Purpose Built Families Foundation’s Operation Sacred Trust (OST) program is a nationally accredited, collaboration for homelessness prevention and rapid rehousing. Fundamental to the approach of OST is attention to factors that create, contribute to, and address challenges to housing stability for low-income Veteran families.


Founders Stephanie Berman-Eisenberg and Seth Eisenberg envisioned Operation Sacred Trust as a collaboration of nonprofit service providers committed to exceptional service, supports and resources for homeless and at-risk Veteran families. Since 2011, the program has disrupted and prevented homelessness for thousands of Veterans and their family members in South Florida.


Yamaris Quiles Arbitman joined the Operation Sacred Trust team in 2014. As Program Director, she oversees client services for Veteran families in Broward and Miami-Dade counties. Yamy led the agency’s successful efforts to pursue CARF accreditation.
Julie Macias joined the Operation Sacred Trust team in 2013 as a Case/Care Manager. She quickly became a team leader, deputy program manager, and training director, consistently demonstrating exceptional leadership, mentoring, and technology abilities.
