The half-day sessions were very popular with attendees at the inaugural conference, we are again looking for groups who may be interested in self-organizing a session to provide an in-depth perspective and/or training on a topic of significance to permit holders across the state. Please contact Laurie Larson at 253-445-4593 if you would like more information on how to develop your proposal.
