and all forms of transaction acceptance entail in any retail operation. His understanding of the real life processes that merchants experience drives his ability to empathize and offer practical solutions to issues vital for a merchant’s profitability and growth.

Tom's expertise in the industry spans various aspects. Tom has been designated court expert in cases involving credit card processing and is very attuned to current changes in the industry. Tom holds a Bachelor of Science Degree from The Colorado State University School of Business Administration, Magna Cum Laude.
