“I cannot recommend the technical work of Mike Riffle strongly enough. In my decade and a half in the piano industry I have never met a technician who so seamlessly combines his vast knowledge, impressive skill, and willingness to seek help from others on the rare occasions when he does not know the answer. Mike has the rare ability to listen to the customer, and truly understand what they are saying, and what they need from their piano. Whether that be a retail customer, a school or university, or a performing artist Mike is always able to find a way to get exactly what they need for them.” … “I would happily trust Mike with any piano, and any customer whether institutional or retail. His work for us here has been exemplary.”

“I hosted and directed the American Lizst Society Festival in the bicentennial year Lizst’s birth. Registration for the event set a record for the society … 283 registrants came from Europe, South America, Asia, Canada and 33 of the United States, including recording artists, faculty and students from 66 institutions … concerts and lectures ran from morning to night. At the start of the last afternoon of sessions, I introduced Mr. Riffle as the technician for the pianos used during all Festival events. He received a tumultuous ovation from an audience overwhelmingly composed of professional pianists.”

Lizst Society, Contributing Editor Clavier Companion
“Our artist was very demanding in what she wanted the piano to do and what she did not want it to do and worked closely with Mike in getting the piano just right. In the end, she was extremely pleased with the result and all the other Steinway Artists present mentioned that the piano was obviously immaculately prepared and that they loved the sound that our new Steinway Artist Created with it.”

- Ike M. Van Meter Director, Institutional Sales, Steinway Piano Galleries
“Mr. Riffle has been the technician for the University of South Florida (All Steinway School) where I am the chair of the piano faculty. His work tuning, voicing and regulating has always been outstanding. USF School of Music owns a variety pianos (Yamaha, Boston, Kawai)Mr. Riffle’s work is equally satisfying regardless of the instrument. His professionalism is appreciated by all.”
