a bit about FSD

Len Stubenfoll learned the ropes of toy Invention at the legendary Marvin Glass & Associates in Chicago, IL. 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 in Oak Brook, Illinois, where he is located to this day.

Working in all areas of toys and juvenile product, FSD Group LLC has licensed products to toy companies around the globe.
