No. Unless you have arranged to do so with your therapist as part of the process, it is unlikely a therapist will allow this. Boundaries are very important to therapists, and are considered a key part of the therapeutic process in many types of therapy.
You may, of course, contact your therapist for organisational reasons (e.g. to arrange appointments). You will find your therapist's contact details in your confirmation emails, as well as in your Helpspace account under My Counselling Sessions.
