Horn Farm Board of Directors 2020From left to right, we are:

Erin Shrader – President

Erin is a native of Adams County, PA, where she grew up in the apple orchards of Gardners. Erin’s family worked the fruit orchards, picking apples and cherries, and also in the manufacturing of fruit into applesauce, pie fillings, etc at Mussleman’s Foods in Biglerville. As well as working in agriculture and the food processing industry, Erin’s family members were farmers since they arrived from Germany in the 1700’s, and probably farmed the land in Germany before their migration!
Erin’s grandparents were the last generation to devote much of their lives to farming. Modern convenience and large scale agriculture freed their time for other pursuits, but the love of tending to growing things remains strong.
Erin graduated from New Oxford High School after moving there from Gardners in eighth grade. She went on to earn her bachelor’s in nursing from York College. Erin worked as an RN for several of the area hospitals, as a school nurse for Bermudian Elementary, and as a hospice nurse at AseraCare Hospice. Erin’s passion for alleviating suffering gave her the opportunity to excel in her work in hospice, eventually becoming the Executive Director of the York agency.
The leadership skills that Erin honed in her role as Executive Director prepared her for her work in helping to establish the Bridges to Health program at Wellspan, co-founding the York Time Bank and leading the York Chapter of the Weston A. Price foundation.

Erin continues to be passionate about alleviating suffering, which she believes is done most successfully through education and access to healthy life choices. Erin spends most of her time these days homeschooling her children, teaching yoga, reading and finding ways to serve in her community. She is excited to have returned to her agricultural roots and to serve the community through the important work happening at the Horn Farm Center.

These additions improved the offerings that the Incubator Farm could extend to beginning farmers. As a longtime fan of wildlife, birds, hiking, gardening, landscaping, and all things outdoors, he was drawn to the Horn Farm mission and programs.

Allen Clements – Secretary

In 2017 Horn Farm Center offered an intensive course in Forest Garden Design with Dave Jacke which Allen attended. This course marked the start of Allen’s  deep dive into the study of permaculture and regenerative agriculture. It also marked the moment he committed himself to stewardship of the Horn Farm organization.

Since that time, Allen has become a certified biodynamic practitioner, is working towards a master herbalist certificate, and has produced over 20 videos about regenerative agriculture including several that showcase what the Horn Farm is doing. Allen is currently serving the second year of his first term on the board of directors.

Allen has a marketing degree and a background in design. He is currently working as a writer, director, and producer of films at MAKE films in Lancaster, Pennsylvania. As a student practitioner of permaculture, regenerative agriculture and biodynamics, he uses his filmmaking experience to produce video and online content educating and inspiring others who are becoming interested in these important topics.

Allen and his wife Kerry have four children. They enjoy gardening, raising chickens, beekeeping, and appreciating the beautiful trails and landscapes of Central Pennsylvania.

David Dietz
David Dietz has farmed in Hellam Township for most of his life. Growing up, he helped every summer on his parents’ truck patch farm, and he helped tend the roadside stand on the Lincoln Highway about a mile west of Wrightsville. Always interested in history, David earned a BSE in Social Studies from Millersville University in 1995, and spent several years teaching. Eventually, however, his love of the land drew him back to farming. In 2002, David started vending produce at York Central Market, where he continued until 2017. A founding member of the Horn Farm board, David helped start the Community Gardens and the Incubator Farm Project. Currently employed as the produce and dairy manager at Lemon Street Market in Lancaster, David is now interested more than ever in the challenges faced by local small-scale agriculture in a globalized commodity-driven economy. He is thrilled to see the Horn Farm Center leading with a vision for regenerative practices, learning from and working with nature. David is happily married to Waldorf teacher extraordinaire, Rochelle Dietz, and they have a delightful teenaged son, Gabriel.


David Freiberg
David Freiberg’s lifelong interest in agriculture started in his early childhood years growing up playing and learning at his grandparent’s farm in Chester County. This interest was nurtured during adolescence as he worked in his parent’s garden and orchard.

David received his BA in Business Administration from Bowling Green University in 1976 and subsequently a MPIA in Public and International Affairs from the University of Pittsburgh in 1978. During these college years David’s interest in environmental issues and food policies, especially in developing countries, continued to grow. After leaving Pittsburgh, David started his own business related to his other great interest: history. His agricultural enthusiasm persisted and he completed a one year course in biodynamics at the Sunbridge Institute in New York in 1999. He went on to receive an associate degree of biodynamic at Emerson College in Forest Row, UK in 2004.

He has a small homestead where he has been able to practice biodynamics during the past 25 years. He has grown a variety of fruits and vegetables and raised various livestock including a Jersey cow, sheep and chickens. David’s other passions include travel, gastronomy, history, beekeeping, hiking, and his family.


Julia Paris
Julia grew up on her family’s dairy farm in Bradford County Pennsylvania. She first became interested in horticulture while helping out on the farm. She cared for and harvested food for the livestock and also assisted with the maintenance of the family’s large vegetable garden. After graduating from Mansfield University, Julia began her career of coordinating services for people with development and intellectual disabilities. She currently works for Lancaster County as a Support Coordinator serving people with disabilities. Julia first discovered the Horn Farm Center after moving to Lancaster from Ithaca, New York.

Julia is a graduate of the Penn State Cooperative Extension Master Gardener Program and continues to provide horticulture information to the public through that program. She continues to search for educational experiences that will improve her knowledge of how to cope with our changing environment so that she can share it with others. Julia considers it an honor to part of the Horn Farm Center and its mission to have a positive impact and on both our local and global communities.


Michael Taylor
Born and raised in the City of York, Pennsylvania, Michael Taylor was introduced to gardening by his mother and has vivid memories of pulling carrots from their little backyard garden at the age of four. When Michael was six years old, his uncle started taking him on fishing trips, which allowed for an escape from the bricks, mortar, and noise of the inner city. Soon Michael would develop a love for rural landscapes, fields, ponds, rivers, streams, lakes, ocean beaches, bays, and woodlands. Sitting on a bank amongst reeds and cattails with fishing pole in hand, Michael experienced the peace of nature. Frogs, toads, snakes, birds, deer, fox, colorful butterflies, and insects of all types would present themselves to this young boy who had only viewed them on TV. Michael would often walk through the woods turning over logs and stones to reveal a world of exciting and strange organisms. This was also a great way to find fish bait! Michael was fascinated by the variety of plant life that surrounded him. His love for and interest in nature and gardening from childhood developed into an appreciation of our natural world, eco systems, and watersheds along with sustainable organic farming practices.
After graduating from York Catholic High School, Michael attended Indiana University of Pennsylvania, earning a B.S. Degree in Exercise Physiology with a minor in Sociology. Employed in the health and wellness field for several years before taking a position as a Health Educator for the York City Health Bureau, Michael would implement several initiatives, one of which was developing an urban community garden located in the city’s East End in front of the United Way of York. Michael also took a position at York College of Pennsylvania as an Adjunct Professor teaching courses in health, wellness, and fitness for eight years. Michael later returned to school and graduated from York College with a degree in Respiratory Care and began to practice as a Respiratory Therapist. Michael is currently the Director of Respiratory Therapy at a local hospital.
Michael began his relationship with the Horn Farm Center as a community gardener and later completed one season of the Horn Farm Centers Farm Internship Program (now known as the Regenerative Farming Training Program). Currently Michael continues to use the skills he learned growing food for his family as part of the Horn Farm community gardens. Michael focuses on practicing and experimenting with various no till and deep mulch methods of sustainable, organic farming. Serving as a member of the Board of Directors is a great honor for Michael and he looks forward to being part of the Horn Farm Center’s growth and continued positive impact within our community.
