Meet The Wildlife Science Center Staff


Peggy Callahan: Founder, Executive Director

A native of Rochester, MN, Peggy first became interested in canines through her family dogs who were her constant companions. Inspired by a reply to a letter she had sent to a wolf biologist asking for a job at age eight, Peggy earned a degree in Biology from Carleton College and began working for the “Wolf Project” in August 1985. For five years she managed the colony for research, focusing on refining chemical immobilization techniques for use in the field. In addition to her wolf time, Peggy also assisted with studies involving Black Bear, Red Fox, White-tailed Deer and Wolves in the field, including assisting with the Isle Royale wolf captures in 1989 and 1991. When federal funding for the Wolf Project ceased in 1991, the Wildlife Science Center was created by Peggy to keep the facility open. After three years of intensive building and program planning, the Wildlife Science Center opened it’s doors to the public as a non-profit education and research facility. Scientific Papers
