Betty Brown, RDA
Betty worked for our practice for 11 years before retiring May 2018. She has a wealth of knowledge and experience at the RDA position and will be sorely missed. Fortunately for us, Betty has agreed to come fill in part time if needs arise in the operatories or at the front desk. If you're lucky, you'll still get to see her occasionally around the office!
Betty started her career in dentistry in 1969 in Houston. For 22 years, her husband's transfers took her to Massachusetts, Georgia, and Louisiana.
"I was born and raised in Huntsville, and have recently moved back to the area. My life has taken me many places, and I have worked in numerous dental practices.
"Over the years, I have had such great experiences and have learned so much. This led me to Dr. Rathke's office, where I have brought forty years of experience and a willing nature to keep learning and growing.
"In my spare time, I enjoy fishing and gardening. What a joy it is to be fishing, or to see something grow!"
