November 2025 Update
I provide tuning and repair service to all makes and conditions of pianos, and have a large purpose-built workshop fully equipped to provide every aspect of piano rebuilding except cabinet refinishing. My tuning practice includes recording studios, teaching studios, churches and schools, but mainly residential customers with all types and ages of pianos.
At this time I am only maintaining existing clients and taking new clients in the immediate Strathroy ON area, and these I am sharing with colleague and friend Koen Tholhuijsen. Please feel free to contact me about any piano-related matter, including advice on purchase or sale.
The following are technicians serving London and the wider area, all graduates of the Piano Technology Program at Western University (UWO), and are highly recommended. Click on their names to view their own website.
