"To Whom it May Concern, September 12, 2014 I’ve been providing planning and project management services for commercial projects in Northern California for over 30 years. Phill Skiles and Cornerstone Construction has become one of my reliable “go-to” guys in recent times. Phill and I first started working together when he superintended for another general contractor. I was the Owner’s Representative on that project, and had the opportunity to monitor Phill’s work as he scheduled the work, managed his subcontractors and filled- in as needed with his own construction skills. During that project I found Phill to have good organizational skills and excellent attention to detail. He communicated well with his subcontractors and built a camaraderie among the workers that prompted his subcontractors to want to do their best. He was considerate of our clients and staff (it was a remodel of a working clinic), dovetailed well with other subcontractors I had hired and generally ran an efficient, clean project. I subsequently have hired Phill to superintend a project for me in the City of Clearlake, where we worked together to convert a dental office into a satellite medical clinic. I have also hired him directly to complete a variety of smaller projects, all of which have been completed on-time with considered care and craftsmanship-quality work. My experiences with Phill have always been positive. He is a likeable man who comes to work with a ready smile, high levels of honesty and integrity, craftsman-quality work and the ability to manage other workers effectively. I endorse Phill Skiles and Cornerstone Construction without any reservation. If you hire him for your work, large or small, you won’t be disappointed. However, just don’t make him so busy he can’t find time for my projects too!"

"When my commercial building was damaged by a vehicle, Phill of Cornerstone Construction handled all the negotiations with the insurance adjustor to get me the best possible settlement. Afterwards, Phill promptly scheduled the work with the least potential disruption to my business, communicated with me regularly regarding the progress, and personally completed some of the work himself. Throughout it all, Phill and his subcontractors kept the work area neat and clean. I highly recommend Cornerstone Construction."

"Phill Skiles of Cornerstone Construction was the contractor who built my house, who I've known for many years. Phill is a general contractor capable of managing a project from start to finish smoothly and efficiently. He is talented in all facets of construction, from excavation to finish painting. He works well with governmental entities with respect to obtaining required permits to choosing design criteria.

He is energetic, dependable, and reliable. In addition to getting the final on my house he also, in recent years, has helped me complete additional facets of the finishing touches. He’s on time with a friendly attitude, and is always good at knowing many ways of performing different tasks efficiently in the way they were accomplished."
