In 2005, co-founders Arnold Valencia and John Koos started Core Development Services to combine their years of real estate siting and land use entitlement expertise.

Since then, Core has facilitated thousands of real estate deals and permits for our clients.

Our relationships with key city and county professionals are vast.  We cut through the red tape to get your project to market faster.

 

 


Jurisdictional relationships are a cornerstone of everything we do.
— John Koos, President, Core Development Services
