I might be 100% wrong but I would imagine if a new client calls their firm out of the blue to ask if they have a lawyer who can help them out, the intake person would ask the client questions to see which of their lawyers should take the case, and if it involves a lot of money maybe the intake person is commanded to give that case to the big boss... I contacted a firm without specifying which lawyer I wanted and my case was given to one of the owners of the firm even though the profiles of the other lawyers state they are experienced in that area of law as well. Most head lawyers establish a good reputation for handling complicated or big cases, they are go-getters and motivated to serve justice so I can't imagine them taking a back seat supervising others do what they love to do but these are all my guesses I'm not a lawyer.
I joined PPL for a few months. When I had a legal situation, all they would do is write one letter, and then said I had to pay a "reduced" rate for all services beyond that.
Their reduced rate is almost equal to a full non-discounted rate from a good lawyer in my city.
Yes, it took many phone calls and lots of being on hold - they tried to tire me out, but I prevailed.
I will never go back to them again - it's a waste of time & money.
