Mosaica Announces
Selection of New President/CEO,
Retirement of Founder

Mosaica: The Center for Nonprofit Development and Pluralism has hired a new President and CEO, Rachael Coleman Gibson, who will assume responsibility for this multicultural, values-based nonprofit consulting groupJanuary 1, 2012. Rachael will succeed Founder and President Emily Gantz McKay, who has led the organization since its inception in March 1994.
"The Board of Directors is delighted that Mosaica will be led by a brilliant, deeply committed professional who shares our organizational values and is skilled in team-based management and consulting services," said Board Chair Alejandro (Alex) Perilla, Director of the Arizona State University Center for Community Development and Civil Rights. "Rachael served for three years on Mosaica's senior staff before moving to the Community Foundation for Montgomery County's Nonprofit Advancement Fund. She has strong credentials in providing organizational development assistance to community-based nonprofits as well as working with foundations. Rachael understands Mosaica and the unique role it plays in metropolitan Washington, nationally, and internationally."
Rachael is a Jamaican immigrant who received a Bachelor's degree from the University of North Florida and a Master's in Community Planning from the University of Maryland, College Park. She says, "I am honored to be given this opportunity to lead an organization that has had such a monumental impact on the nonprofit sector locally, nationally, and internationally. I am committed to upholding Mosaica's values and preserving the organization's longstanding reputation
for providing high quality support to nonprofits."
"Mosaica has undergone a three-year planned transition process culminating in the hiring of Rachael," Alex explained. "We are also delighted that founding President Emily Gantz McKay will continue to serve as a Senior Consultant on selected projects, while pursuing a wide range of other interests."
"The staff is delighted with the Board's decision to hire Rachael," Emily explains. "I have every confidence she will take Mosaica to new levels, while maintaining our passion for social justice and our commitment to excellence. Mosaica was established as a nonprofit because we deeply believe in the critical role played by nonprofits - and the public agencies and private funders that support and collaborate with them - in strengthening communities and creating societies that value and embrace multiculturalism. It has been a privilege to guide the work for nearly 18 years, and a joy to know that we have strong staff and leadership for the future."
Mosaica will be moving from its long-time home at 1522 K Street to 1029 Vermont Avenue, NW when its lease ends December 31.
Emily will do independent consulting and will serve as a Senior Consultant to Mosaica on several projects, most of them involving HIV/AIDS or the health care safety net. "I will be renting office space far enough away from Mosaica to ensure that I have no engagement in its management and decision making," she says. "I also hope to spend more time doing volunteer work here and with social justice nonprofits in Israel, and perhaps training nongovernmental organizations in the Dominican Republic, where my former boss at the National Council of La Raza, Raul Yzaguirre, is now ambassador."
Mosaica exists to provide tools to nonprofits to build just, inclusive, and thriving communities and societies. Its special commitment is to organizations that serve populations whose voices are least likely to be heard when policies are made and resources allocated - such as communities of color, immigrants and refugees, people living with HIV disease, and low-income women. It is known for its team-based services, multi-cultural and multi-disciplinary staff and Board, and unwavering commitment to quality.
