We tend to remember the impression we had when we left a lawyer's office as well as our first impression upon entering. Try to send your clients away with smiles on their faces. Reinforce their feeling that they chose the right lawyer for their work. Thank them for selecting you as their lawyer. Let them know that you value their confidence in you.
People approach lawyers with real fears.
Of course these fears build or diminish depending on their prior experience with lawyers. Tell them exactly what you can and cannot do. Let them know if their expectations are within the range of what you may be able to accomplish. If, in fact, they do not need a lawyer, tell them so. If they do need you, praise them for making the right decision and for choosing you.
