Certain traits run in every family. At Ralph G. Degli Obizzi and Sons, it's not to hard to tell which runs in ours. I began the business in 1969, becoming the first open shop mechanical contractor to break into the large construction industry in Delaware. Over the years, I've been blessed to have all five of my sons join the business, most of them starting as apprentices and working their way up. Ralph G. Degli Obizzi and Sons is unlike many other family-owned corporations in that each son makes a solid and vital contribution to the well being of the company. I think you will find all five share the values which permeate the operation: commitment, cooperation and caring. And, of course, we'll treat you like family.
