MISSION — It was a packed house at Mario's Convention Center as more than three hundred nurses from the Valley school districts gathered for the Region One School Nurse Educational Conference in Mission. McAllen I.S.D. Health Services representative Adaila Del Bosque spoke about the conference, "One of the vital things that we enjoy about this conference is the updates that we need to be aware of in order for us to do a better job as a school nurse. So one of the topics that is enlightening to us is suicide prevention."
