Maria Foscarinis
Founder & Executive Director 


“My family suffered terribly during the German occupation of Greece in World War II, and as a child I heard my parents’ stories of starvation, deprivation and loss—as well as courageous resistance—on an almost nightly basis. I wanted to use the relative privilege of my life to fight for a world where no one has to suffer the injustice of dire poverty.” 

In the mid-1980s, Maria was a litigator at a large corporate law firm where she volunteered to represent homeless families on a pro bono basis.  After seeing the impact of first-rate legal advocacy on the lives of homeless people, she left the firm to dedicate herself to that work full-time.  In 1989, she established the Law Center with one goal in mind: ending homelessness in America.

Maria has advocated for solutions to homelessness at the national level since 1985.  She is a primary architect of the Stewart B. McKinney Homeless Assistance Act, the first major federal legislation addressing homelessness, and she has litigated to secure the legal rights of homeless persons. Maria has written widely on legal and policy issues affecting homeless persons; her work has appeared in scholarly as well as general audience publications. She speaks and lectures regularly on law and homelessness, conducts trainings on legal issues and advocacy strategies, and is frequently quoted in the print and electronic media.

Maria is a 1977 graduate of Barnard College and a 1981 graduate of Columbia Law School. She also holds a M.A. in philosophy.
Diane Aten
Director of Development & Communications

“I care deeply about social justice and truly believe that it is possible to end homelessness. I also believe in the power of working together. Every one of us, doing our part and taking combined action, will generate a powerful, collective impact. Growing up in Washington, D.C. and attending very diverse, public schools helped shape who I am today.”
Diane Aten has a passion for organizations that provide affordable housing, services, and opportunities for low-income people. For more than twenty years, Diane has worked in development and direct service for nonprofits including Montgomery County Coalition for the Homeless, Samaritan Ministry, Sojourners, Friendship Place, and Threshold Services.
Diane’s extensive development work includes online and monthly giving, corporate relations, major gifts, grant writing, and direct mail appeals. She also has considerable experience in managing special events, volunteers, as well as in-kind (non-financial goods and services) donations, communications and media relations activities.
Diane received her undergraduate degree in Psychology from the University of Maryland, College Park in 1991. She also holds a master’s degree in not-for-profit management.
Tristia Bauman
Senior Attorney


“As the daughter of a disabled father and an immigrant mother, I grew up poor and I know well the barriers to success imposed by poverty. I became a public interest attorney, and the Housing Program Director at the Law Center, to break down those barriers and to provide every person – people just like me – with the chance to thrive.”

Tristia Bauman combines litigation, legal education, and legislative advocacy strategies to prevent and end homelessness. Her work focuses on combating the criminalization of homelessness and advocating for laws that protect the civil and human rights of homeless people. Tristia also conducts legal trainings around the country, writes reports and other publications related to housing, and serves as a legal resource for homeless advocates.

Tristia began her law career at Legal Services of Greater Miami, Inc. as a housing attorney working with low-income tenants in federally subsidized housing. She later served for several years as an Assistant Public Defender in Miami-Dade County.

Tristia hails from Auckland, New Zealand but was raised in Washington State where she attended the University of Washington as an undergraduate and law student. She received her B.A. in Anthropology in 2000 and her J.D. in 2006.
Janelle Fernandez
Law & Policy Program Associate 


“I want to help create the political will and public momentum to ensure that everyone has food, shelter, and education. We have the resources to achieve this; we now need to summon the collective strength and courage to see it through.”
Janelle Fernandez, Law & Policy Program Associate at the Law Center, provides programmatic and administrative support to the Law & Policy team. Janelle brings extensive experience to the Law Center, primarily in data management, system development, process improvement, project management, and capacity building. At the Law Center, she assists the Policy Director with legislative tracking and the development of Law & Policy outreach materials and strategies. She also manages the Law Center's internship and fellowship program, provides support to the pro bono program, and co-facilitates presentations at law firms, conferences, and other venues to gain support for the Law Center's projects. 
Janelle cultivated an interest for policy work as an undergrad at Florida State University, where she received a Bachelor’s Degree in Sociology. Before coming to the Law Center, she worked in the private sector as a program analyst. Currently, in addition to her work with the Law Center, she is an active volunteer in the DC chapter of RESULTS, an anti-poverty policy advocacy organization, focused on specific long-term solutions to alleviating the root causes of poverty, primarily in the areas of education, health, and social/financial mobility.
Sarah Knutson
Development & Communications Assistant 


“We do not have to relegate ourselves to a society that does not value all of its members, that does not provide equal opportunities for its citizens, and that accepts systemic neglect as the status quo. As Americans we hold a unique power to affect change, to see injustice and challenge it. I want to be part of a society that expects more from and for its people.”

As the Development & Communications Assistant, Sarah takes on tasks that support and shed light on the important work of the Law Center. Her most important role is acting as an advocate for those living without a home and without the legal clout to defend their rights.

Her passion for social justice took root during an internship with the Pennsylvania Literacy Corps. She was able to tutor GED and ESL adult learners while also researching the history and politics of education and exploring literacy’s relationship to class, gender, and ethnicity. It was then that she witnessed the value of coupling the right resources with people who, until that time, were certain they were incapable of success. She let the experience inform her commitment to building communities through service projects and connecting nonprofits with the right resources to make a difference.

Sarah graduated from Penn State University with honors in two degrees, a B.A. in Philosophy and a B.S. in Mathematics.

LaTissia volunteers with Free Minds Book Club & Writing Workshop. She holds a M.A. in English from the University of Michigan, and a B.A. in Comparative Literature from Stanford University.
