An Executive Search Leader



The Hennessy Group began in 1999 as a preferred vendor in retained executive search for some of the world’s largest pharmaceutical, chemical and industrial companies. After years of building relationships with Board members, CEOs, CHROs and other senior executives of these large companies, Hennessy was a key player in the shift toward moving seasoned executives from Big Pharma and the life sciences divisions of chemical/industrial conglomerates into investor-backed startups and early-stage life sciences companies. Over time, Hennessy evolved its retained search business to focus exclusively on finding leaders for the life sciences industry.

Today, The Hennessy Group serves established and startup organizations of all sizes as an executive search firm of choice for pharmaceuticals, CDMO, biologics, biotechnology, medical devices, diagnostics, specialty pharma, and related life sciences companies. Using a dedicated team of life sciences professionals focused on client success, we find, develop and deliver leaders in life sciences using the same passion and commitment that established our reputation as a favored retained search firm among industry giants over 20 years ago.


Like you, we are passionate about the development of therapies and medical advancements that help people live better, more productive lives. We contribute to this mission by connecting the right leaders with the right companies at the right time. We are proud that many Hennessy placements have been at the forefront of some of the most important medical discoveries and therapies in life sciences. Our commitment to life sciences is to connect the most talented people to the industry’s most promising companies.
