Principal’s Message

Welcome to the online home of Trinity High School and thank you for your interest in the Shamrocks. Our academic, athletic and fine arts programs have earned great recognition; faith formation resides at the core of our mission for our students and staff.

Trinity Shamrock students are problem solvers. They learn to analyze, evaluate and respond to what they read, hear or see. Taking control of their own destiny while being open to growth and intellectual development, while having a commitment to serving others.

Our graduates have a record of success during their collegiate years and match that success in their professional lives. Trinity is proud of our Shamrocks past and present and we look forward to meeting our newest members of our family very soon.

Whether you are a prospective student, a graduate, a parent, or someone interested in learning more about Trinity, I thank you for visiting our website. I invite you to visit us in person and to see all that Trinity has to offer.

Pax et bonum,
Mr. Joseph E. Gressock

Annual Appeal

The Annual Appeal plays a primary role in enabling the school to realize the progressive education that distinguishes Trinity and, in the spirit of our mission and motto, encourages students to strive for “the highest good.” Through the generosity of our benefactors, we have been able to change the lives of our young adults through offerings of financial aid support, classroom and technology upgrades, campus ministry programs, and athletic and fine arts programs. Unrestricted gifts to the Annual Appeal are particularly valuable as they permit the school to allocate resources where they are needed most during the school year. Please help us to continue providing an outstanding experience for our students and for keeping the Trinity tradition of all-round excellence. We look forward to seeing you at one of our upcoming events.

The Capital Campaign

What a wonderful and exciting time it is for all of us to be part of the ministry of Trinity High School! We have embarked on a new and adventurous chapter in our school’s history, which will equip us for years of service and witness in the name of our Lord Jesus Christ. As part of Trinity’s strategic plan for the future, the Trinity High School Board of Directors has initiated a Capital Campaign. Our plan for continued educational quality includes renovations and building our endowment. A $13 million Capital Campaign addresses these needs. It is our current plan to conduct three 3-year Capital Campaigns (a total of 9 years) at approximately $4 million each. Our board, administration, and faculty are all committed to the long-term success at Trinity High School, as well as our Bishop and, in turn, the Diocese of Harrisburg. We need you, as our community of faith, to join with us for a successful capital appeal.

In Memoriam of Bishop Joseph McFadden (May 22, 1947-May 2, 2013)
Bishop McFadden was a strong proponent for Catholic Education and approved the Capital Campaign at Trinity High School. He provided this quote shortly before his passing:
“There is no more important mission in the Church today than the Catholic education of our youth. I wholeheartedly endorse the Capital Campaign of Trinity High School which will position this outstanding school to serve the educational needs of our young men and women for years to come.” – Bishop Joseph McFadden

Each day, approximately 50 children are diagnosed with cancer in the United States. In fact, there are almost 40,000 children undergoing treatment for this disease at any given time. Unfortunately, due to lack of funding for research programs, effective treatments for many types of cancer remain elusive.

For the seventh consecutive year, Trinity High School will participate in a fundraising and awareness campaign in an effort to change this outcome for these children and their families. This student-led, year long effort will culminate in March with a 12-hour, no-sitting, no-sleeping dance marathon where more then 400 student volunteers will demonstrate their support by taking a stand against cancer.

We need your help! We have become passionate about this project and would greatly appreciate it if you would join us in the fight against pediatric cancer by making a gift to THON.

Your donation to THON enables the Four Diamonds Fund to provide outstanding care and comprehensive support to children undergoing treatment. Additionally, with the help of THON, Penn State Children Hershey Children’s Hospital is able to lead initiatives for innovative and collaborative cancer research. Because of these efforts, Penn State Hershey continues to be recognized by U.S. News and World Report as one of the best children’s hospitals in the nation for pediatric cancer care and research. Please check out our DonorDrive link if you are interested in donating.
