This is the broad view of my calendar. Clients who have already applied and had their consultation can book sessions by clicking "Office Hours" or directly at Calendly.
I use Meetup.com to organize and advertise the group support calls, but the calls themselves take place over Zoom. (I might change the platform if it's too much of a pain.)
The forum for mental health professionals is not time-specific but I do try to have new posts up twice a week and I will be moderating as needed.
