Our studio was an Accredited Professional Studio Member of the SGAA from 1995

through 2004. We have voluntarily surrendered our Accredited Membership. As presently administered, we do not believe that professional accreditation in the SGAA is a true or meaningful measure of a studio's professional abilities or the quality of the work that the studio

will produce.
