Just a quick aside about firms that buy up smaller firms as the primary method of expansion..
Holland & Knight still hasn't changed their growth strategy after this little fiasco, so maybe they have it under control now. And perhaps DLA is being a little more careful with who and where they buy? I have no idea. But anyways, there can be some real downsides to this expansion strategy.
There's also success stories, i.e. Baker McKenzie. Biggest firm in the world pulling off this strategy, and fairly successful to boot.
I'm not saying the strategy can't be successful; I'm just saying that more people should ask the hard questions to try find out about the firm's growth strategies and how successful they are. While you may not get straightforward answers (I'm sure Holland & Knight wasn't telling 2Ls during OCI that they were considering closing down several newer offices b/c they were losing cash), people can look and see if the firm is expanding in major vs. secondary markets, ask about the kind of clients each office services, etc.
Better to do a little research and make sure the firm you want is managing things well, like Baker McKenzie (assuming you're right about their growth - I have no idea)
