Frank Rinn, Founder of RINNTECH

This week's special guest, Frank Rinn, flew in to speak at the ISAO Educational Conference.  Born in 1963, Frank Rinn grew up in Heuchelheim, Germany. He studied Physics, Math and Philosophy at Gießenand Heidelberg University after having worked as a carpenter. He invented and developed different methods, machines, and computer programs for dendrochronology: resistance drilling, tree-ring measuring and cross-dating, dynamic tree analysis, and sonic tree tomography. Frank started his own company, RINNTECH, and developed equipment, including RESISTOGRAPH® and ARBOTOM®. Frank has been active in ISA since 2001.  Frank's educational presentations are in great demand worldwide, so we were thrilled when we were able to get him to sit down with us for a few moments to reflect on this journey in the Tree World.

Irina Souiki, Owner-Operator of Green Canopy Tree Services

ISA Ontario’s Roots and Rings is excited to introduce Irina Souiki, an International Society of Arboriculture Ontario-certified arborist and the owner-operator of Green Canopy Tree Services, based in Brampton. Irina represents one of the few women-owned tree service operations in Ontario — but her story is about more than breaking barriers. It began with a quiet calling. You’ll hear how she gradually drifted from the structured world of software engineering into the living, breathing world of arboriculture. She traded screens and gigabytes for harnesses and hardwood. Keyboards for climbing lines. Deadlines for tree lines. What began as a solo venture grew into a thriving company rooted in professionalism and best practices. Irina’s journey is a reminder that it’s never too late to change direction, to step outside, and to build something meaningful from the ground up. Her story is unique. Her path is courageous. And her enthusiasm for the trade is unmistakable.
