Cello Technologies Seattle

Today is the 25th anniversary of Cello Technologies Seattle (and this summer is the 40th anniversary of Cello since it's founding!). 25 years under local ownership after the national corporation succombed to the pressures of the recession of 2000.
It has been quite a wild quarter-century for this industry, thankfully unmatched quality and customer service are still sought after attributes that Cello continues to provide.
As the northwest's oldest residential systems' design and integration firm, we hope that you continue to demand excellence from us for decades to come!
