John Prufeta brings an unusual combination of venture capital investing and hands-on healthcare operations, having built Medical Excellence International as a family office for healthcare that provides concierge-level care and longevity programs for ultra-high-net-worth families while maintaining deep relationships with academic medical centers across New York, London, Moscow, and Shanghai. This background gives him direct insight into how sophisticated healthcare buyers actually consume advanced therapies and what major medical institutions will adopt, which he applies through Medical Excellence Capital's focus on gene and cell therapy investments alongside his role chairing the Medical Excellence Foundation that provides grants to promising academic medical research.
