This is done in an attempt to keep the list focused on our top specialties and for reasons of fairness to clients and other therapists in the directory.
There are 77 "Areas of Emphasis" on the list and it is tempting to check all the areas we have interest and some expertise in. Also, we are in a friendly competition with other therapist for clients. If one therapist checked 25 areas and another checked 3 (that are true areas of specialty), the one with 3 would be at a disadvantage. Also, the potential client would not be as well served by this.
So we have set a limit to 4 in an attempt to focus the list. Unfortunately the system does allow you to check more than 4 (something we hope to address). So in the mean time, we will be reviewing the profiles and removing any more than 4 entries.
We hope that this explanation addresses the "Why".
