I have only dealt with one breeder here in Arizona and it was Thomas Pecanic he was very helpful nice educational willing to help me out in the future and one night even offered me some dinner while I was at his house ha ha I declined only because I had other dinner arrangements he is grade A+ breeder in Arizona in my opinion
As for north central I would say garrick demeyer he was very easy to contact more than happy to answer all my questions with extreme detail and help with some of my smaller problems overall A+++ breeder very knowledgeable in reptiles
