Gary Betz, DDS with Southwest Dental Group in Phoenix (Ahwatukee)
Dr. Betz was nice, but the office...well it seemed to be the unfriendliest, coldest dental office I've ever been to (out of 6-7 in my lifetime). I used to complain that dentists' offices were too full of perky, chatty, overly friendly clones, but now I miss those offices. I saw nary a smile or warm greeting - businesslike efficiency seems to be the norm here. Dr. Betz was friendly and smiled, however. No complaints about him, other than my feeling that everything was rushed. We didn't go over my history or much of anything, but we'll see if the next visit is better. 
Postscript: After getting home from this appt. and reading the horror stories on various review sites relating to ALL Southwest Dental offices, I changed my designated dentist and went to Foothills Smiles instead. Please see my review of Foothills Smiles on Ray Rd.
