Board of Directors

Originally from Brooklyn NY, I spent my teen years in Ridgefield CT. After attending 2 different schools, I landed at NYU to finish my degree in English Lit and Political Science. I worked on Wall Street to support my way through school. I was in the first class in which trading options was part of our licensing curriculum. In hindsight, it was my first exposure to gambling. I received my master’s in Urban Planning at Hunter College, after spending time volunteering in NYC homeless shelters and wondering why we had such a scarcity of affordable housing. As a planning consulting I worked on housing, environmental sustainability and too many variances for MacDonald’s. Realizing the NYC area was just too expensive, my husband and I moved to Minnesota in 1992, childless and jobless, seeking an affordable and vibrant place to set down roots. After a few years of being home full time with our two daughters, I have served organizations whose missions I could support and help grow. I am active in our church, we love to travel, cycle and I am an avid gardener with an Elmer Fudd complex.

Living in the beautiful Pacific Northwest for 27 years had made this truly Home for me. I grew up in the Midwest — Kansas City, Missouri. A passion for conservation led me to San Diego, CA, where I worked at the San Diego Zoo and the San Diego Wild Animal Park for 12 1/2, first as Assistant Editor of ZOONOOZ; then in Conservation Events and Development/Fundraising for the Center for the Reproduction of Endangered Species. The Wolf’s call led me to Washington State in 1993, where I was Executive Director of a Wolf Sanctuary for six years. The Lottery was my next career move and it opened up my eyes to both the benefits and the potential harms of gambling. The Washington State Council on Problem Gambling was my first client when I opened my own business to assist small nonprofits with communications and fundraising. When they asked me to step in as Executive Director a little more than 3 years later, I joined a wonderful team of passionate Board Members and an organization without much funding, no office to call home, and no other staff. Today, we still have a passionate and talented Board and an equally passionate and talented staff. We have an office (though, like so many, we are working remotely right now).
