Over the years, SHI has built an exceptionally qualified, diligent and committed team of employees and consultants with extensive experience and contacts in the senior housing segment. The groundwork was laid by the company founders and managing directors. With more than 20 years of experience in senior housing investment and a sound professional background, they develop the portfolio strategies and shape the strategic investment decisions of the funds.

Our thinking is forward-looking and entrepreneurial, yet in our investment decisions we remain cautious and critical. We discuss investment decisions on the basis of well-researched facts, so we can ultimately make sustainable and smart decisions with favorable market timing.
