About this site

The McGuireWoods Healthcare Private Equity Team previously published a multi-part series highlighting some of the more active private equity investors in the healthcare space. Since the original publication, we have seen even more PE investors turn toward healthcare investments, new healthcare-focused funds form, and healthcare PE deal activity continue at a staggering pace. Thus, we have decided to launch this site to highlight investors in a more current format, as part of our ongoing service to the healthcare private equity community. These investors, listed purely in alphabetical order, are funds that primarily focus on growth-stage, buyout and platform funding transactions. The sheer number of investors is a real testament to investors’ views of healthcare as a solid investment play.
