What Centennial Realty Advisors does

Centennial Realty Advisors, LLC is a Denver-based commercial real estate management and investment firm founded in 2003 by Ken Gillis, a former Western Regional President of LaSalle Partners' Leasing and Management Group. The firm provides property management, asset management, commercial leasing, construction management, and ARGUS-based financial modeling services for office, industrial, retail, and mixed-use properties, with a stated focus on the Colorado Front Range. Centennial currently manages approximately 2.6 million square feet across roughly 19 properties, including nine office buildings, an office/warehouse, and multiple mixed-use developments, with lifetime activity spanning 52.3 million square feet managed, $1 billion of properties asset managed, $200 million of properties acquired, and 3.5 million square feet of leases negotiated.

The company's service offering is built around an owner-mindset management approach, with custom ARGUS financial models developed per property to evaluate strategic decisions, plus operational systems refined over three decades covering emergency response, preventive maintenance, and budget management. Its client base includes federal government agencies (Department of Transportation, VA Golden, National Archives & Records Administration, U.S. Geological Survey) and enterprise tenants/investors (e.g., Pfizer Boulder Campus), with notable assignments including Catalyst (a 141,000 SF new-build in Denver's RiNo District), Pearl West (Boulder), Clayton Lane (Cherry Creek), and 1644 Platte Street.

Commercially, Centennial operates a relationship-driven, sales-led go-to-market focused on the Colorado Front Range, with no public pricing, no disclosed technology platform beyond standard ARGUS tooling, no external funding, and a privately-held LLC ownership concentrated among founding partners. Revenue is derived from negotiated property management fees (typically per-square-foot or percentage-of-revenue based), leasing commissions, and construction management oversight.
