{'quote': 'I would highly recommend Mr. Chung’s piano services! He is very professional, communicative, easy to work with, experienced, and knowledgeable. He’s a great piano tuner, but also did a phenomenal job overseeing the refurbishment of my 1919 Chickering Bros. upright piano, and the result is amazing!', 'author': 'Jessica Miller'}
