February Alumni Spotlight

Mark St. George

Rosary Class of 2002

"My time at Rosary (Trinity) was very enjoyable, having received a great education and having formed friendships that have lasted long past my time in the classroom. The A/V Media Club was established during my time at Rosary and I was an early host of the closed-circuit announcement program. My all time favor-

ite teacher is still Mrs. Linda Anthony, who was my French teacher.  I always looked forward to her courses because of the amazing bond she had with her students and for her constant encouragement, even when I struggled. I cannot say enough how Trinity has influenced my life and helped me become the person I am today!"

Understanding through the African American – Jewish Experience

During a year-long, educational leadership program, students become social justice activists and change agents, learning through the lens of the African American and Jewish experience. Students meet over the course of a year – 460 hours in all, which includes three weekend retreats, monthly meetings, and a three week summer transformational journey covering much of the east coast and the “deep south.” Cultural Leadership opens students’ eyes to problems that often go unnoticed in our communities, such a racism, anti-Semitism, poverty and oppression. If you are currently a freshman or sophomore (or junior) and would like more information about Cultural Leadership, or an application visit their website ( or contact the office at 314-725-3222. The deadline for accepting applications has been extended until April 23.

Model Of Justice Award
  The Martin Luther King, Jr. Model of Justice Award is an annual award presented to high school students who have demonstrated, through their attitude and work, a commitment to service humanity in the broader community. These students have made social justice a central part of their life and have committed themselves “to the noble struggle for equal rights.”
  This year two Trinity students have received this award. Junior Andre Bernaugh was nominated through his parish, Our Lady of Guadalupe and junior Cayla Thurman was nominated through Trinity Catholic High School. Both Andre and Cayla will be honored as a part of the 38th Annual Archdiocesan Mass and Commemoration at the Cathedral Basilica on January 19th.
Congratulations to Andre and Cayla!

Trinity Clothing Box

As your family prepares for winter and you are cleaning out closets and drawers, don't forget about the Clothing Box on the lower parking lot at Trinity. If you are discarding old shoes or clothes don't just throw them away. Bring them to Trinity and put them in the Clothing Box. Trinity receives funds for the amount of clothing collected from the box. It's a great way to recycle your clothing and help Trinity at the same time.
