Hey I'm glad to hear you say that Leslie.
I've been an attending 6 years, and the last 4 solo.
I intuitively have felt that I need to know where my money is, and several people with experience in practice management have advised me the same.
However it's great to see someone a few years my senior recommending to continue doing what I am doing.
My biller helps out front but I rarely allow it. Her job is more important than answering phones. It's getting my money so I can pay everyone. however she helps me pickup the kids and take them to middle of the day doctor appts.....and other misc stuff.
