Our conference theme “Cultivating Competence” operates on at least two levels, organizational and personal.  At both levels we want to develop and nurture the skills and abilities need to perform the tasks required of an arborist.  Programs like Certified Arborist, Certified Tree Climber, TRAQ, and CTSP connect the individual and organization.  Dr. Clark will argue that these programs are necessary to cultivate competence but not sufficient to achieve it.   Join us in May for this provocative discussion!
