Greg G, the family law attorney on my team, reminds us that he always gives his cell phone number to client. 

 I had a client who was going through a divorce and several times he complained about the lack of accessibility and communication from his attorney.  It was easy to ask, "why don't you call their cell phone if you can't reach them at their office"..Less than a month later, my client had had enough and asked for an introduction to Greg.
