$9.1 MILLION SPENT ADVERTISING FOR MEDICAL CLINICS
We’ve Learned What Each Message Needs To Look Like, Each Call Needs To Sound Like, From Living In The Trenches Since 2017.



125 in-house call center reps hired & fired
We’ve booked thousands and thousands of appointments in-house for our clients. And our team carries far vaster experience managing in-house call centers of 300+ active agents. We’ve learned what medical practices need and how to do it at scale.


We had 2 full-time Quality Assurance reps regularly listening and reviewing each conversation, but countless things were always missed.
