Mr. John Cullen's Home Page

Welcome to my home page! I am John Cullen, Teacher of Mathematics.

If you are looking for my colleague Scott Cullen (Teacher of History), please visit his page here: OMC (Other Mr. Cullen!).

This is my 19th year teaching at Hackettstown High School. My class schedule for the 2026–27 Academic Year is detailed in the table below:

Extra Help & Availability

I am available for extra help every day school is in session:

Before School: Room B-11 every morning before classes start.
Flex / Unit Lunch:
- Monday – Wednesday: Room B-11 during the first 20 minutes of lunch.
- Thursday – Friday: Available during the last part of lunch (department meetings and lunch duty occupy the first 20 minutes).

If you are confused, have questions, or need support, please stop by!

Please Note: Because I often have conflicting commitments during flex lunch, please let me know in advance if you plan to drop by so I can ensure I am in the room to assist you.
