I've been going to Dr. Sieber over 8 years. She was initially recommended to me by someone who had worked for her at one time. Both she & her staff are very caring and strive to make sure you're always comfortable. Her new office on Macarthur Blvd. is super nice, very open & airy. They've extended their hours which helps those of us who have trouble taking time off from work. For me, going to the dentist these days is actually a pleasant experience.
