TreePhilly’s Realtor Advisory Committee

TreePhilly’s Realtor Advisory Committee convenes before each giveaway season to strategically engage new homeowners in our Yard Tree Giveaway program. Philadelphia realtors donate their time to promote TreePhilly to their clients by distributing literature and social media messaging about how new homeowners can receive free trees for their property.

Realtors of the month: Margaret and Tom DelColle

Margaret and Tom DelColle have been avid gardeners for almost 25 years. (Margaret brought gardening to the relationship and Tom embraced it immediately.) They always felt that there should be more green space in Philly, so they became involved with greening efforts through the Pennsylvania Horticultural Society Tree Tenders Program. They have been personally involved with planting over 100 trees in their neighborhood. They continue to stay involved as PHS Tree Tenders and members of TreePhilly’s Realtor Advisory Committee, and they hope to see an even greener Philadelphia.

Other realtors participating in the advisory committee include:

  • Bruce Benjamin Philly’s Best Address
  • Marcello Ciurlino Philadelphia Living
