Joyce White

Executive Director

Joyce White JOYCE WHITE is the executive director of GRANTMAKERS of Oregon and Southwest Washington. In 1999, she was asked by Oregon funders to start a regional association of grantmakers and join a network of 32 similar organizations across the country with connections to the national philanthropic sector. One of her first assignments was to manage the Oregon plan of the Northwest Giving Project, one of the many initiatives to grow philanthropy under the banner of the national New Ventures in Philanthropy. From the very beginning, her work in philanthropy has been both local and national.

Joyce has a long history of work in the nonprofit sector. Just prior to coming to GRANTMAKERS, she spent nearly a decade developing heritage tourism projects on Oregon’s four national historic trails, working closely with Oregon’s economic development and tourism departments and rural and Tribal communities. “Almost” an Oregon native, Joyce has served on many nonprofit boards focused on a broad range of interest areas: women and children; the arts; historic preservation; economic development and volunteerism.

As the Executive Director of GRANTMAKERS, she served on the board of the Forum of Regional Associations of Grantmakers and an advisory board for the LearnPhilanthropy project of the Johnson Center for Philanthropy in Grand Rapids, Michigan. She was awarded a lifetime achievement award by the Willamette Valley Development Officers.

In her spare time, you can find her on a trail in the Columbia River Gorge or with a good book on her deck. When bored, she taps the youthful energy of ten grandchildren all living in Oregon.

Maddelyn High

Program & Membership Manager

Maddelyn High MADDELYN HIGH is driven by the desire to continuously learn from the nonprofits and funders working to transform the Pacific Northwest for the better. Most recently, Maddelyn was grants manager at Meyer Trust, where she supported a large portfolio of grantees. Prior to Meyer, Maddelyn worked in education and book publishing. [She received a graduate certificate in nonprofit management from University of Oregon, and a BA in English and Sociology from University of Wisconsin-Madison].

Of working with GRANTMAKERS of Oregon and Southwest Washington, she says, "GOSW has been such a valuable resource for me as a grants manager -- both when I was new to philanthropy and as a seasoned practitioner. I’m happy to be able to offer support, encouragement, and understanding within our region’s community of funders, and I’m inspired by the potential members have to enact real, positive change in our communities."

Rhiannon Orizaga

Communications & Administrative Coordinator

Rhiannon Orizaga RHIANNON ORIZAGA joined GRANTMAKERS in 2015 and moved into the newly-created role of Communications and Administrative Coordinator after a year. Like many nonprofit unicorns, she is a wearer of many hats: program and office administration, knowledge management, member support, communications, and technology form the core of her work, but there are always new moles to whack, and she embraces the opportunity to stretch her mallet hand with special projects.

Rhiannon attended Oregon State University, where she received a double Bachelor of Arts in English and History. After that, she earned a Master of Arts in Ancient History from Portland State University, with an emphasis on Identity Politics in Early Imperial Rome. She also published an article on the subject, in Tattoos and Body Modifications in Antiquity.

In her spare time, Rhiannon enjoys spending time with her wife, Sarah, and cat, Miso; knitting and crafting; and traveling. As the daughter of an immigrant from Mexico, she is passionate about equity, inclusion, and immigrant’s rights, as well as supporting small businesses and domestic violence prevention/amelioration.
