Mary Grace del Rosario was born in the Philippines. She started violin lessons at age 10 and shortly after she was featured as a soloist playing Mendelssohn’s Violin Concerto in D Minor. Under the tutelage of Arturo Molina, one of the Philippines' finest violin instructors, she flourished and won national competitions and participated in international youth orchestras. In 1993, she was concertmaster of the ASEAN (Association of South East Asian Nations) Youth Orchestra, then performed with the Jeunesses Musicales World Orchestra. In 2001, she was chosen to be Manila Symphony Orchestra’s Concertmaster, a post she held until she moved to Canada in 2008.
After graduating with her Bachelor of Music in the Philippines in 1998, Mary Grace started teaching violin at St. Scholastica’s College of Music, house of the finest strings program in the Philippines. During that time she also became the school’s Junior Orchestra Instructor and Conductor.
In 2007, Mary Grace married a fellow Filipino violinist who was based in Coquitlam, BC. Upon arriving in Coquitlam, she took some time adjusting to her new home and playing various musical engagements around town as part of a string group called Rosario Strings. She and her husband joined the Vancouver Philharmonic Orchestra in 2008 where Conductor Jack Zhang was also Musical Director. In 2009, Mary Grace won the position of Concertmaster with the New Westminster Symphony Orchestra.
Mary Grace had her first baby in August of 2009. Her husband and little girl serve as the sources of her inspiration.
