After being treated by dr. Ziegler for four years, It is just being brought to my attention that I have wasted thousands of dollars and 4 years of my life under his care. He failed to notice apparent habits that I developed as a child and has caused my teeth and bite to shift terribly after the removal of my braces, even wih persistent use of my retainers. He also sold retainers to me that did not fit and only worsened the condition of my teeth and bite. Overall I would HIGHLY suggest finding another orthodontist to take care of your or your child's teeth.
