I am so proud of the students achievements and continued success after HTHS. Their academic and life achievements is a testament of the dedicated work of the administration, faculty and staff at HTHS. In this day of so much uncertainty and instability in education, HTHS is here to provide a quality college preparatory education for its students. Keep up the great work!

I love being a student here, it is very divers. I have not only made many friends, I've felt like I belong. The staff is very friendly and the teachers help us with anything we need.

Holy Trinity gives a good selection course of activity pleasures. They offer Theater (which I am interested in),AV club which controls the sound booth, and poetry club,etc etc.. Holy Trinity is the best choice I've made and I bet it'll be the best that you would ever make.

Here at Holy Trinity we are able to be ourselves and the teachers are very helpful, they stay as late as possible and even support the students at sporting events.

Holy Trinity was most definitely the best choice for my son to attend. He`s currently a sophomore and I`m so grateful for this school. My son plays in the soccer team, has some honors classes, plays the trumpet in advanced Band and Is taking Spanish class this year. I think the small class sizes really do help. Staff is nice and pleasant to talk to. The best part is that I feel we (my son and I) both feel like this school is one huge family.

Going to Holy Trinity was one of the best decisions I have ever made. It was not my first choice, but as an upcoming junior, I am very happy I decided to go to such an amazing school.The teachers here are always there for you whenever you need them whether it be before or after school. I am pushed out of my comfort zone in order to not only succeed but to exceed my personal goals. Being in their honors B-STEM program I am presented with so many great opportunities I never imagined I could receive. They have a wonderful variety of clubs and sports that they motivate their students to join. At the end of every year, they hold an assembly for the students in order to recognize all their accomplishments in academics and sports. This really makes us feel valued and motivated to do even better. We are a family! We are HT!

As a student, Holy Trinity has given me many opportunities and now as an alumni, I am giving back by interning with the director of marketing and receiving experiences in the field I am currently studying at my University.

I have a rising Senior and Sophmore at HT. I love the small class sizes, extracurricular activities, and challenging courses. Last but not least, the amazing staff. Private education was something I always wanted for my children, but didn't think I could afford it. Holy Trinity has many opportunities for every family from different financial backgrounds which leaves no kid behind when it comes to private education. So if you are thinking twice due to the financial aspect, it doesn't hurt to give it a try. They partner with many great organizations who provide scholarships for students who qualify as well.

Holy Trinity is a small, but growing, high school full of character. The teachers and staff stay past 6 on most days and are more devoted than any teachers I've ever met. This school does not fail when it comes to growing your child's education and their heart. HT is the place to be!

As a rising senior, I can say that Holy Trinity has prepared me for the best. Holy Trinity is challenging when it comes to academics but thankfully we have resources around the school. We have teachers that stay longer after school to help their students or when a teacher isn't available we have a Resource Learning center with tutors and full access to computers.

Holy Trinity High School is a unique school. The small setting makes it easy to get to know teachers and make new friends. It provides a comfortable space for students to bloom and become the best versions of themselves.
