Many attorneys delegate regular communication with clients to their team. There's only so many hours in a day. An attorney's time is precious. So routing clients to staff members seems like an efficient use of the attorney's resources.
I have learned that my regular communication with my clients is more effective for their case in a variety of ways. Less information is lost in translation. Clients are more likely to do what I recommend they do. I can spot problems and head them off before they become serious. And by the time we go to court, if we go to court, I know the story, because I was in close communication with my client.
More efficient? Probably not. More effective? Absolutely.
