John Hamm designs and builds leaded-glass windows and lighting on commission in his Whittier, California, studio and began his career in glass in 1979. Trained as an artist from birth by his artist-painter father, John is a natural who has worked in many media. He found his passion when hired by a museum-quality Tiffany reproduction studio at the age of 21. He has worked full time as a glass artist since 1984, and he has run his own studio, Hamm Glass Studios, since 1989. Through the years, John has trained a number of apprentices in his studio. His passion and skills have allowed him to become one of the foremost authorities on leaded glass in the Arts & Crafts style. His commissions have included clients from all over the United States.
