Word of mouth is by far the best. Ask other physicians/professionals that have similiar incomes as yours and go with someone they have had good luck with.
Do not be afraid to 'interview them'... meet with a few different ones if you do have the luxury of options and go with someone that you feel you can be comfortable with.
Call them up, say I am Dr so and so, and you were recommended by so and so. I would like to visit with you about my taxes/futures. Most will be more than happy to do so as you are a potential fat (money) customer of theirs...
