HOMETOWN: North Richland Hills TX

INSTRUMENT (S) PLAYED: Sax HOBBIES OUTSIDE OF BAND: I like to ride my Harley and I’m a part-time firefighter for the city of Rockwall PETS: two dogs lab golden mix and two cats

WHAT INSPIRED YOU TO BE A MUSIC TEACHER: having Dyslexia made school pretty tough for me. HS band was the one thing that I was able to work hard at and be good at something, not just working hard to keep up. It was also just a lot of fun, and I wanted to be able to give that experience back to others. To provide a place that everyone felt valued and needed.

SOMETHING FUN ABOUT YOU THAT WE WOULD ENJOY KNOWING: I played on the bass line for my high school drum line and marched trombone one year in college

WHAT’S YOUR FAVORITE HIGH SCHOOL MEMORY: We had a football game in Grand Prairie that snowed during the game to the point that the field was slick due to the ice that was one it. Let’s just say that halftime and how we acted in the stands was a little different that night!

WHAT’S YOUR FAVORITE COLLEGE MEMORY: going on tour with David Maslanka, and working summer music camps especially the year that I worked with Jeff Richardson who is now the head coach at Utley MS

Hobbies outside of band: composing and arranging music

Pets: my fiancee has the cutest dog in the world, so I’ll soon be his step-daddy. His name is Grizzly, but I call him Mister Grizzly

What inspired me to be a music teacher: Above all else, I was inspired to be a music teacher because I love seeing progress, being part of people learning new things, going through challenges and coming out on the other side a stronger person with unforgettable memories is what I love the most.

Something fun people would enjoy knowing: when I was in elementary school, I wanted to grow my hair out so I would look like I was in a rock band. My mom’s compromise was to let me grow a mullet. So I definitely rocked a mullet through much of my younger years.

My favorite high school memory: I loved all the bus rides to away football games, band performances/contests and band trips. The many years of games, contests, and trips are all blended together in my memory, but I loved being with my friends in band, hanging out, telling jokes and growing close together.

My favorite college memory: my favorite college memory was writing my first original composition. I was very self-conscious and definitely didn’t feel like I was good enough to write my own music, but I had friends, family and teachers who encouraged me to give it a shot. That first piece, called “Song for Monica”, was eventually published and since then, it’s been added to the prescribed music list for solo and ensemble and performed by some of the RHHS percussionists. It still feels unbelievable My favorite part: now my students at RHHS are starting to write their own music, too.
