Co-founder & Co-owner

 I learned early in my career that to build a strong company you need professional, solid, trustworthy people.  This is the foundation on which our executive team is built.  We have over one hundred years of combined experience in providing “True Open Book” Construction Management Services.  We truly operate with a different approach than any other company, to provide an Open Book CM process that will bring our clients into the process.

Philip F. Doyle

Co-founder & Co-owner

 Over the last twenty five years running a construction company and nearly eight hundred contracts completed, we have come across and dealt with a lot different scenarios. One of the most important things you can do, is to listen and try to understand what a client wants. If we know what you want we can offer you advice, based on experience and give you options regarding particular designers or build types. I believe we provide an honest, quality and value for money service.
