Dr. "Z" is 100% business man... he doesn't see any patients, he just runs his business.
I checked around to see who I'd be comfortable with for lasik... I had a hard time with his optomitrists. They seemed rather inexperienced. I don't know about you, but I'd rather be treated by someone who's good enough to open their own business, rather than someone in the lower half of their med class who wasn't good enough to make it on their own.
I know I'm makeing broad generalizations there, but that's how I feel.
