-At the Roosevelt Center for American Policy Studies, Mark designed role-playing simulations to engage the public and elected officials on burning issues of the day.

-As Vice President for Communications at World Wildlife Fund, Mark dramatically expanded awareness of WWF and the urgent conservation causes it works on.

-As an Internet communications guru since 1999, Mark has helped shape pioneering strategies and tactics for Environmental Defense Fund, the Monterey Bay Aquarium, the Sierra Club, Southern   Poverty Law Center; Christopher Reeve Paralysis Foundation; the Nature Conservancy; Amnesty International and the American Civil Liberties Union; and many others.

-A frequent blogger and speaker, Mark is in high demand for this creativity, his quick wit, his strategic insight, and his generosity.

Mark has a law degree from Georgetown and more recently a certificate in feature film screenwriting from University of California, Los Angeles (extension program).

He is a passionate diver, is in love with sharks, and is especially committed to marine conservation issues.
