Are you CPR certified? Do you have first aid training?
Trinity is collecting names for a first response team who would be able to help out in case of an emergency at church.
If you are willing to participate, please see Ruth Kroneman. She will add your name to the appropriate list.
Trinity Lutheran Church 
If you don’t get enough folks you might consider contacting the American Red Cross in Madison. I’ll bet they offer First Responder training and cert for a reasonable fee. You could offer it to church members for a reasonable fee to cover costs. With the large population of elderly and families that Trinity has, you might have quite a few folks interested if the fee was reasonable.
