Get to Know Principal Jenn Sinclair

Posted on October 21, 2025

October is National Principals Month! To celebrate, we’re sharing short Q&As with each of our principals—giving you a glimpse into their leadership style, favorite parts of school life, and what drives their #PHMExcellence every day.

If you could swap places with a student for one day, what class or activity would you be most excited to participate in — and why?

Art – I am always amazed by the skills and techniques students learn during their time in art!

What’s your go-to morning routine (or must-have snack/coffee order) that helps you tackle the day?

Always coffee and usually a podcast on the way to school.

What were you like as a middle or high school student — and what’s one piece of advice you’d give your younger self?

I was very shy and quiet, except with my friends. Advice I would give to my younger self is that the people you surround yourself with are very important — so choose wisely!

What was your favorite school lunch or snack when you were a student? What is your favorite school lunch now as a principal?

I think everyone loved the rectangular pizza — it’s still great to this day!

What’s one fun fact about you that most students or staff don’t know?

I grew up on a farm in Southern Indiana

Do you have any hidden talents or hobbies outside of school that might surprise people?

I have an 18 month old, so that takes up most of my time, but I love to play board games, hiking, and traveling!

What’s one thing on your bucket list you still hope to do one day?

Hike to Machu Picchu, visit all 7 continents

What’s your favorite school tradition or event?
