## About

GenHenn Capital was established in 2022 by Michael J. Hennessy Jr. after the deaths of his parents, the founders of MJH Life Sciences. The firm operates as the single-family office for the Hennessy family and maintains its headquarters in Cranbury, New Jersey. The office invests in Seed and Series A companies across life sciences, healthcare, and biotechnology. It structures positions through equity and convertible securities and has completed 17 investments to date. Allocations remain concentrated in North America. The strategy pairs capital with operational support drawn from the family’s experience building MJH Life Sciences. The team consists of three named professionals. Michael J. Hennessy Jr. serves as Founder and Chief Investment Officer while continuing as CEO of MJH Life Sciences. Bill Hagaman acts as Advisor and Raul Martinez serves as Vice President. The office also oversees the Mike and Patti Hennessy Foundation, which supports hereditary-disease research and STEM education. GenHenn Capital remains unregistered with the SEC because it serves only family clients. This structure limits external capital raising and keeps decision-making inside the family and its small advisory group.
