Development Team

Vaughn-MauriceVaughn utilizes his lengthy experience in community outreach, leadership, program development, public speaking, and philanthropy to help ALDF provide the best possible legal advocacy for animals serves as a liaison between donors and ALDF staff. He draws upon a great wealth of creative and analytical skills to make a positive and progressively-responsible impact upon the organization, and serves as a liaison between donors and staff.

Prior to his work at ALDF, Vaughn served as general manager of Dogs for the Deaf, a nonprofit organization that rescues dogs and trains them to assist hearing impaired people. While in that Oregon-based office, he managed a staff of 31 and significantly increased revenue for that organization. Vaughn also served as executive director of the St. Tammany Humane Society in Louisiana where he worked on the successful campaign to end cockfighting in that state (the last state to do so), and in various development roles for the American Red Cross for more than thirteen years.


William Rivas-Rivas represents ALDF to our major donors and is responsible for developing major philanthropic support to ALDF. His exceptional talents include an empathic and passionate ability to engage with donors and serve as a liaison between donors and ALDF staff. He delights in being able to thank ALDF’s generous donors for their support, being in the unique position to extend appreciation for their kindness, and hearing wonderful success stories which makes ALDF’s work possible.
ALDF is a true fit for the genesis of William’s beliefs in animal protection. As he says, “If you are seeking justice for animals, there is no better place than ALDF.” He is a strong believer that people with particular skill sets should employ their talents in consideration of what’s best for animals, not themselves. Before joining ALDF, William spent several years as Manager of Donor Communications and Relations at the American Red Cross National Headquarters in Washington, D.C.

William began his career in animal advocacy at PETA, where he spent nearly 6 years involved in protests against such organizations as the Ringling Brothers, and started PETA en Español, an animal rights campaign in Spanish. After returning to his foundation in development campaigns, William later became a major gifts officer at the PETA Foundation. He holds a bachelor’s degree in Political Science from the University of Houston and an international master’s degree in Photojournalism from Spéos, where his unusual animal-as-food photography won him special notice in a juried exhibition.

A proud Texan, William was eating his way through the animal kingdom, until one day he went from being a heavy meat eater to a vegan overnight. He made this ethical transformation while in the U.S. Navy, where he spent nearly a decade “sailing the seven seas,” four years of which were spent as a Naval Officer, stationed on two warships, including an aircraft carrier. After witnessing “might makes right” mentalities go awry, William has been a vegan for 16 years.

William lives in Oakland, CA with his partner, Rachel and super-sweet feline rescues, Marmus, Sumalee, and Sophie. In his free time, he enjoys photography and is an award winning photographer as evidenced on www.williamrivasrivas.com. He also enjoys long-distance running. He recently ran a double marathon, raising over $12,000 thousand dollars for ALDF and the protection of animals.


Emily MillwardAs an administrative assistant for ALDF’s Development program, Emily assists with donor support, community outreach, program development, public speaking, and philanthropy to help ALDF provide the best possible legal advocacy for animals. Emily helps thank ALDF’s generous donors for their support, and she extends our appreciation for their kindness in helping to make ALDF’s work possible.

Emily has worked for nonprofits previously, including for animal shelters and organizations working with at-risk youth. In 2013, she interned for Canine Companions for Independence and knew she wanted to focus her career on helping animals—for her, helping animals has always been a central part of life. She brings strong written and oral communication skills to this position—a Sonoma, California native, Emily received her bachelor’s degree in communications in 2013 from California State University, Chico, where she majored in Communications and minored in Marketing. She is the first person in her family to graduate college and is a first-generation American citizen.

Dale ThompsonDale works closely with the director of development in day-to-day operations and specializes in grant writing. She received her undergraduate degree from Evergreen State College, where she developed a passion for animal rights and environmental conservation. She later completed a master’s degree in professional communication at Westminster College.

Previously, Dale worked with the Great Salt Lake Institute in Utah, an organization dedicated to supporting research, education, and stewardship of the Great Salt Lake. This is a vital migratory habitat for birds designated as part of the Western Hemisphere Shorebird Reserve Network in 1992, and Dale is proud of the work she did to help people understand the value of the lake and the wildlife who rely on the lake habitat for survival. Conservation is important to Dale’s animal activism and she has worked for another organization that protects wilderness areas and endangered species—in addition, Dale has volunteered with the Great Salt Lake Audubon Society. Dale also has a background in the arts, having previously worked for a performing arts center and an online arts magazine.
