CHICAGO, IL (October 14, 2026) – DHR Global, a leading global talent advisory firm, announced the acquisition of Discovery Search Partners, a retained executive search firm delivering innovative solutions for the Life Sciences industry.
Bill O’Callaghan of Discovery Search Partners will join DHR as Managing Partner and Don Evans will join as Partner, while Brian Evans will bring his expertise to build out the Life Sciences vertical at Jobplex, the emerging leader search business of DHR Global. Together, they bring deep expertise across the medical device, diagnostics, pharmaceutical, and biotechnology spaces, significantly expanding DHR’s Life Sciences practice.
“The depth of experience and tenure across the Discovery Search Partners’ team greatly elevates our ability to find high-caliber leaders across the Life Sciences industry,” says Priya Taneja, CEO of DHR Global. “Their reputation and standard of excellence in the space are unparalleled and perfectly align with what we look for in DHR partners.”
Founded by Bill O’Callaghan and Don Evans in 2009, Discovery Search Partners has successfully found leaders for a wide range of clients in the Life Sciences space, from multinational Fortune 500 companies to pre-revenue start-up enterprises. Their move to DHR unlocks their ability to offer their network a broader range of talent solutions and a global infrastructure to scale support.
“Discovery Search Partners was built on doing right by clients and candidates, and in getting to know DHR’s people, we saw that same commitment and felt the same values,” says Bill O’Callaghan, now Managing Partner at DHR Global. “DHR’s collaborative culture and global office network will enable us to grow our Life Sciences work further and faster than we could as an independent firm and carry forward the legacy of what was started at Discovery Search Partners.”
“Emerging leaders represent the next generation of executives, and Life Sciences companies need that bench as much as they need strong leadership at the top,” says Justin Hirsch, CEO of Jobplex. “Brian brings the relationships and industry knowledge Discovery Search Partners has built since 2009, and he will lead the build-out of our Life Sciences vertical so clients can work with one connected team, from the C-Suite through the next generation as well.”
The acquisition marks a significant step in DHR Global’s continued growth in the Life Sciences sector. Clients of Discovery Search Partners will continue to work with the same trusted team, now supported by DHR’s global reach and full suite of talent solutions, from executive search and leadership consulting to emerging leader search through Jobplex.
