Our Board of Directors


Peter Wynnyczuk, Executive Director

Jose Rubio Lazo

Peter W.Peter has been involved in Urban Forestry for over 30 years at the municipal level and is the previous president of the Ontario Shade Tree Council (now the OUFC!). He has also been supportive of Arborist-related committees and activities. Peter is the retired urban forest supervisor with the Town of Richmond Hill. joseNomar Jose Rubio Lazo, known to most as “Jose the Arborist,” runs a small practice in downtown Toronto, and consults extensively to government and business in Central America. His indigenous background and hands-on experience with native approaches to agriculture have shaped the integrative way Jose cares for trees. Simplicity, common sense, and working in harmony with Mother Nature, he believes, is just as important as science and sophisticated technology.  Jose studied History at U of T and arboriculture at Humber College.  He is ISA certified as an arborist and as a tree climber specialist.  Jose also holds the ISA TRAQ qualification in risk assessment, and is an OUFC Heritage Tree Inspector.  His work has been featured in ISA and industry publications.  Jose was nominated by his clients and became a finalist three years in a row for the ISA’s True Professional of Arboriculture Award. He subsequently declined to stand for the award, believing that the finalist pool needs to be kept fresh with new faces in the field.  Jose is a candidate in Environment and Sustainability Studies through Harvard University’s Professional Certificate Program, and has been active at Harvard’s Arnold Arboretum for years.
