"For the past eighteen years, as Director of Music at Sacred Heart Catholic Church (Covina, CA) and Music Teacher at Sacred Heart School, I have called upon John Caterino to tune and maintain the pianos located in the church and school. John has always demonstrated excellent professional service in his work with these instruments, and he has consistently maintained first rate communication with me and with the administrative staff.
