I agree with Fallon that I'd rather have people who really want to see me make appointments. And I love the build-up and anticipation. I can't imagine screening by phone, but I know a lot do. I guess it is just what you're comfortable with. And I love nothing better than a nice, sweet email introduction.
With this method, I have been fortunate to attract those with whom I seem to have a lot of chemistry. May that long continue!
