For most of 2001, Detzner's Corporate Sacrilege series of paintings received a lot of attention from national and international media. As part of an exhibit at the Chicago Athenaeum Museum, The Last Pancake Breakfast sparked much controversy. The museum received hundreds of angry phone calls, as well as a petition started by a local church, asking that the painting be removed. The Corporate Sacrilege series which includes The Last Pancake Breakfast, was covered by news sources around the globe including CNN, the BBC, Newsweek, The Associated Press, and Reuters. His work was discussed on radio stations and websites across the country, and he personally received hundreds of e-mails from around the world.

He also has artwork featured in the history book, Advertising Today (Phaidon Press) in a section on resistance to advertising. Detzner is one of 70 featured artists in the full-color book, Art Scene Chicago 2000 (Crow Woods Press).

His work has been accepted in shows juried by noted artist Marisol; M. Stephen Doherty, editor-in-chief of American Artist Magazine; and David Frankel, editor and reviewer for Artforum Magazine. In 1998 Detzner received an award from Art Calendar Magazine. He also received a CAAP grant from the City of Chicago Department of Cultural Affairs in 1998. Detzner was awarded a grant for a 4-week long painting residency at the Vermont Studio Center in 1997. That same year he received the Traveling Show Award, the Crescent Cardboard Award, and Napa Valley Award from the Kentucky Watercolor Society Aqueous 1997.

Detzner received a Bachelor of Fine Arts from the University of Notre Dame. He has also taken courses at the American Academy of Art in Chicago.
