Thank you for your question. Since you are mainly dealing with an emerald ash borer education program, I have several suggestions for you. The Minnesota Department of Natural Resources has a Tree Inspector program which will provide education opportunities. Here is their website:

Also, contact your city of Waconia. If they have a Parks Department, they may have a person who can attend your meeting and answer your questions. They also may have a certified arborist on staff that may help you. 

The University of MN Forestry Extension office offers education programs. Here is their website:
