Richard K. Mellon and Sons
Richard K. Mellon and Sons operates as the dedicated wealth office for one branch of the Mellon family. Seward Prosser Mellon serves as president and chief executive. The firm traces its mandate to the preservation of family capital originally built in banking and industry. The office allocates across healthcare services, industrial technology, and sports and wellness. It uses alternative venture models, direct co-investments or SPVs, and mission-related investments. All activity remains within North America. Confirmed holdings include residential estates and land parcels in Ligonier, Pennsylvania, alongside the Mellon family art collection. The firm reports no additional offices. It maintains long-standing memberships at Rolling Rock Club, Lyford Cay Club, and Quissett Yacht Club.
