Instructor in Northern VA

Does anyone have a recommendation for an instructor in Northern Virginia? Or a recommendation for how to find one who's really good? I took lessons once before, but the guy was teaching me a non-traditional swing, and I don't think it was right for me. I'd like to find an instructor who really knows the golf swing in and out, who won't impose a swing philosophy on me, but rather will look hard at what I'm already doing, point out the pros and cons, and give me specific instruction on how to correct the flaws.

Can't help you in Northern VA, but the instructor I used in MD did pretty much what you are looking for with me.

I would suggest going to your local courses and talking with the instructors to get a feel for what they do during their lessons and what they tend to focus on.
