About the Organization

Shared Horizons is a 501(c)(3) nonprofit organization created to manage Pooled Special Needs Trusts. Our goal is to protect public benefits, provide goods and services, and preserve assets and funds. We are also required to payback Medicaid, if applicable. 

What We Manage

The nonprofit currently manages two trusts:

  • The Wesley Vinner Memorial Trust (self-funded)

    • Medicaid approved in DC, MD & GA

  • The 3rd Party Community Trust

Both trusts are designed to improve the quality of life for people with disabilities, while protecting assets and benefits.

Our funds are managed by Merrill Lynch, with the Kishtner Group as our fund manager.


The initial Trust was named in honor of Wesley Vinner, who was a strong, committed self-advocate who lived over 15 years at Forest Haven. He worked with many advocacy and disability rights organizations advocating for people with disabilities in the District of Columbia to lead meaningful, productive lives in the community.


Wesley wanted all people with disabilities to receive quality services in a timely manner from the agencies created to serve them.
