From Our Clients
I want to send you a very sincere thank you for working with us in all of the ways Sonnikson does each and every time we need you to. It seems like we are always in some sort of a situation that requires your help. Before we had your company it was a very difficult task to get the support needed in so many ways. It seems that my best tool in the box is your company and its ability to support us in so many different ways. We also appreciate the attention that Joe pays to the plant. I have given this opportunity to several different contractors and Joe is the only representative that has lived up to the task. Thank you.

By the way, your craftsmen and Ray Wallace are performing faultlessly.  It is a pleasure to work with Ray and he always makes me feel confident; he is a great asset!  I have also had the pleasure to interface with Leo and his team, he too always helps me when the other Sonnikson team is not on site.

From Our Clients
This is a note to let you know what we have gained since meeting Joe Griego and the company of Sonnikson construction. For years American Canyon Coca-Cola has been reaching out to many construction companies in and out of the area to support the needs of the manufacturing in this plant. We always struggled with getting qualified technicians, enough technicians or support on our time frame. Every contractor that has come before yours has up charged us just because we are very successful. We could not get real ownership in the projects or the well-being of the plant. Then came Mr. Griego. Since Joe came into the plant from an emergency job (Line two cooler bed) he has not left. Your company has showed us what we need and deserve in a contractor. Joe has built very solid relationships at this plant in the few years we have been doing business now and enjoys complete access to all of our equipment and personal. Sonnikson construction has met all of our contractual needs and has performed up to our standards and beyond. They have done this in a very transparent manner with rate sheets equipment rates upfront and no surprises. Your company has met all of our off shift and weekend or holiday needs. We are very pleased in the type of service we get with Sonnikson construction. In conclusion we are a high level manufacturing facility for the best company in the world and your company and personal align with our goals and vision for the future. Here is to many years of success for us both. Sincerely I and the whole plant thank you.
