How IDD providers in California get more referrals
The short answer
In California, many new IDD clients reach providers through regional center service coordinators. The providers who get referred again are the ones who answer quickly, say clearly what services, areas and start dates they can offer, and keep the coordinator updated after the family calls.
Who refers families in California?
The main state agency is the California Department of Developmental Services (DDS). Locally, referrals often run through California's 21 regional centers, which coordinate services for people with developmental disabilities and work with vendored providers. Program rules change, so confirm enrollment and eligibility details with the state agency rather than relying on any marketing guide, including this one.
What should I do to get more referrals?
- Treat each regional center as its own referral market. Learn who coordinates intake for the services you provide and what they need from a provider to make a referral.
- Respond to service coordinators the same day with availability, start timeline and the areas you cover. A clear yes or no is more useful to them than a slow maybe.
- Keep your vendored service types and catchment areas accurate on your website so coordinators and families can check fit before they call.
How fast should I respond?
Same day for coordinators, and within minutes for families when you can. Coordinators often contact several providers for one person, and families make calls in the evening when the office is closed. Measure your own response time for a month before changing anything, so you know your starting point.
