John Hamm designs and builds leaded glass windows and lighting for 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 medias. 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; he’s 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.
