Building Trust. Delivering Excellence. Serving You.

Founded in 1991 by Jim Carminati Sr. and Tony D’Auria, Waterbourne Construction Advisors emerged from a client-centered real estate firm’s success. We recognized the need for dedicated owner advocacy and created a separate entity, maintaining our core values.

About Us

Waterbourne was created out of a need in the marketplace for owners’ advocacy and representation. Waterbourne Real Estate Advisors, LLC was formed in 1991 by Jim Carminati Sr. and Tony D’Auria as a client centered real estate firm that focused in tenant representation and specialized in buyer’s brokerage. Many of those real estate clients started to ask for us to oversee their buildout of their new space. Since Waterbourne already established a great relationship with the owner, had keen knowledge of their budget and needs, it made sense to start a separate company called Waterbourne Construction Advisors, LLC which still focused on the client needs and allowed us the opportunity to keep that owners advocacy role the company was built off of.

Today, Waterbourne Real Estate Advisors, LLC and Waterbourne Construction Advisors, LLC are two separately owned companies. If you are looking for real estate services, please visit their website and contact Tony D’Auria. 

Waterbourne Construction Advisors, LLC is based in Youngstown, NY and is owned by father and son team Jim Carminati Sr. and Jimmy Carminati. Our values remain the same as when the company was originally formed. We are an owner advocate through and through and would welcome the opportunity to be your teammate and partner through your next project.
