Long-Standing Leadership
Our core team has served together since 2010. Continuity compounds into craft.
“We build it like we own it.”
Every decision on site, every line item in a budget, every phone call to a trade partner — handled as if the project were ours. That's the standard, and it's the reason owners partner with us again.
Under the leadership of CEO / President / Owner Barney Addamo, GC West provides a highly skilled and efficient team (including a LEED® Accredited Professional) with extensive expertise in all aspects of the construction process — conceptual design, pre-development, preconstruction estimating, and construction operations. The team has a broad range of experience including high-density urban infill development and construction technology and management for Type III, Type III Modified, Type V, and Type V Modified construction, and has successfully achieved approvals on Alternate Means and Methods with building departments and City Boards of Appeal.
Our specialty — Type III, Type III Modified, Type V, Type V Modified — is a discipline. We study it, refine it, and repeat it. We believe the narrower the discipline, the broader the impact.

Leading GC West with a team that has served together since 2010. Barney’s approach pairs institutional-grade rigor with the hands-on judgment of a lifelong builder.
Barney is the owner and president of GC West, bringing more than 45 years of leadership in construction, development, and operations.
Before rebranding as GC West, he owned, in part, the same trusted team, proven expertise, and legal entity formerly known as ReyLenn Construction.
His expertise spans high-density urban infill development and the construction and management of Type III, Type III Modified, Type V, and Type V Modified projects. Throughout Southern California, he has successfully secured approvals from building departments and municipal boards of appeals for alternate means and methods.
Barney has led the development of award-winning projects across a broad range of product types, including affordable and luxury multifamily housing, small-lot condominiums, high-density multistory urban developments over parking structures, and the site development and infrastructure of master-planned communities.
Earlier in his career, he served as Regional Senior Vice President of Construction Operations for MGI and its affiliate, Morgan Construction Company, as Director of Operations for Irvine Apartment Communities (IAC) San Diego, followed by roles as Development Manager and Vice President of Operations for KB Home’s Urban High-Density Division in Irvine, California. At KB Home, he directed all aspects of the company’s urban construction projects throughout Southern California.
His experience encompasses the full development lifecycle, from conceptual design, predevelopment, and preconstruction estimating to land acquisition, contract negotiations, joint venture relationships, and construction operations. Over the course of his career, Barney has delivered numerous award-winning communities across California.
Jennifer McKinley is Director of Operations at GC West, where she draws on more than 20 years of experience to build strong relationships and align interests to deliver successful project outcomes for all stakeholders.

With hands-on involvement throughout the construction lifecycle, Jennifer works closely with developers, government agencies, and consultants to keep projects aligned and moving forward.
Before helping to form GC West, Jennifer served as Senior Project Manager at its predecessor, ReyLenn Construction, and as Development Project Manager at The Morgan Group, Inc., where she led entitlement and pre-construction design teams. Earlier, as an Internal Staff Auditor at Webster Financial Corporation — a $70 billion financial institution — she provided oversight across business and consumer banking, national mortgage lending, and regulatory compliance. Her background also includes architectural construction defect investigations.
Jennifer is a LEED® Accredited Professional with a specialty in Building Design and Construction, a credential awarded by the U.S. Green Building Council that underscores her commitment to sustainable, high-performance building practices.
