Friendly, prompt and efficient describe Mark’s work at Calkhoven Piano Tuning. I’ve lost track of how many years Mark has tuned my piano. Over 15 years, I think. My whole family calls on Mark to tune their pianos. No complaints, whatsoever. He’ll drive anywhere in the city as well as the surrounding area(e.g., Okotoks, High River, Strathmore). A few years ago, Mark added piano repairs and refurbishing to his services. He came over quickly when I busted one of my strings when practicing a tricky part a little too viciously. Seriously though, he can handle a complete piano refurbishing, not just broken strings. If you need a height-adjustable piano footstool, Mark’s your man. Well-crafted and much more affordable than what you’d get at some music retailers. If you’re looking to buy a used piano, you can call Mark to inspect it(you know, like getting a mechanic to look over a used car). Mark is a Registered Piano Tuner and has served on the Board for the Piano Technicians’ Guild.
