Leaving Synanon: the hatchery, the rattlesnake era, and Cassie's discovery

Milton and Sandy walked out of a cult rather than surrender their children — and decades later, Cassidy Arkin mapped the truth of her own conception

Jonathan Hare invented the Quantum Privacy Network and wrote this record. Berkeley 1987, Stanford GSB 1992; founder or principal at Evolve Software, Consilient, Resilient Network Systems and Quantum Privacy LLC. Nine patent filings; the foundational patent granted May 2025 with 2016 priority. This is his account, published with its sources so it can be checked and corrected.
The claim

The family's Synanon chapter ends on a refusal: when the cult mandated that children be separated into a communal hatchery, Milton Hare and Sandy — who already had Cassie — left. Decades later Cassie, an early assisted-reproduction baby, uncovered that the fertility doctor had secretly used his own sperm, and chronicled the discovery in a documentary.

How it happened

01

Synanon

Before my half-brother Harold was born, my father's path took a highly publicized detour. He met Sandy Rogers — Sandra Rodgers-Hare — while they were living at Synanon in Marin County. Synanon had devolved into a dangerous cult, culminating in the notorious scandal in which members put a four-foot rattlesnake in the mailbox of an attorney working with the Point Reyes Light newspaper during its Pulitzer-winning investigation.

02

The hatchery

The breaking point for my father and Sandy was the cult's mandate that children be permanently separated from their parents and moved into a communal ‘hatchery.’ Sandy already had a daughter, Cassie — Cassidy Arkin — and they were unwilling to surrender their family. They moved off the ashram around 1983 or 1984, right after my senior year of high school or freshman year of college. I met Cassie then; she was about five or six, and I still remember seeing her in a crib.

03

Cassie's discovery

Cassie was a pioneer of early assisted reproduction. For decades, her parentage was understood to be the result of a standard anonymous clinical donor procedure. Recently, however, she uncovered the actual mechanics of her conception: the fertility doctor who performed the procedure had secretly used his own sperm, fathering potentially hundreds of children. Because commercial sperm banks with modern ethical protocols didn't really exist back then, I view it practically — it simply wasn't disclosed. Cassie successfully mapped this reality, a journey chronicled in a documentary.

04

Harold

Shortly after they left Synanon, my half-brother Harold was born. He grew up to be a very big guy — the running joke is that he essentially guards the house, so nobody should try anything.

Restated

What it comes to

A cult that demanded the children; parents who refused; a rattlesnake in a mailbox as the era's backdrop; and a daughter who, decades on, mapped the hidden truth of her own beginning and put it on film. The family's costliest refusal and its bravest investigation, in one chapter.

  • Cassie's documentary — its title, for the record, at her pleasure
  • Harold's birth year — Hare's placeholder is ~1990, pending his check (S-095); the earlier candidates are preserved in the sources
