American Developers Guild
The American Developers Guild

A room of serious developers, and one who has done it for over five decades.

The American Developers Guild is a private mastermind for ground-up single- and multifamily developers in California and the Southwest. It meets roughly three hours each month, by application only. It is not a course and not a coaching program — it is a working room where real projects are pressure-tested by peers and by Ron Ramos.

Format

Three hours, monthly

A standing monthly session built for working developers — focused, confidential, and structured around live deals, not theory.

Membership

By application

Seats are limited and earned. The Guild is for developers actively building or about to — not spectators, and not the merely curious.

Scope

Single & multifamily

Ground-up residential, across California and the Southwest — the terrain Whetstone and its members work every day.

Member Story

Proof, when it’s real.

From no background to a certificate of occupancy.

Kyle DeQuillettes came to the American Developers Guild without a development background of any kind. His first project — Tempo Glendale, thirty-four units in Glendale, Arizona — is now complete and holding its certificate of occupancy. He took raw dirt all the way to finished, occupied homes.

That is the becoming, start to finish: not a stock quote or an aspirational stat, but a member who did the work.

The ethos

Purpose. Grit. Focus.

The three words the Guild is built on — and the standard by which members hold one another.
