"Jerry Raz has been tuning our 1891 Steinway annually since the late 1990s. He is punctual, thorough, and reasonably priced. His is also personable and very knowledgeable. He has made several repairs to this vintage piano over the years to keep the action functioning as it should. Under his care, our piano has always sounded great. I recommend him highly." .....Jim L., Berkeley
"Allegro Piano Service is an excellent piano tuning service, and it has been for the last thirteen years that Allegro has tuned our piano. Jerry is a very skilled and experienced piano tuner, who is also very funny and amazing to talk with. I recommend Allegro to anyone who desires a trusted, experienced, and outstanding piano tuning service." .....Peter C. & Annie K., San Pablo
"Jerry has been my excellent piano tuner for more years than I am willing to admit. He has not only tuned and voiced my Yamaha C5, he has done a warranty keyboard replacement, added a humidity control system and replaced the hammers, all with the same high quality workmanship. I would recommend his service to anyone."
