Not a dentist, but a vet and I know it's not that different. So we are clinicians we are crap at admin etc. So normally the practice manager would do everything from organising staff rotas to making sure there are enough tea bags. Things that my practice manager does is negotiates uitlity bills, organises rubbish collection of all types, pays the money into the bank, pays all the bills, chases me about my tax return, does staff wages, she runs all my management accounts and places them under my nose and finally she makes a very good cup of tea. The qualities I look for are organisation, the ability to self manage, good book keeping skills, the ability to nag me until I actually do it, ability to keep track of several different projects at a time and finally the ability to prevent all those nasty sales reps from anonying me. Oh yes also makes a good cup of tea did I mention how important that is. Most of us don't know what we want out of a practice manager and the role evolves has it goes along. She is also an excellent listener and very discrete.
