staying compliant with state regulations is not optional — it is a core business obligation.
This guide covers the primary regulatory body, the governing law, and the most important
compliance considerations specific to Wisconsin.
Primary Regulatory Agency
Wisconsin Department of Safety and Professional Services (DSPS)
