Netzow's is Milwaukee's authorized Yamaha Piano dealer. Netzow's Pianos has a long and proud history in Milwaukee, and is Wisconsin's oldest and most experienced piano dealer. Established in 1885 by the pioneer of piano building in Milwaukee, Charles F. Netzow, the company began as a piano manufacturer, offering a full line of pianos, from uprights to baby grands. Several years later, we established ourselves in the piano retail business, seeking out the finest instruments, with an emphasis on highest quality and value.
