Best facial laser dr. in DFW area (mouth wrinkles)

Would like to find out who's the best in this area.  I've been told Rod Rohrich at UT Southwestern is good along with Dr. Robert Anderson in Fort Worth.  Since I'm probably going to have to have an ablative laser done, I want to be absolutely certain who I go to knows what they're doing and consistently turn out good results.  I should say, having ablative laser done scares the heck out of me because of all the things that could possibly go wrong.  Has anyone had ablative laser done and been very happy with the dr. and results?  If so, who did you use.  I attached a picture of my mouth wrinkles so you know what I'm dealing with.
