 913-754-2144. They're great people, and they do great follow-up work. I can tell you, you know, I've had a couple of issues with these hearing aids. The place I was at before, not so good with service. Totally different here. I've been extremely happy with how these folks work, and it's been a very good relationship for me and for my wife, Lauren. Both of us go to Focus Training. They do a great job.
