Commercial Horticulture Team

Vermont’s horticultural farms are diverse (PDF), with many types of crops, production systems, markets, and growers. Our team uses multiple communication channels and educational tools to build social capital in the community while providing technical support to address an array of needs identified by growers and/or required by regulations. This approach focuses on sharing best practices developed by growers and people that work with them.

Our Team

  • Chris Callahan, Agricultural Engineer, leads the Agricultural Engineering program, provides growers with guidance on high tunnels and greenhouses, post-harvest facilities, renewable energy, and more. He also leads the Northeast Center to Advance Food Safety (NECAFS) which supports education and outreach related to the FSMA Produce Safety Rule and Preventive Controls for Human Foods Rule.
  • Julie Callahan, Farmer Engagement Specialist, helps growers understand, and when appropriate, apply to state, federal and private funding programs that can provide financial support for sustainable production practices and infrastructure investments needed to help their farms thrive.
