Welcome to the 2014-2015 academic year at Bishop McGann-Mercy Diocesan High School.  

Throughout the year your child will be challenged to “Serve the Lord with Gladness” by excelling in education and living the works of Mercy.

I look forward to sharing a wonderful year with you and your child filled with the spirit of the Mercy.


Carl A. Semmler, Principal
