Georgie Donovan
Georgie comes to the BDA after 20 years in academic libraries and higher education, most recently as associate dean at William & Mary Libraries in Williamsburg, Virginia. Her academic career focused on organizational development, budget and finance, EDI (equity, diversity, and inclusion) issues, and assessment: all interests she hopes to bring to her work at the BDA. This year, she moved to a small trailer on the organic Demeter certified Biodynamic farm, Against the Grain, in Zionville, North Carolina, where she and her husband, M Mueller, have become part of the farm family. Her dedication to biodynamic agriculture grew as a result of attempting to live in service to the honeybee. She and her husband have been working with bees for a decade, studying beekeeping under the teachers at Spikenard Honeybee Sanctuary and sharing the joy of swarms, wildflower cultivation, and observation. In fact, she might say that all of the wanderings she has had — whether in music and dance, travel, poetry, yoga, painting, herbal healing and ayurveda, cooking, love and family — all can be seen through the lens of learning the language of the bee.

Anna McAvoy-Emrick
Anna has made a career of helping build organizational capacity in her various nonprofit roles over the past 11 years. She enjoys seeing the organization flourish in new ways once a more solid foundation has been set up with process, procedure, and efficiency of task management. In her roles with the BDA, she has additionally been able to experience the joy, freedom, and challenge of building People processes (human resources) that center on the humanity of the person, and of co-creating an organizational culture that best serves the individuals working here. She earned a B.S. in Nonprofit Management from Manchester College (now Manchester University) and lives in Holt, MI with her husband and child, on land formerly stewarded by Odawa, Peoria, Anishinabewaki peoples.

Anthony Mecca
Anthony Mecca has been farming for 15 years, being introduced to biodynamics early on and working with many experienced farmers and mentors. He has worked in market gardening, small grains, and perennial crops including berries and tree fruit. For 8 years, he managed his own diversified CSA farm. He has also cared for a variety of animals, including the use of draft horses as the main source of power, a 15 cow herd on his diversified CSA farm, and more recently working on a raw milk dairy. The farm and garden as a center of community life is pivotal in his work. Bringing people into relationship with the wonder, beauty, and nourishment a biodynamic farm can provide, and seeing them grow and develop through this relationship individually and in community over the years has inspired his work. Anthony has recently developed a year-long course on Biodynamic Agriculture and Nutrition available through EduCareDo and through the Biodynamic Association’s Development Year Farmer Training Program. In addition to this course and his farmer training work with the BDA, he offers workshops, mentorship, training, and consulting near his home in the Hudson Valley of NY and beyond, in person and remotely, and would love to support biodynamic agriculture and nutrition developing on your farm, garden, or community.

Kerri Quinlan
Kerri brings a deep appreciation for food, nature, people and spiritual growth to her work with the Biodynamic Association. She spent her formative years in Vermont's Northeast Kingdom, amidst forests and farm land. Gardening, berry picking, maple syrup harvesting, and hayloft jumping are among some of the best memories of her childhood and she always wished she grew up on a farm. Kerri has a Bachelor's Degree in Psychology from Western Colorado University, and spent the past decade supporting equitable health and educational access through grant writing, program development, and administrative oversight. She is excited to bring her skillset to supporting the mission of the BDA as a steward of its financial health. Kerri recently relocated to Portland, Oregon to follow her dream of studying Liberation Acupuncture at POCA Technical Institute, and lives on land originally stewarded by the many tribes who lived and traveled near the Willamette and Columbia rivers; including the Clackamas Chinook, Multnomah, Willamette Tumwater, Wasco-Wishram, Tualatin Kalapuya, Cayuse, and others. After many years of living at 10,000 feet in the mountains of Colorado, she is really excited to have a low altitude garden.

Grace Stepanova
Scholarship Fund, Administrative Assistance
Duvall, WA
Grace Stepanova
Grace joins the BDA with a not-yet-fully-understood soul connection to biodynamics and anthroposophy. Her initial encounter with Steiner and his teachings comes out of an ever-unraveling desire to understand the mysteries of food, to the core. She has spent the last decade exploring the many facets of food, predominantly in the realms of agriculture and nutrition, with seemingly inconsequential, yet formative experiences in food law and policy sprinkled about. Her long-standing health complications have also served as a guiding force, assisting her towards further alignment with her desires to live in honor of and reciprocity with the Earth. She and her husband are intent on further developing an interest in traditional skills and ways of existing in harmony with the Earth. They hope to nurture a balance between a careful tending to and cultivation of the Earth, and a more ancestrally guided interaction and communication with Earth as wilderness. Outside of her involvement with the BDA, Grace is mother to a blossoming practice in functional nutrition and is stepping more firmly into a call to birth work, which in her eyes dances intimately with the core essence of food as life, both for humanity, as well as for the Earth. She holds a B.S. in Environmental Science from the University of California, Davis.
