Drs Prohaska and Buttner performed orthodontic work on my daughter. They were painless, efficient, and her results were fantastic! They are not the cheapest orthodontic doctor to use, but the results and service they provide border on the royalty treatment. If there a problem/emergency arises, they get you in quickly. They offer motivational programs for their patients who take care of their teeth during treatment and they always offer you a wonderful 'going away' gift when you have completed your care. The drs and their staff are so wonderful!
