Brandon Hadlock

Center Manager
Some of my favorite math classes I have taken are Calculus 1 (Fall 2021) and Ordinary Differential Equations (Spring 2024). Some things I enjoy doing include competing and performing dance as well as bowl on a frequent basis. In high school I was the first ever male dance sterling scholar for Stansbury High School and went on to compete at the state level. I have done ballroom for about 7 years and I am currently the dance captain for the Utah Tech Ballroom team. Bowling is one of my biggest hobbies. I also collect decks of cards.

Fun Fact: When I tell people I am a frequent bowler the most common question I get is "What's your highest score?" I used to only be able to say I have gotten 3 - 267's, but now I have gotten a 279 which was 9 strikes in a row before missing one pin and sparing/striking again.

Favorite Number: 17 is my favorite number. It is such an interesting prime number that honestly is different than any other number we use in math.

Education: I will be graduating in Spring 2025 with my Bachelor of Science in Secondary Mathematics Teacher Education. This will be an add-on to my Honors Associates of Science I received in Spring 2023.

Why I love Mathnasium: I enjoy working at Mathnasium because you can really tell when the students start to get what they didn't understand before. Students have that ah-ha moment and it is truly amazing to see them start to enjoy something they didn't even like to look at before.

Fun Fact: In 7th grade, I got second place in the state competitive math test. The guy that got first place was a classmate and friend of mine. We got our names in the local paper.

Favorite Number: Pi

Education: I went to Pineview High School and Dixie State University.

Why I love Mathnasium: Once you get the hang of it, math is beautiful, exciting, even creative and artistic. I want more people to grow up knowing that delight.
