The founder's thesis

Why Third Act exists

After 30-plus years leading go-to-market execution and technology distribution, I founded Third Act USA with a singular purpose: to protect aging Americans from fragmented clinical care, predatory economic practices, and uncoordinated technology. We are building a fiercely loyal, sovereign advocate that empowers older adults to age in place with independence and dignity.

The advocate works for the member, not for the hospital, the insurer or the data broker. It keeps the member's records in the member's hands, prepares them for every clinical encounter, and watches the follow-through that the system too often forgets.

01

Fragmented clinical care

Records scattered across portals; fifteen-minute visits spent reconstructing history instead of deciding.

02

Predatory economic practices

Older adults are targeted precisely because they are trusting, busy with their health, and alone with the paperwork.

03

Uncoordinated technology

Devices and apps that each solve one problem and hand the integration work back to a 70-year-old.

Selected track record

Enterprise execution and market creation

Three decades of taking products to market in industries that had to be taught a new way to buy: data, simulation, industrial components, consumer electronics.
