In 2012, Margaret Maria was awarded the Leading Women Building Communities Award by the Government of Ontario for her work in the Ottawa community with OrKidstra (an El Sistema inspired program) she co-founded in 2007 along with two of her musical colleagues, Tina Fedeski and Gary McMillen. OrKidstra is a thriving charity that brings musical opportunities to children who would otherwise be unable to participate. Margaret Maria is also an Honorary Board Member and the conductor of OrKidstra. You can find her sharing her love of music with the kids every other Wednesday and Thursday at the Vanier Hub and Bronson Centre in Ottawa. Her passion for social justice and music continues to hold strong and true even though she is focused on composing and creating music. In 2012, Margaret and Tina were recognized as Kickass Canadians (www.kickasscanadians.ca).

Margaret Maria is very passionate about teaching and has given master classes in Canada, the United States, and Mexico. She has taught at the University of Ottawa, Carleton University, the National Arts Centre’s Summer Music Institute, the Southern Ontario Suzuki Institute and currently teaches at the National Capital Suzuki School of Music and OrKidstra.

In 2011, Margaret Maria decided to leave her professional post as cellist with the National Arts Centre Orchestra of Canada to follow her dream of composing and producing her own music. Working in the contemporary Post Classical, Electro Acoustic, New Age, Instrumental, Cinematic, and Steampunk genres, Margaret Maria creates stunning new music with her phenomenal cello playing at the heart of it. Her two children’s albums, A Cello for Chelsea (2005) and Zara the Maggini (2006) were her first creative musical stories that incorporate her narration, musical compositions, and arrangements, into delightful performances that sparks the imagination of children and adults alike.
Seamlessly drifting between genres and going where her spirit takes her, you will find a variety of music – some expected and some unexpected. Venturing into her creativity is a shapeshifting activity in itself. Opening up to her sonic world and exploring all its dimensions is the fascination. Initially a cellist with a traditional classical performance past, she has broken out of every mould to create something unique and always from the heart. As a graduate of the Curtis institute of Music and a professional cellist with the Vancouver Symphony Orchestra and the National Arts Centre Orchestra, she soaked up the music of the past to enable her to create music of the future.
Her 14’th album, ‘Between Worlds’ with the great Canadian soprano Donna Brown was released in June 2022 on the Canadian Music Centre’s Centrediscs/Naxos Label. Margaret Maria is currently working on a commission for Strings of St. John in Ottawa to premiere on Women’s Day 2023, her Goddess of Edges most recent series of compositions, her newly formed spontaneous improvising duo Marbyllia and a creativity retreat online course culminating in Italy at BIIMA July 2023.

Teaching ArtistBryan Parker

Bryan decided that he wanted to play a brass instrument – the Euphonium – in Grade 8 at Philemon Wright High School, shortly after his first music teacher had demonstrated all of the band instruments. Over the next few years, Bryan learned to play the trombone at the suggestion of his second music teacher in order to play in the school’s jazz band, which gradually led to the bass trombone. Bryan recognizes and greatly appreciates the early influence of both of his high school music teachers.

Bryan’s formative musical experiences were playing the bass trombone in the Heritage College Big Band and the Ottawa Youth Orchestra. The latter gave Bryan his first taste of orchestral playing – Mars, from Gustav Holst’s The Planets – and orchestral music continues to be a major source of musical fulfilment. Bryan learned much under the baton of John Gomez, and looks back on those years with fondness and gratitude.

Bryan later obtained a Bachelor of Music degree from the University of Ottawa, where he studied under Douglas Burden (bass trombonist, National Arts Centre Orchestra). He also played in the University Orchestra (David Currie) and sang in the Choral Ensemble (Lawrence Ewashko). Bryan’s approach to teaching music is strongly influenced by his experience working with these three musicians and pedagogues.

Bryan joined the Ottawa Youth Orchestra Academy (OYOA) faculty for the 2004/2005 season as director of the Junior Brass Ensemble, to which an Intermediate Brass Ensemble was added in the 2016/2017 season. Having marked his fifteenth year with the OYOA in 2019/2020, Bryan continues to feel that working with young brass students is one of his favourite musical activities.

Since the fall of 2018, it has been Bryan’s great pleasure to be an OrKidstra Teaching Artist. OrKidstra’s mission to empower kids from equity-deserving communities by teaching life skills (e.g. teamwork, commitment, respect and pride in achievement) through the universal language of music resonates strongly with Bryan, and he is grateful to have the opportunity to be a part of this truly inspiring organization and work with some wonderful young people. The experience continues to expand Bryan’s horizons as a music teacher.

For many years, Bryan has been an active member of the local music scene. He has been the bass trombonist of the Ottawa Chamber Orchestra since 2005, and held the same chair in the Divertimento Orchestra from 2013 to 2018. He has been a church musician, notably at St. Brigid’s and St. John the Evangelist, and has on many occasions played as a freelance trombonist in the community.

An avid chorister, Bryan has sung with the Ottawa Festival Chorus, the Ottawa Choral Society and is currently a member of the Ewashko Singers. Over the years, he has participated in many interesting concerts at the National Arts Centre and elsewhere in the community. Highlights include Bach’s B Minor Mass (Rilling), Beethoven’s Missa Solemnis (Zuckerman), Mahler’s Eighth Symphony (Nezet-Séguin), Britten’s War Requiem (Shelley), and La Machine (at LeBreton Flats with a giant mechanical spider and fire-breathing dragon!)

Teaching ArtistLucas Olsen-Willford

Lucas Olsen-Willford is a violinist born and raised in Kamloops, British Columbia. He began his musical journey at age 7 through an organization similar to OrKidstra. This upbringing ignited a passion for a life of music. Lucas was an Assistant-Faculty member at the Kamloops Interior Summer School of Music (KISSM) and spent many summers teaching all levels of Trombone, Ukulele and World Music to children of all ages. His can-do attitude once led him to become a percussionist for KISSM’s performances of Mama Mia!, one of his favourite musicals. During his time at KISSM, he was also able to work closely with the School District 73 strings program, mentoring youth, changing many broken strings, and leading string instrument workshops. Lucas has served on the Board of Directors for the Kamloops Festival of the Performing Arts and the Thompson Valley Orchestra. He has also been able to work with several orchestras across Canada, including the Kamloops Symphony Orchestra, the Okanagan Symphony Orchestra, and the Orchestre de la Francophonie. Lucas’ love for all genres of music has allowed him to work with people of all backgrounds and ages in various ensembles. He is currently pursuing a Bachelor of Music specializing in performance at the University of Ottawa. Lucas is extremely excited to get to know everyone in the OrKidstra family and help them succeed in every way possible!

During her university years her theatre career shifted towards production management with companies such as Black Sheep Theatre, Odyssey Theatre, TACTICS, and a Company of Fools.

Musically speaking, Christine has been teaching voice and piano, and running music and drama camps for many years. Notable performances from her university days include the soprano solo in Scriabin’s Symphony no. 1, Miss Jessel in Turn of the Screw, Fiordiligi in Cosi fan tutte, Ms. Pinkerton in The Old Maid and the Thief, Marcellina in le nozze di Figaro, and chorus in Don Giovanni and Die Zauberflöte.
