Not at all. In many cases you will be put in contact with a local Area Team Leader (ATL) or Regional Mentor (RM) who will answer any questions and give you tips and tricks.
Many ATLs or RMs will try and accompany you on your first visit, introduce you to the establishment contacts and help you settle in.
Occasionally this may not be logistically possible and please remember out ATLs are volunteers too. You may be happy to start your visiting without the support of a mentor and that’s alright too.
