Upon arriving, you can walk right in through the front door and follow the signs to the waiting room. Once it's time for your appointment, your therapist will come downstairs to greet you and lead you to his or her office on the second floor.
Then the paperwork is finished! You and your therapist will then begin to collaborate about the most effective way to work together to meet your goals and start to work toward them. You'll also have the opportunity to ask your therapist any questions you may have about counselling, his or her approach or training, or anything else you might be curious about.
And that's pretty much it for the first counselling session. For information on the overall process of counselling, check out this page on what happens in counselling.
