Currently, I use Genbook to Service the one remaining doctor I work for, who is a Naturopathic Provider.
In the past, I used Genbook to service an Alternative Healthcare facility with about ten employees, and we had about five on the platform at one time.
Not everyone in the organization chose to use Genbook, but that was for reasons such as payment to the doctor who owed the facility, and they already had a stand-alone booking system that they wanted to use.
We really liked that the product was web-based and the fact that you can have multiple users, but restrict access to each specific account.
Our practice enjoyed the virtual booking aspect- this really helped limit the number of incoming calls for booking appointments.
