Born in Dayton, Ohio, Buz attended the University of Pennsylvania’s WhartonSchool and Harvard Graduate BusinessSchool. A former bank executive, he owned Enterprise Investment Company and taught evenings for twenty-six years as a Professor of Management at Regis University and the International School of Management in Colorado Springs.
Very active in regional fund-raising, Rieger was founder of the Colorado Springs Pioneers Museum Foundation, a life member of the Colorado Springs Chamber of Commerce, and Chairman of the Board of Memorial Hospital, becoming the campaign fund-raising director for the new hospital building during the early 1970’s, chairman of the Board and campaign director of Memorial Hospital and Pikes Peak United Fund campaign.
Buz’s primary cultural and historical interest for over forty years has been lecturing about the historical importance and unique heritage values of Western American 1850’s to 1890’s wood-engraving art masterpieces.
Buz and his wife, Sue, founded and endowed Pet Companionship for Seniors. They are presently active with Peak Education where Buz extends his love for local history to the students and families of Peak Education through a hiking program providing opportunities to explore the richness of the mountains surrounding Colorado Springs while he shares the historical perspective of pioneers, artists, and early city events. The student's favorite hike is the "Treasure Hunt" hike where students find the gems Buz carefully hid in the early morning hours before the hike.
