Mark Walton, Publisher of the Art Glass Quarterly is a well known San Francisco Bay Area art glass designer, instructor, author, and artist. Since 1972, Walton Art Glass Studios has designed and created art glass windows that are seen in homes and businesses throughout the world. Working extensively with Walt Disney Imagineering, he has designed windows for Disneyland in Anaheim, California, Tokyo, Japan, and hundreds of windows for Disneyland Paris, France.

Mark and his wife, Susan are the authors and publishers of three books on stained glass design and one textbook on art glass. He has written numerous articles on Art Glass over the past three decades.

Curt Walton, Editor-in-Chief of Art Glass Quarterly, is thrilled to be back in the publishing industry. He has worked extensively the fields of art and music since 1974 when he started working with Mark in the Art Glass business.

In March of 2001, he founded FreeHand Systems, Inc. creating the MusicPad Pro, the first electronic sheet music tablet / management system that solves the age-old problem of page turning during musical performance or rehearsals. This very successful company now owns the largest digital music library in the world.

Bob Cullen is the managing editor of the Art Glass Quarterly. He became interested in glass when restoring a 100 year old historical building designed by Julia Morgan (which is the home of Art Glass Quarterly.) The leaded glass windows in the building needed repair. He and his wife, June, met with Mark and put together a plan to restore the leaded windows. Little did he know that it would turn into a business opportunity as well. Not only did they end up putting together a plan to restore the windows; they also met with Curt and ended up putting together the business plan that helped launch Art Glass Quarterly.

Bob is an attorney (doesn't he look like one) who previously practiced law with Hoge, Fenton, Jones & Appel, Inc., a 50-attorney law firm located in San Jose, California. He received his Bachelor of Art degrees from the University of California at Santa Barbara. Bob graduated from Hastings College of the Law in San Francisco, California.
