RGC oversaw the remodeling of our Special Olympics Northern California headquarters which required the staff to move to a temporary space. The stress of remodeling can be a lot to manage, but Mike and Anthony were spectacular. They have such a high level of craftmanship and dedication to ensuring the project comes in on time and budget. Their attention to detail and ability to troubleshoot and present solutions was key to the success of the project. They handled electric, plumbing, wall demo and construction, multiple types of flooring, painting, ceiling tiles and reframinging, door refinishing, HVAC vents, installing noise cancelling, and so much more. We so enjoyed working with them. The new space inspires our staff to collaborate in the office.
