Jimmy Hippenstiel – Artistic Director

Jimmy Hippenstiel – Artistic Director“When the students love what they are doing, it shows, and the MTA student does it better than anyone else! Their gift is an inspiration to all and that kind of inspiration needs a permanent place in our community.”

Jimmy currently serves as the resident Artistic Director for Musical Theatre Academy of Orange County. As Artistic Director, Jimmy’s responsibilities include producing, directing, and choreographing all the full-scale stage productions for both the younger and older kids enrolled at the Academy. Under his direction, the real mission of MTA is realized. The students not only learn the skills of singing, dancing, and acting, but they develop a mature focus and discipline that allows them to excel in all aspects of their adult life. Through the social interaction they have in developing lifelong friendships and performing in front of audiences, students gain the higher confidence levels and an ability to take on challenges without fear that are so important in reaching any goal they set for themselves.

Jimmy’s background has taken him around the world as an entertainer with a variety of well-known and respected organizations including Princess Cruises and the Walt Disney Company. He has performed at New York’s Lincoln Center, Radio City Music Hall, the Hollywood Bowl, Las Vegas, the St Moritz Music Festival, and many of the top resort hotels in Hawaii. Jimmy was a member of the world-renowned Citrus Singers and the Young Americans. He has been a featured lead in productions of many successful plays including “Hello, Dolly,” “West Side Story,” and “A Chorus Line.” Jimmy recently made a return to the stage himself, performing in one of his dream bucket list shows, 3D Theatricals critically-acclaimed production of “Ragtime.” The experience managed to rejuvenate Jimmy’s true inner love for the theater, and reminded him how important it is to always fuel his student’s passion for what they love and to provide them a safe forum at MTA to hone their skills and make new friends.

Jimmy received his Associate of Arts degree in Music and Conducting from the esteemed Citrus College and then went on to earn his Bachelor of Arts degree in Musical Theater from Cal State, Fullerton. Since his joining the MTA family in 2001, Jimmy has become very passionate about his work as on a daily basis he has the privilege of inspiring the performer within each student with results both onstage and offstage that are always amazing to see.
