Hi K.! I have been a hygienist for 7 years now and love it! I was a dental assistant for 6 years before going to hygiene school. I can tell you this: once you start in a hygiene program it is full time and very intense. I would NOT recommend working and honestly think it isn't possible to hold a job outside of all the classes and set clinic/rotations/interships. The hard work does pay off though! The going rate for a RDH is $40 per hr in the valley!I love my schedule which only consists of a 3 days work week. Perfect for a mom.
I really don't feel Dental assisting programs PRIOR to dental hygiene is necessary. I feel its a waste of time and money! Look into all the programs for a school that DOESN'T require that. The programs I have heard of out here are at Phoenix College, Northern Arizona University, Rio Salado and Apollo. I did hear that there is a school in Mesa which is starting a program very soon.
Best of luck!!
