Independently wealthy from his decades in the wrestling business, Stecher began a wrestling office as a promoter in Minneapolis. He was taken by the city after a trip in the early 1930s and relocated his family from Nebraska to Minnesota in 1933. His first program was on February 21, 1933, with the wrestling debut of football star
Bronko Nagurski. Stecher achieved great success and became the nation's top wrestling promoter. He formed business relationships with various promoters in neighbouring states and aided an upstart
Sam Muchnick in created his territory in St. Louis, sending him wrestlers to help the outfit grow. Stecher's career in the boxing business continued alongside his wrestling tenure. He was the exclusive promoter recognised by the Minnesota Boxing Commission and was a prominent figure in the sport from 1944-1954. He put on scores of bouts with boxing stars such as
Jackie Graves,
Rocky Graziano,
Willie Pep,
Beau Jack and
Sandy Saddler. He joined Maxwell Clayton and
Pinkie George to form an innovative working arrangement to bring top-level boxing fights to the American
Heartland. Other promoters joined the successful collaboration, and soon thereafter a similar professional wrestling agreement was made. Pinkie George organised a symposium in Waterloo, Iowa with regional promoters, including Stecher, at which the
National Wrestling Alliance was formulated. ==Later life and career==
