We Are Third Streaming.



Founded by Yona Backer, Third Streaming Advisory Services (3SAS) has nearly twenty-five years experience working with nonprofit arts institutions and in philanthropy with a specialization in artist and artist-centered institutions. Backer has a compelling track record of providing strategic guidance and implementation plans, assessing and designing programs, coaching nonprofit leaders, and managing complex planning efforts to affect change and meet mutually agreed upon goals.

Backer has developed a uniquely, global perspective in her philanthropic practice.
