Holy Trinity staff and our Titan ambassadors hit the road this week, dropping in on middle schoolers at both Holy Name of Mary and St. William the Abbot.

There is nothing quite like watching our high schoolers reconnect with their grammar school roots—sharing real stories about life at Trinity, the friendships they’ve made, and all the paths open to them at 98 Cherry Lane as a member of the Class of 2031.

If your family is currently navigating the high school search, we’d love to show you what makes Holy Trinity so special. Registration is now open for our Open House on Saturday, October 17th (10:00 AM – 1:00 PM) as well as our fall Buddy Days!

Visit our Linktree in our bio to register and come see the Titan family in action. 💚

Our Girls' Soccer team fought to a tough 1-1 tie against St. Savior on Wednesday, putting on a great display of grit from start to finish.

Huge shoutout to the crowd in the stands, too! Our Titan fans showed up in full force, bringing incredible energy and keeping the momentum high for our ladies all afternoon. Love seeing that Holy Trinity school spirit out in full swing!

Mrs. Becker's Anatomy & Physiology students put their technical skills to the test today! Our Titans applied their anatomical terms in the lab—following directions to make cuts across different planes, then drawing and describing their work step-by-step. Great focus today, topped off with a well-earned reward at the end!.

Gathering as a school family for Mass is always special, but yesterday’s reflection gave us all something meaningful to carry with us into the rest of the week.

During his homily, Fr. Francis offered our students such a poignant reminder: God calls each of us to step into our true, authentic selves. In a world dominated by social media—where it’s so easy to compare our everyday lives to everyone else’s polished highlight reels—he reminded us that our real worth isn't found in a post or a filter, but in who God created us to be.

And as always, our choir sounded absolutely incredible filling the auditorium with their joyful voices. 💚

While our cross country team was out putting in the miles and our baseball team was getting reps on the field, the weight room was packed for after-school conditioning with our Strength & Conditioning Coach, Mr. Galluzzo. Even Principal Mr. Colomban jumped right in to join the workout and sweat it out alongside our student-athletes!

Workouts with Coach Galluzzo run every Monday and Wednesday afternoon, building the strength, endurance, and culture that drive our Titan programs forward. Love catching our Titans—and our leadership—putting in the work!

Mr. Colomban, Mr. Jones, and several Titan ambassadors spent yesterday afternoon with students at St. Joseph School in Garden City to talk about life at Holy Trinity. It’s always incredible when our students get to return to their middle school roots, sharing their experiences with the Titan spirit, all the opportunities at their fingertips, and what makes 98 Cherry Lane feel like home.

For all prospective families starting their high school search, we’d love to welcome you next! Registration is officially open for our Open House on Saturday, October 17th (10:00 AM – 1:00 PM) as well as our fall Buddy Days.

Our Lady Titans battled with relentless heart and energy on the pitch yesterday against Montfort Academy! The toughness and unity this group shows every time they step out on the field make us proud to be Titans.

Shoutout to our HT Broadcast crew as well, who rolled their gear down to the press box to bring live commentary to everyone cheering from home. Keep pushing, Titans! 💚

Mrs. Martin’s seniors were hard at work in the writing lab during College Composition & Rhetoric, diving deep into the writing process. From brainstorming and outlining to drafting and refining their ideas, the focus in the room was incredible as these Titans hone their craft and prepare for college-level expectations.

It’s always impressive watching our future graduates put in the work behind the scenes to make their voices heard! ✍️📚💚

Gathering together as a school community is at the heart of everything we do at Holy Trinity.

We invite all of our Titan families to join us this Sunday, September 27th, for our Holy Trinity Family Mass! Mass will begin at 10:00 AM, celebrated by Fr. Francis. Following Mass, please stick around and head down to the cafeteria for a light brunch and some great fellowship with fellow Titan families.

It’s always a wonderful morning to catch up, slow down, and share in faith together. Bring the whole family—we can’t wait to see you there! 💚
