Science Care
Science Care operates as the family office for Tom B. Johnson, who founded and grew Science Care Inc. — a tissue bank accredited by the American Association of Tissue Banks — into a major provider of donated human tissue for medical research and surgical training. The firm's wealth originates from that regulated healthcare business, which processes and distributes non-transplant tissues to researchers and educators. The office maintains a concentrated investment focus on healthcare services, biotechnology, and life-science companies where the family's operational knowledge provides an edge. Portfolio activity includes direct stakes in regenerative-medicine startups and clinical-research organizations. Geographic exposure centers on the United States, with select moves into European life-science hubs. The firm participates in both growth-equity rounds and late-stage private placements. Deployment scale and number of professionals remain undisclosed. The office operates from Phoenix with no publicly listed additional offices. Johnson's network within the tissue-banking and biomedical research communities supplies proprietary deal flow unique among family offices. The Stoddard family office in Phoenix sometimes co-invests alongside Science Care. What distinguishes Science Care is its asset-backed wealth origin: the tissue bank business generated cash flows from a highly regulated, ethically scrutinized industry — giving the family office an unusually grounded sourcing model. The office does not manage third-party capital and has kept its investment team lean, relying on Johnson's direct operational background.

Does Science Care invest only in healthcare?
Publicly available information indicates a strong tilt toward healthcare services, biotech, and life sciences — sectors directly tied to the family's operational background. No evidence suggests meaningful exposure outside those areas.
How does Science Care source proprietary deal flow?
The family's network within tissue banking and biomedical research — along with leadership roles in medical and scientific advisory boards — provides access to early-stage healthcare companies that may not approach traditional venture firms.
Is Science Care a single-family office or does it manage outside capital?
