Empowered by Artists.

Third Streaming Advisory Services (3SAS) is a New York City–based global consultancy that supports nonprofit and philanthropic organizations working in the arts & culture sector. Our work often intersects with the social justice field. Rooted in over two decades of hands-on experience, we augment our projects in cross-sector research and close collaboration with our clients. Yona Backer, the principal, provides strategic guidance and planning to nonprofit leaders, mentorship, and staff/board training as well as program development and evaluation; research; development strategies and fundraising campaigns. Through a collaborative process, we create strategic Roadmaps that visualize and communicate our client’s goals and aspirations: strengthening organizational capacity, deepening impact, and increasing efficiency. What drives us is our aim to generate greater social awareness and to make our world a better place for all. As a strategy and leadership expert, Backer also works with artists and artist estates on legacy planning. We advise individuals to think through their charitable giving. 3SAS manages The Alvin Baltrop Trust.
