OUR STORY | OVER 6O YEARS OF EXCELLENCE

FRED TERHAAR
Founder
TERHAAR stained glass studio was established in 1959 by architectural designer and stained glass artisan Fred Terhaar.
Fred learned his craft and love of glass while working as an apprentice on the famed glass windows of St. John’s Abbey Church in Collegeville, Minnesota, designed by Marcel Breuer.

GARY & TOM TERHAAR
Two Sons
Fred trained his sons Gary and Tom in the tradition and techniques of fine glasswork.
Today Gary and Tom continue to be recognized for their excellent reputation in offering the finest quality design and fabrication of stained-glass work. They both spend their time mentoring their passion for stained glass to two brothers who desire to build upon the 60-year legacy.
