In 1998, he settled in Ottawa to teach high school music. There he joined the Piano Technicians Guild and began his studies to become a Registered Piano Technician. (Jan 2005) It is there that he founded Mr. Tuner Piano Service. After three years in Ottawa, he moved to Montreal where he taught music and tuned for three years before becoming a full time piano tuner. He now has three technicians who work with him to help tune his customers pianos.

In 2006 he founded the Mr. Tuner Piano Technicians school in order to train technicians for his business and also to continue his love of teaching. As of July 2007, the school has graduated 23 students from the basic tuning course. Two of those students are now tuners for Mr. Tuner Piano Service and many others successfully tune their own pianos.

The course is taught at Westend Pianos in Montreal West. Westend Pianos is a well respected piano rebuilding facility that is owned by Doug Yeats, who is also a Mechanical Engineer. The facility is recognized as the premier rebuilding facility in this region and farther. There are three floors in the building that are used to give students the opportunity to practice their tuning in isolated areas which aids in hearing the notes better.

Each of the 10 lessons is broken into two one hour slots. The first hour is a lecture and the second hour is for hands-on practice. Mark walks around and helps students by offering words of encouragement and advice, while being present to answer specific questions the students may have about their particular piano.
