I attended a post 21+ work seminar with the Museum Access Consortium (MAC) at The Met. MAC is an association that "regularly hosts professional development workshops and offers a network of mutual support to help practitioners engage with disability advocates and people who have disabilities to learn about, implement, and strengthen best practices for access and inclusion in cultural facilities of all types throughout the New York metro area and beyond."
I see this as having great potential for the employment and/or volunteering of our Developmentally Disabled population. I strongly suggest that you reach out to MAC for opportunities in their network, and you can contact:
MAC is sponsored by the FAR Fund which is "a private grant-making fund established in 2001 and located in New York City. The Fund awards grants to a diverse range of non-profit organizations that are working toward far-reaching goals in their efforts to support the social and emotional well-being of the people they serve."
