Graham Unsted Co-Owner, Assistant General Manager

Graham started piano lessons at age six but at age 12 decided to concentrate on guitar instead. At age 16, he dedicated himself to practicing an hour a day and began to advance much quicker in his abilities. Around the same time, he began focusing on learning metal songs, whereas previously he had been devoted to playing the blues. This broke his habit of playing the same style continually and broadened his perspective of different genres. Around that time, he also started writing his own progressions and riffs and recorded them onto his computer.

As a shy and introverted teenager, Graham never imagined that he'd be performing in front of other people. He soon decided to conquer his stage fright so he could share the music he was making with other people. Graham attended the Toronto Film School and completed his certificate in Recording Arts Technology. After graduating, he formed his first band. He soon lost his stage fright and became hooked on performing. Graham not only plays all the instruments we teach at School of Rock but can also sing. Graham is very passionate about teaching at School of Rock and enjoys sharing his passion for music and performance with all his students. He is very grateful and fortunate for the opportunity to advance the abilities of young musicians in such an incredible environment and hopes to advance himself as a musician in the process.

She has had the great fortune of working with incredible and renowned artists, composers and musicians through her endeavors.

Since starting singing before she could speak and taking piano lessons at the age of three, Raquel has never been able to turn down a stage (her favourite being the Toronto Centre for the Arts, where she has repeatedly performed as a soloist). She was an ensemble member and mass choir member with the Bach Children's Chorus and Bach Chamber Youth Choir. Raquel is currently exploring, testing and pushing her artistic and musical boundaries through pursuing her own music while studying Jazz at Humber College and is a firm believer that knowledge gained is only as useful as much as it is shared.

In high school he played in many different school ensembles, including concert, intermediate and symphonic band, as well as the string orchestra (playing violin) and their choir, The Mackenzie Singers. During the last two years of his high school career Jesse also began to form and play in rock bands in his local area.

After graduating from high school, Jesse enrolled in Humber College, where he graduated from not only their Theatre Production program but also their Jazz Performance program with Honours. During this time, Jesse began studying jazz percussion from instructors including John Adames, Steve Mancuso and Ben Ball.

John Loree Guitar Teacher, Bass Guitar Teacher, Piano Teacher, Singing Teacher

John began his musical journey with pop and classical music. He was taught how to sing at an early age by his classically trained mother, a former Elmer Iseler singer. After learning to play both the clarinet and trumpet in elementary school, he entered the high school band knowing he wanted to play a new instrument. He borrowed a friend’s guitar one day and quickly discovered that this was the instrument for him. He then quickly formed a high school punk band and began learning how to write songs and perform.

After graduating from Unionville High School’s Arts York Drama program, John threw himself into playing as a musician full-time and learned to play the drums, piano and bass. John worked as a production and live sound/lighting technician during this time, working for Pandor among others. While continuing to perform, John was accepted into, and graduated from, Seneca College’s IMP. This program gave him the skills he needed to record, mix and produce his own music. He continues to perform throughout the GTA and hosts open mics with his cover band, The Generations.

John brings his positivity and focus to each lesson, with the goal of bringing out the best in every student by making learning fun and focused. He is very excited to share his love for music with a new generation, drawing on his past experiences to help students hone stage presence, technical proficiency on their instrument, and, most of all, the confidence of a rockstar.

Michelle Ding Piano Teacher

Michelle has had a love for music ever since she was a baby. From what her mother recalls, she would sing lovely songs for her every morning even before she learned how to talk. Continuing her love of music, six-year-old Michelle begged her older cousin to teach her the simple things that she had learned. At eight years old, Michelle started taking official piano lessons from The Royal Conservatory of Music (RCM). After completing grade nine piano with RCM, Michelle took a break from lessons and now enjoys practicing on her own and playing the piano for fun.

Michelle came to know about School of Rock when she decided to start taking guitar lessons to further her knowledge with different instruments. She is continuing her guitar lessons while studying Early Childhood Education at Seneca College. Michelle strongly believes in play-based learning where children learn and have fun at the same time. Her personal philosophy is to encourage children and to observe children’s interests and plan interesting activities to further their developmental knowledge.
