Built by a Dentist, For Dentists
Calla was created by Dr. Mena Youssef, a practicing dentist at No BS DDS in Fresno, California. When launching his practice, Dr. Youssef struggled to hire front-desk talent with premium, fee-for-service experience. After months of searching, he turned to AI—designing an inbound receptionist that answers instantly, books patients, and logs every detail for his team.
The origin story
In the early startup days, staffing was tough. The first biller left after a transition into a new office, forcing Dr. Youssef to learn billing and insurance workflows himself. That experience revealed how much is on a front desk’s plate—calls, booking, FAQs, and constant context switching.
To protect patient experience and keep growth moving, he prototyped an AI that could handle inbound calls, schedule visits, and keep a clean record of every conversation. It worked so well at No BS DDS that he asked the dental community if they wanted it too—an Instagram poll came back with ~75% saying “yes”.
That’s how Calla became a service: the same AI receptionist used in a real office, now available to practices that want fewer missed calls, faster booking, and better visibility.
