Dentistry Team in Orange, CA

Orange CA dentistry team member CoraCora, RDA

I’ve been in the dental field for 25+ years starting off as an RDA in the back. Moving to the front where I greet all our patients with a smile while handling all insurance needs. Have developed personal bonds with many of Dr. Michelsen’s patient’s over the years which are like family to all of us. I have one fantastic son and the best daughter-in-law whom I enjoy spending time with plus family and friends. I enjoy traveling, reading, outdoors and have the most infectious laugh. Welcome to our family!

My favorite part of dentistry is helping Dr. Michelsen give our patients the smile they always wanted. I have a handsome 7 years old son. My hobbies are going on hikes, going to the gym, going to church, and hanging out with friends and family!
