Shannon Jabczynski-Allen General Manager
Shannon Jabczynski-Allen was born into a rock n' roll family. Both of her parents were in a band together, Mid City Rock, where her mom was the lead singer and her dad was the lead guitarist. Needless to say, rock n' roll is in her blood. At a young age she developed her love for Aerosmith and Heart, which are still two of her favorite bands.
A born entertainer, Shannon discovered her passion for dance when she was just a tot. Although her parents would've loved for her to pick up an instrument, they realized that dancing was her way of expression and let her pursue it. She attempted to learn guitar but it just did not compute in her brain so she stuck with movement though never walked away from rock n' roll.
When she was 16 years old, she got her first job in sales. This was something that came very easy to her and in a few years Shannon stepped into a management role. After 15 years with that company, they decided to sell the business and Shannon came to School of Rock. She is now the General Manager at School of Rock Rockwall.
Richie Rodriguez Music Director, Guitar Teacher, Bass Guitar Teacher
Richie began playing guitar at age 8 and fell in love with music. At first, he was plucking his way through 90s rock songs that came on the radio and tapes that his parents had. Before he knew it, he was able to play along with more difficult songs and became inspired by classic Rock groups like Led Zeppelin.
Guitar continued to be Richie’s first love, but since there was no place for him to play with others at that time, he joined the school orchestra in 6th grade and learned to play violin. Richie continued to play violin in school until 11th grade when he decided to try and pursue other musical interests, such as drum-line and Jazz band. He then started a Rock band with some classmates before the group eventually went their separate ways after graduation.
Richie began working for School of Rock in 2017 as a substitute instructor for the Dallas and Plano schools. He continued to work at School of Rock for over four years as the Assistant Music Director, until making the move to Rockwall as Music Director. School of Rock is the most fulfilling and fun job that he has ever had since day one, and you won’t find anyone who believes in it more!

Glenn Austin Drum Teacher
Glenn started playing drums when he was nine years old after seeing a performance at his elementary school talent show. A student played a blue drum set along to a KISS song and he was hooked. Glenn played on everything that he could get tone out of with a pair of sticks his dad made for him out of wooden dowels.
After a few years of books, pots and pans, Glenn got his first real drums at the age of 14. He started playing along to every song on the radio, learning all he could about every style of music he listened to. After playing house parties with different garage bands he and his friends put together, Glenn got a call from a real working band in the club scene. They spent the next couple of years playing every club and venue in north Texas and southern Oklahoma that would let them play. Eventually that led to Glenn’s first tour with a “road” band.
After touring the Midwest for a while he got an audition with Vince Vance and the Valiants. They toured most of the southeastern U.S. After leaving the Valiants, Glenn freelanced with many artists, including two-time Grammy nominee and CMA Female Vocalist of the Year Janie Fricke, finally getting a gig with former Head East lead guitarist and solo recording artist Ricky Lynn Gregg. Glenn is currently the touring drummer for Texas recording artist Tom McKelvain and the Dirty Pesos.
