I love Dr. Wirth and his staff!!
My boyfriend and his entire family see Dr. Wirth, so on their recommendation, I made an appointment with him (just moved to AZ, hadn't yet found a dentist).
Both Dr. Wirth and his dental hygienists (as well as the front office staff!) are very knowledgable and friendly. He always takes time to as how I'm doing, how my boyfriend is...very personable! I've never had trouble making a last minute appointment, as Dr. Wirth is pretty accommodating.
Oh yeah, he always does an excellent job, and is fast!
Overall, Dr. Wirth and his staff are awesome :) I highly recommend!
