We lucked out (truly) and found a 2E adult who was also the parent of a 2E kid so she got giftedness in spades. She even took our insurance. When I spoke to her about DD the first time she said "Oh she sounds so much like me. I'm dyslexic but I went to Harvard." Don't count on lightening striking twice, though. Even our wonderful find has stopped taking insurance. I know several parents that have had to change providers every year or so to stay with their insurance coverage. Depending on your child this may not be the best option. Some folks find that going out of network costs only a little more and allows them to work with whoever they feel is best for their child.
Our wonderful person trained at the Anna Freud Center in London. She may have been equally fabulous if she had trained elsewhere or this may be a good search criteria to find someone in your area.
Also ditto to HK's comments regarding letting your DD be involved and finding someone who will call her on her "stuff". Some gifted kids would likely see through any sort of patronizing nonsense and have little respect for someone who let them totally steer the ship.
Good luck! Word of mouth is probably your best bet so try to plug into a local group for parents of gifted kids if you can.
