Wade Arnold
Farm Manager
Wade is a longtime Washingtonian, spending most of his life as an Olympia resident, which is where he developed a passion for serving others. He began his career with GRuB as a Cultivating Youth crewmember in the summers of 2000 and 2001. From 2005-2007 he went on to serve throughout Washington as an Americorps member through the Washington Conservation Corps. Wade is now the first Cultivating Youth alum to be brought on as a core staff member of GRuB. Though his title and job description imply farmer of the land, he also provides staff support for the farming self and farming community of our Cultivating Youth Program. He loves the Mariners, working hard and getting dirty, and being deceptively silly.
Carolyn Cosgrove-Payne
Cultivating Youth Counselor
Carolyn recently graduated from Boston University with a BA in International Relations and has migrated across the country as GRuB’s new AmeriCorps member for the Cultivating Youth program. We’re so pleased that she’ll be joining us for a second year! She has previously worked for an assortment of community gardens, refugee resettlement organizations, and non-profits on the East Coast, and is slowly acclimating to West Coast culture (though for some reason she misses being shoved around every day on the subway). She likes things made out of chocolate, salsa dancing, the way that growing good food tends to also grow good humans, and daydreaming about her upcoming Peace Corps service. If you’re not careful, she will also quote poetry at you until your ears fall off.

Kerry has been a fan of and volunteer for GRuB for many years, starting as a funder through her employment with Lumbermens. Kerry enjoys dancing, morning runs, and grandchildren.

Before joining GRuB, he earned his Master’s in Non-profit Management and Leadership. Kevin is a pios man; strictly adhering to the tenants and philosophy of Indiana Basketball.

Before that, she graduated from Clark University with a BA in International Development and an MA in Teaching. Of all the things in the world to do, she most enjoys bringing people together with food. She brings her passion for community dialogue, teaching, and growing food to GRuB, with the hopes of making KGP’s evolution successful! She is repeatedly impressed with how nice West Coasters are and looks forward to new adventures in the Pacific Northwest.
