Lillibridge Healthcare Services is a property management and leasing company focused on outpatient medical office buildings throughout the United States. Founded in 1990 by Todd W. Lillibridge in Chicago, the company initially operated as a service provider managing healthcare real estate portfolios for health systems before transitioning into ownership. The firm formed a private REIT in 1999 and was acquired by Ventas (NYSE: VTR) in July 2010, becoming the wholly owned property management and leasing subsidiary of the S&P 500 healthcare REIT. The company's investment strategy centers on acquiring and managing medical office buildings strategically located on or near hospital campuses and medical centers. Lillibridge provides integrated services including property management, leasing, facility development, and advisory services to hospital systems and healthcare providers. Following Ventas' acquisitions of Cogdell Spencer in 2012 and American Realty Capital Healthcare Trust (HCT) in 2015, Lillibridge expanded its portfolio to become a national platform managing medical office properties across 35 states. As of February 2026, Lillibridge manages 366 outpatient medical buildings comprising over 18 million square feet of space. The portfolio serves more than 100 health system partners, approximately 1,200 hospital tenants, and over 2,100 physician tenants. Properties are positioned on or adjacent to hospital campuses in core markets, creating proximity to healthcare systems and patient populations. The company operates under Ventas' broader healthcare real estate strategy but maintains its distinct brand and operational structure. Since 2016, Lillibridge has invested over $500 million in capital improvements to its medical office buildings, placing the company in the top quartile for tenant satisfaction in the Kingsley Survey. The firm partnered with Disney Institute in 2016 to enhance tenant experience protocols and conducts annual tenant satisfaction assessments. Lillibridge maintains recognition in the Grace Hill-Kingsley Survey's Elite 5, ranking among the top five medical office real estate companies for tenant satisfaction.
