Susan Hawes - Johnson Creek Watershed
Parks and natural areas in inner SE and outer SE Portland
Susan works with partner organizations and volunteers in the Johnson Creek Watershed in southeast Portland. Susan has a bachelor's degree in Cultural Ecology from Linfield College, performed botany surveys in the Pacific Northwest for more than ten field seasons, and has managed volunteers for land management-oriented non-profits and government entities since 2000. Susan also volunteered for AmeriCorps for two years in the Portland-Vancouver area and became familiar with many of Portland's natural areas during that time. Growing up in the woods of the Pacific Northwest cultivated her love of everything outdoors, and she is inspired to share this with fellow Portlanders. She likes to garden, fiddle, hike, backpack, botanize, give massages (she's a state-licensed massage therapist), and play with her cats, Scout and Middie.

Mary works in parks on the west side of the Willamette River. She has a bachelor's degree in Environmental Studies from Keene State College and has been engaging youth in environmental education and restoration projects in Oregon with non-profits since 2007. She has been working closely with the PP&R No Ivy League program since 2008 and currently manages this program. Mary enjoys connecting and educating youth and volunteers of all ages to Portland's natural areas while seeing ecological transformations occur in our parks. In her free time, Mary enjoys gardening, backpacking, canoeing, cooking, and listening to live music.

David Grandfield - Willamette River Watershed
Parks and natural areas close to the Willamette River
David joined Portland Parks & Recreation in the summer of 2015 as a Seasonal Maintenance Worker for the East Side Natural Area Stewardship and Regional Trails Programs. In the summer of 2015, he was the Tree Crew Leader for PP&R’s Youth Conservation Crew. After completing the YCC season he joined Urban Forestry’s Outreach and Education team to draft YCC reports and create work plans for future YCC crews. In 2017, he accepted a limited term appointment as a horticulturist with horticulture services. For 14 months, David managed the maintenance and design of the “Mall Pot” flower and perennial planters downtown along the TriMet MAX line, as well as Union Train Station.
Since joining PP&R, David has been inspired by our equity and inclusion goals. He hopes to continue to be a mentor for youth in our Environmental Education programs. David holds an associate’s degree in Botany from Lane Community College in Eugene, as well as a horticulture degree from Oregon State University in Corvallis. His long term professional aspirations are to continue connecting marginalized groups to nature, urban ecology, food production systems, and land stewardship. He spends his free time sewing clothes, performing with a vogue-style dance team, and competing in Portland’s queer ballroom scene.
