Once you have a confirmed session, you gain access to client's notes and session history. We would generally advise to read these to get an idea if the client has any injuries or have a specific goal they are currently working towards.
If this is your first session with this client, send them a text message to introduce yourself. If your venue is difficult to find, we would suggest you include directions in the intro text. You can include tips like 'there is a parking space right outside the studio' etc. Also, let client know where you are planning to meet them.
Always meet your client either reception or outside of the venue.
