Countywide has consistently been Swinerton’s highest performing partner on the DCGS Operations Facility at Beale Air Force Base. Your office and field teams continue to excel in overcoming the unique administrative, security, and field challenges associated with this mission critical data center and intelligence operations facility.
- Jeff Good, Project Manager at Swinerton Builders
Countywide Mechanical’s project team held an integral role in delivering a quality East Tower Renovation project for the Grossmont Healthcare District. The project involved many unforeseen conditions, which prompted above and beyond efforts from Countywide’s people in regards to design assistance, procurement, coordination, and installation. Countywide’s people were always very professional, knowledgeable, and sensitive to the operating Hospital environment. They worked assiduously to satisfy their client.
- Eric Schultz, Project Manager at C.W. Driver
I have been working with Countywide for over three years at the Naval Medical Center in San Diego and they have proven to be a reliable, honest and well-respected company. Countywide makes every effort to put the client and their team members first by providing innovative solutions, quality products with a professional field staff, and a teamwork mindset that is fostered throughout the company. I have thoroughly enjoyed working with Countywide, look forward to many more successful projects with them, and highly recommend them to anyone looking for their type of services.”
