While POPAI chairman, Fellinger was instrumental in the establishment of the charter creating POPAI Europe.

In 2003, Fellinger and his wife, Stella, received the Arc’s Humanitarian Award and a commendation from the New Jersey State Assembly for their work with the organization.
The Fellingers have been advocates for children’s rights in special education for 20 years. In 2007, Mechtronics was recognized for Outstanding Service to the Developmentally Disabled for its ongoing corporate support of the Arc chapter.
