What Irgens does

Irgens Partners, LLC is a privately held commercial real estate development and management firm founded in 1983 and headquartered in Milwaukee, Wisconsin, with additional offices in Chicago (Riverwoods, IL) and Phoenix (Tempe, AZ). The firm operates as an integrated developer, owner, lessor, and property manager across four core product types: healthcare/medical office, Class A commercial office, industrial/R&D, and horizontal mixed-use. Notable developments include the 380,000 SF BMO Tower in downtown Milwaukee (acquired for $127.5M in 2017), the 358,000+ SF 833 East Michigan (LEED Gold recertified 2019), the 506,195 SF GE Healthcare Research Park (sold 2007 for $62.5M), the 66-acre master-planned Corridor development in Brookfield, WI, and a portfolio of medical office buildings across Wisconsin, Illinois, and Arizona. The firm also acts as a development manager and broker for third-party owners.

Revenue is generated through four streams: (1) rental income and capital appreciation on owned commercial, medical office, retail, and industrial properties; (2) development management fees for engagements where Irgens is retained as development manager without taking equity (e.g., Prospect Medical Commons for a major Milwaukee health system); (3) brokerage commissions on leasing transactions for both the owned portfolio and third-party owners; and (4) gains on the sale of stabilized assets. Pricing is quote/negotiation-based and not publicly disclosed. The firm targets enterprise healthcare systems (Froedtert, Medical College of Wisconsin, ProHealth Care, Children's Hospital of Wisconsin, Cigna, USPI, Vista Health), large corporate tenants (BMO Harris Bank, GE Healthcare, A.O. Smith, Michael Best & Friedrich, Silvercrest Asset Management, Hydrite Chemical, Milliman, Markel American, Trans-Coil International), and institutional capital partners via joint ventures and the Research Park Partners Fund. Customer acquisition is sales-led and enterprise-focused, supported by a dedicated in-house brokerage team (Kevin Armstrong, Alyssa Geisler), broker partnerships with CBRE and Colliers, VTS marketplace listings, and NAIOP/IREM industry association involvement.

The technology stack is conventional CRE tooling: a Mrisoftware tenant portal for availability listings and tenant login, plus standard building automation on trophy assets (touchless door and light sensors, programmed elevator service, enhanced HVAC at BMO Tower). Differentiated capabilities center on complex capital stack structuring (TIF, New Market Tax Credits, EB-5 financing, ground leases, layered mortgages), an at-risk development model where the firm commits its own equity alongside institutional partners, and a multi-decade track record of LEED, Green Globes, and Sustainable SITES certifications including Wisconsin's first LEED-certified building in the Milwaukee County Research Park (Mayfair Woods, 2007).

Revenue model

1. Commercial Real Estate Development & Ownership: Irgens develops, owns, and manages commercial, healthcare, industrial, and mixed-use real estate properties. Revenue is generated through development fees, property leasing (rental income), and capital appreciation upon sale of owned assets. Properties include Class A office buildings, medical office buildings, retail centers, and industrial facilities in Wisconsin, Arizona, and Illinois. The company acts as both developer and equity investor in many projects.
2. Leasing & Tenant Representation: Irgens brokers leasing transactions for its own portfolio as well as third-party owners. Brokerage commissions are earned on new leases and lease renewals for commercial and medical office tenants.
3. Development Management Services: Irgens is retained by health systems and other property owners to manage the development process (site selection, financing, design, construction oversight) as development manager, earning fees for these services without necessarily taking equity ownership.
