Dentist-Developer Builds Bilingual AI Receptionist in 2 Weeks

Dr. Erfan Zarger, a practicing dentist and developer, built two AI receptionists — one in English, one in Spanish — in just 14 days using the NexHealth Synchronizer API and VAPI. After-hours missed calls dropped to absolute zero with no additional headcount.

The Challenge

Potomac Dental Center was missing after-hours calls, losing potential patients to practices with 24/7 coverage. Hiring additional staff was cost-prohibitive.

The Solution

Dr. Zarger used the Synchronizer API to give his AI agent live access to appointment availability, provider schedules, and patient data from Open Dental — his practice management system. Using VAPI for the voice layer, he built and deployed both English and Spanish AI receptionists in two weeks.
