Yes, I teach Heart Zones.
I also know Kathy well... she's a very enthusiastic person. I'm sure you'll enjoy having her out there in Dallas. I've been working with HeartZones now for a few years. Informally since 1999, and through the company since 2001. I also attended their first conference in Dallas in October and I look forward to their next conference this Oct. It should be fun.
Maybe I'll see you there?
