What started out as the old Willmar Post Office in 1937 has grown and expanded over the years to become the current location of the Certified Public Accounting firm known as Conway, Dueth & Schmiesing, PLLP. In 1973, Rick Conway began working for Roger Nelson. Just five years later, Conway was able to purchase Nelson’s practice and form Conway, Dueth, & Associates in 1981. That same year, the company moved into 331 Professional Plaza in Willmar. Conway, Deuth & Schmiesing, PLLP was then founded in 1985. Roger Deuth and Milan Schmiesing each share a common goal of helping their clients reach their maximum potential. The firm grew based on the highest standards and ethics of the accounting profession.
