30 years of building,

Justin Peter Gardiner Lowe is an American-Swiss entrepreneur and the founder of Gardiner Investments, a family office. With three decades of experience in global capital markets and investment banking, Justin has built extensive expertise in origination and capital solutions, underwriting and distribution, special situations, and global asset management.

Justin began investing in hedge funds in 1999 and co-founded Reliance Management, a leading fund of hedge funds manager that grew to over $2 billion in assets under management by 2008.

Heritage

Gardiner Family Coat of Arms

The Gardiner Legacy

Justin carries forward a distinguished transatlantic lineage that spans finance, diplomacy, and public service at the highest levels. His heritage reflects the same values he brings to his own career: stewardship, integrity, and a commitment to building institutions that endure.

He is the great-grandson of Robert Hallowell Gardiner IV, founder of the Fiduciary Trust Company in Boston in 1928 — a landmark institution in American wealth management. Through the Gardiner line, Justin inherits a tradition of fiduciary responsibility and long-term thinking that informs his approach to investment today.

He is also the great-grandson of Adrien Lachenal, elected President of the Swiss Confederation in 1896, and the grandson of Marc Peter, who served as Ambassador of Switzerland to the United States from 1919 to 1939. This dual American-Swiss heritage is central to Justin's identity and his global perspective on business and philanthropy.

First Novel

Since Ninety-One

A NOVEL BY JUSTIN PETER GARDINER LOWE • AVAILABLE ON AMAZON • MAY 2026

Justin is publishing his first novel in May 2026.

Since Ninety-One is a novel of exceptional precision and restraint. It is written in a register that is rare in contemporary fiction about war and geopolitics — forensic without being cold, morally serious without being didactic. The prose moves between a Miami terrace and a Ukrainian trench with the same unflinching attention, refusing to rank one world above the other. Sentences are built to carry weight quietly: what is not said does as much work as what is.

The structure is architectural — four storylines converging on a Geneva negotiating room in March 2025 — but the novel never feels mechanical, because each character is rendered with the particularity of someone observed rather than constructed. The back-channel diplomatic world is as precisely imagined as the dugout, and both are more morally complex than the genre conventions that surround this territory usually allow.

There are echoes of le Carré in the tradecraft and of Didion in the landscape sentences, but the voice is entirely its own. What distinguishes it finally is its conviction that bearing witness is not a passive act — that writing it down, accurately, in enough copies, is both the subject of the novel and its argument.
