While the early days were focused on tax services, today we offer a full range of services including:

Firm growth has necessitated moves from our original St. Cloud Third Street location, to the 28th Ave location in 1987, and finally to our new building at 630 Roosevelt Road in 2008. In addition, through growth and mergers, we now serve clients from offices located in Albany, Little Falls, Maple Lake, and Monticello. Consequently, Schlenner Wenner & Co. has grown to be one of the largest firms in outstate Minnesota and is constantly ranked in the Top 25 CPA Firms in Minnesota as determined by the Twin Cities Business Magazine.

Schlenner Wenner History

This continuing growth and success has been made possible through the blessing of wonderful clients, many of whom have been with us for all or most of our 50 year journey. We hope to continue to serve both old and new clients by following our mission statement:

“The mission of Schlenner Wenner & Co. is to assist our clients in attaining their business and financial goals by providing exceptional service and expertise in tax, accounting, auditing and consulting.”

Since 2003, our mission and our unique ability to serve our clients have been enhanced through our participation in RSM US Alliance. Through this alliance we maintain our independence and decision making while we are provided with access to all the resources of the fifth largest accounting firm in the world.

Of course, our greatest resource is our staff. We are fortunate to have a very dedicated and hardworking staff, many of whom have been with us for over twenty years. We could not be where we are today without them.

Finally, it continues to be our great fortune and privilege to live, work, and play in Central Minnesota. We celebrated our 50th anniversary in business in 2014, we successfully raised and donated $50,000 to charities throughout the communities we serve!

Thank you for your business and support and we look forward to our next fifty years serving you.
