I'm a commercial arborist with over 25 years of experience in the East Bay.  I've also been incorporating aspects of permaculture design into properties where I do tree work—graywater systems, swales, agroforestry, bee and wildlife forage plantings.  I use biodiesel and VegOil in place of petroleum in my work equipment.  Later in the day, I sing and play guitar with like-hearted folks.  Originally I'm from New England; my BA from Clark U. included botany and taxonomy.
