Pacific Empire Builders is committed to delivering high quality housing, retail, office and industrial projects for clients and end-users alike on schedule and within budget without compromising safety.  The Company performs pre-construction, construction management, and general contracting services for its clients.

Pacific Empire Builders was established by Dan Mahoney and Jason Tolleson, the founders of Serrano Development Group, a full service real estate investment and development firm.  After hiring outside general contractors to build their first few projects, Dan and Jason determined that cost, schedule, and quality objectives would be more readily achieved  by aligning the development and construction teams more closely.  Headquartered in Glendale, Pacific Empire Builders is the preferred builder for Serrano Development Group.  Pacific Empire Builders is integrated into the development process early to collaborate and work closely with the architect and design consultants to produce the optimal design.  During construction, Pacific Empire Builders works closely with the development team to identify value engineering opportunities and minimize cost and schedule impacts from changes.  By avoiding the pitfalls of the traditional owner builder roles, the Pacific Empire Builders and Serrano Development Group teams work together to design and build high quality buildings in a timely, cost-effective, and safe manner.
