Beginning with the first “School for Tree Wardens” in 1913, the MTWFA has sponsored training and continuing education for those involved in arboriculture across the Commonwealth. In 2003, the association formalized the offerings as the Professional Development Series (PDS).

A PDS topic may be a one-time, occasional, or annual offering. Trainers and educators come from both the public and private sectors.The training workshops are designed to benefit

  • tree wardens
  • crews from municipal departments such as public works, forestry, parks and recreation, and cemeteries
  • owners and employees of commercial tree care and landscape companies.

Look for notices of PDS workshops on this website, in the BARK newsletter, in email notices sent via Constant Contact, and occasionally in regional industry-related publications.
