Regional groups are an ideal complement to your AHTA membership. Connecting with other horticultural therapy professionals in your area enables you to exchange ideas, participate in group events, and network with a variety of colleagues. Regional horticultural therapy groups are doing excellent work for their members and their regions!

Please contact the regional horticultural therapy groups in the following areas to learn more and make sure to check their websites for upcoming events in your area.

Regional Horticultural Therapy Networking Groups Guidelines and Criteria:
Regional Horticultural Therapy Networking Groups are defined as groups that support the mission of the American Horticultural Therapy Association (AHTA).

  • Networking groups are independent groups.  There is no legal/business link with the AHTA.
  • The AHTA does not oversee, monitor, nor manage the membership of the networking groups.
  • The AHTA will list the networking group and contact information on the AHTA website.
  • Networking groups that do not have a designated nonprofit status will be identified by their region or state.
  • The designated group contact is required to be a professional member of the AHTA.
  • The AHTA will post networking events on the AHTA Calendar of Events and share information through the AHTA social media platforms.
  • Networking groups may not use the AHTA logo or name without prior permission.
