A native of Minnesota, Stroncek studied wildlife and fisheries biology at the University of Montana and the University of Alaska, and then completed two years of intensive art instruction at Colorado State University. His lifelong obsession with natural history and the outdoor experience has led him to portray outdoor-related subjects most frequently, but not exclusively.

A full-time artist since 1980, Stroncek's works are included in private collections throughout the U.S., including the L.L. Bean Co. of Freeport, Maine, as well as abroad. His images have appeared in such outdoor and fine arts publications as: Sports Afield, Field & Stream, Fly Fisherman, Trout, Southwest Art, Wildlife Art News, Sporting Classics, Yankee, In-Fisherman, and Gray's Sporting Journal. His works were chosen for the 1985 and 1988 California Wild Trout Stamp-print design. He was a regional winner in the1987 "Arts for the Parks" competition sponsored by the National Park Academy of the Arts and has shown in several "Birds in Art" exhibitions at the Leigh Yawkey Woodson Museum. He won "Best of Show" at the 1995 C.M. Russell Art Auction, Great Falls, Montana. His work is included in the permanent collection of the National Museum of Wildlife Art, Jackson, Wyoming, and participates regularly in the museum's annual "Western Visions" show.
