We were honored by the repeat visit of Mr. Roger Breisch, and his insights on a very important subject of youth suicide.   He gave several examples of phone calls he received during his 3000 hours as a volunteer answering calls on the National Lifeline, and more than 11 years working with teens in an anti-drug, anti-alcohol program. For those between the ages of 15 and 24, suicide is the second leading cause of death.    He also works with Project Snowball, camps helping at-risk teens.
