1. Go to Professionals › Professionals.
  2. Add a new professional with their name and email.
  3. In the General tab, choose:
    • Show in the app: clients see them in the app.
    • Show in calendars and classes: they can be assigned to classes.
    • Available for clients to chat with.
    • Color: how their classes look on the calendar.
  4. Save.

Then decide what they can do in the panel and the app: see Panel permissions and App permissions.

The professionals list shows each one's name, email, whether they have panel access and whether they show in the app.

Tip: a professional can teach classes without panel access. Leave their panel permissions off and keep Show in calendars and classes on.
