THERAPlatform is a service where the primary feature has always been telehealth and the practice management system has grown around it.
Jane, based in Canada, has been around for several years. Only more recently, however, has it become a viable practice management system marketed to behavioral health practitioners, especially those in the United States.
TherapyAppointment 2.0 has arrived (2019), and it looks great! TherapyAppointment was one of the first applications in this market that serves solo and group behavioral health private practices.
