Commitment to Healthcare Real Estate

Our commitment to the healthcare industry stemmed from a need we observed in the early 1990s as healthcare providers were increasingly looking to develop and expand their ambulatory networks. Recognizing a need for specialized healthcare real estate planning and project management, Hammes Healthcare was founded in 1993 to address the complexities and challenges unique to healthcare providers.

Since then, Hammes has emerged as a nationally recognized leader in healthcare real estate strategy and planning, project management, development, investment and property management, working with leading healthcare providers across the country.

As a testament to our unparalleled experience and commitment to the healthcare industry, Hammes has been ranked as a leading healthcare developer by Modern Healthcare’s Construction & Design Survey for 25 consecutive years—20 years as No. 1—and by Revista’s Outpatient Healthcare Real Estate Development Report.
