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.
