What our Customers are saying about us

A Model Organization
Bryan Campbell and his entire team at DDB are truly a model organization. I cannot remember a single time DDB has not come through on quality and at service levels that are rare these days. Most recently I let Bryan know I had an order coming his way on Thursday, March 29 for three DDB cabinets, all of which required air conditioning units and cabinet insulation to be installed prior to shipment. I asked if he could get them assembled and picked up by our carrier by Friday, March 30. It typically takes five business days to do one integrated cabinet like these. Bryan and his team at DDB completed all three cabinet integrations in less than a day and made the pickup happen. I really cannot say enough about Bryan and his entire team at DDB.
