Mark Caputo founded Liberty Dialysis on Mercer Island in 2002 with Bob Santelli, backed by Bain Capital, KRG Capital and Seattle's Ignition Partners, and grew it to roughly 260 clinics before selling into Germany's Fresenius Medical Care in a deal reported at $1.7B and closed in 2012. He stayed at Fresenius as managing partner for joint ventures, chaired Sound Physicians until 2018, and is now chairman and chief executive of U.S. Renal Care, the dialysis operator based in Plano, Texas. Harvard MBA.
He is not the political journalist Marc Caputo, who is a different person with a different spelling and no aircraft.
Two airframes, both status valid, both with the registered owner NAME withheld under the FAA's privacy program — the Mode S hex is still published for each, so both track normally. N80QJ is a 1998 Gulfstream G-IV, serial 1333, hex AAE0EB. N650C is a 2012 Gulfstream G650ER, serial 6021, hex A88CEC. Both records were last touched on the same day, 24 August 2025, which is the sort of thing that happens when one owner files for both at once.
The holding entity is reported as Mercer Air LLC, a Washington company incorporated in October 2010 whose officer list includes a Mark Caputo; there is also a Mercer Air II LLC at a Mercer Island address. That comes from third-party mirrors of the Washington Secretary of State rather than from the state's own system, and because the FAA name is withheld there is no federal record joining the aircraft to the LLC at all. So: the airframes are confirmed, the owner is inferred, and no news outlet has ever written about either jet.
