Strengths:  Smart and practical attorneys, lower billable rate than mega-law firms
Weaknesses:  Many new practice areas in a short period of time, how to get a unified vision for the firm
Opportunities:  See strengths + the nature of the law firm industry whereby the "old guard" of high billable rates, lack of creativity with billing practices, lack of serving as an advisor to the client is going away.
Threats:  Law firms that are already seeing the opportunities, maybe have more presence, more marketing dollars to create more buzz - essentially first to market concepts.
