I'm happy to write this letter of reference on behalf of Bill Potabi and his team at CMM Sitework. Over the past several years I've come to rely on CMM Sitework to perform many aspects of my construction projects. From whole house drainage, to lot clearing, site work, excavating, grading, and installation of septic systems and drywells, Bill and his employees have consistently worked in a professional, and workmanlike manner to execute all of the tasks for which they have been engaged.

We at Paramount put a big emphasis on being a “team” and I am happy to say CMM Sitework is a valued member of our team along with all our other vendors that together execute projects quickly and efficiently in perfect harmony. Bill has proven to us his outfit can handle any scope thrown their way whether it be a single home or drainage infrastructure and roadwork for an entire sub-division.
