Chang-Castillo and Associates

What Chang-Castillo and Associates does

Chang-Castillo and Associates (CCA) is a privately-held language services firm headquartered in San Francisco with a regional office in Paris and additional offices in New York, Toronto, and Ottawa. Founded in 1993 by Pablo Chang-Castillo, the company is exclusively interpreter-owned and its roster comprises AIIC- and TAALS-certified conference interpreters, many trained at the Monterey Institute of International Studies, providing simultaneous and consecutive interpretation for governments (G8/G20), international organizations (UN, EU), and Fortune 500 companies. Repeat named clients include the Salzburg Global Seminar and the Tokyo 2020 Olympic Games. The service portfolio spans written document translation, simultaneous and consecutive interpretation, Remote Simultaneous Interpretation (RSI) and Hybrid Interpretation for virtual events, ISO-compliant interpretation equipment rentals (booths, consoles, receivers, microphones), and subtitling/transcription across 50+ languages.

Revenue is generated through quote-based professional services engagements and equipment rentals. Pricing is non-public, project-by-project, with bulk discounts and rush-turnaround options; service delivery relies on a credentialed freelance interpreter network accessed through AIIC/TAALS memberships and the Calliope Interpreters partnership (where the founder serves as US representative). CCA bundles native-language translators, a documented three-step quality control process (translator-editor-proofreader) on each translation, and turnkey multilingual event management — including audio-visual equipment and on-site technicians — into its package offerings. Operating geographies span ten countries across North America, Western Europe, Asia Pacific, and Africa, with core presence in the largest interpretation markets (San Francisco/Silicon Valley, Paris for EU/UN access, New York for the UN, Toronto for bilingual corporate demand, and Ottawa for the Canadian federal government).

The go-to-market is consultative direct sales targeting senior buyers at government, international organization, and large enterprise accounts, supported by thought-leadership content marketing via a company blog and professional association referrals. Distribution is asset-light: interpretation is delivered in-person on-site, remotely via RSI platforms (Zoom, Skype, GoToMeeting), or in hybrid formats, with equipment drop-shipped alongside interpreters. The company maintains no disclosed institutional capital, no parent company, and reports 1-10 core employees, with the bulk of interpreter capacity drawn from its certified freelance network rather than W-2 headcount.
