Diana Kasza, President, started in business after serving as a controller of a medium-size corporation. Prior to the controller position, she served as a staff accountant for 5 years with a public accounting firm in Big Rapids, Michigan. The inception of Simply Counted Business Services, Inc. began in 1997 as a sole proprietorship. Our original name was The Mammen Group Inc., which was incorporated in 2002. We moved to our current location in 2010, with one staff member.

In 2012, we changed our name from the Mammen Group, Inc. to Simply Counted Business Services, Inc. It better defines our environment and the passion we have for serving clients.
