Producer and multi-instrumentalist, Nathan Glaser grew up making electronic music and playing jazz trumpet and piano. Like many kids, he took piano lessons for a year, then stopped and went back to it on his own terms as a teenager when he wanted to start recording. Therefore, his goal as a teacher is to try to support his student’s interests as much as possible, and adapt lessons to fit what they enjoy about music.

Nathan graduated from Lawrence University in Appleton, Wisconsin with a Bachelor’s in Jazz Composition in 2021. Shortly after, he began work as a composer’s assistant to Francis Ralls, and since then has made music for MasterChef, The Voice, and Extreme Music, as well as worked on arrangements for Disney Parks. Beginning in 2024 he has been the music director for the contemporary service at Christ Church Episcopal. Nathan plays in multiple local groups such as the band Organbreath, a Booker T. & the M.G.'s inspired band that also includes bART faculty member Tye Slagle. When he’s not making music, Nathan can be found climbing at Climb Tulsa and playing chess.

Ms. Hazelton is a member of Music Teachers National Association, as well as the Oklahoma and Tulsa local chapters.

Soprano and actor, Coral Kestler has a passion for empowering others to pursue what they love. She made her Houston debut with Main Street Theater as Nancy in Fancy Nancy the Musical in the summer of 2024. She has also performed in other vocal roles such as Cinderella in Into the Woods, Margaret Leavitt in Silent Sky, and ensemble roles in Secret Garden and The Sound of Music. Additionally, she has played many roles in film and straight plays, including Cecily in The Importance of Being Earnest, Kathryn Schaub in Radium Girls, Cookie in Rumors, and Third Woman in Clark Conservatory’s Tate Award-winning production of Secret in the Wings. Coral loves to engage with her Tulsa community in several ways, including music directing Riverfield Country Day School’s production of Mean Girls, performing with the First Methodist Cathedral Choir, and working as a party princess with Once Upon a Crown for three years. Coral holds a Bachelor of Fine Arts in Musical Theatre from Oral Roberts University.

In the year 2020, Coral started working at Clark Youth Theatre, where she taught students voice, acting, and improv. During her time there, she received trauma-informed classroom strategies through the Opportunity Project to meet students where they are.

Coral began growing her musical roots in cello. Beginning at the age of four, she played cello for seven years, and attended The bART Center for Music’s Conservatory program for three years. This helped give her the foundational musical skills she needed in order to pursue singing later in her life.

Although she took classes at a young age, she truly began to discover her love for musical theatre in high school when she started performing in choir and in musicals. She challenged herself to grow by attending different competitions including the International Thespian Festival where she received a Superior Rating in the Musical Theatre Category 2019. This continued in her college years where she received a grant from the 2022 Crescendo Music Awards.

Coral cares deeply about helping every student, young and old, understand the science of singing. In lessons, students can expect to learn the physiological process of singing, as well as build lasting practice habits. They will also learn how to deliver an engaging performance through acting techniques.

Outside of theatre and music, Coral enjoys writing, art, and spending time with her friends and family (bonus if coffee and/or cats are involved)!
