A Little Bit About FSD
Welcome to Fun
Len Stubenfoll learned the ropes of toy invention at the legendary Marvin Glass & Associates in Chicago. In 1989, after a short time with Breslow Morrison & Terzian (now Big Monster Toys), he teamed up with former Marvin Glass managing partner Harry Disko to form FSD Group LLC. FSD Group works in all areas of toys and juvenile product, licensing products to toy companies around the globe.
