There's a nice article over on Law.com's Small Firm Business page by Kimberly Rice titled "How Can law Firms Help Their Lawyers with Marketing?" with some great tips.
Kimberly discusses the basics of practical business development and notes that just throwing time at marketing is not a good use of an attorney's time or skillset. She's well qualified to talk about marketing too, judging from her marketing website.
She wisely points out that "One of the most valuable lessons firms can learn from this recession is that their overall health depends upon attorneys who are well educated and disciplined in the nuances of the business development process."
Take a minute to read the article and you'll likely find it worthwhile for your own practice too.
