Meet the DNG Staff


Amy Mabe – Office Manager 

I was born and have been raised in Georgia and have now started my own family here. I have been blessed with a support group full of family and friends and enjoy photographing the moments we share together. It’s been a pleasure to come back to the city where I was born and work for two committed and respectful physicians.


Tammy Frazier – Billing Coordinator

I have lived in the Atlanta area all of my life. I was born right here at DeKalb Medical Center 47 years ago.  I have been married for 26 years & I have 3 grown sons.  I met my husband in high school & found out that our grandfathers fox hunted together way back when. Actually our families knew each other all of their lives.  We live off of Frazier Rd right here in Decatur and Frazier Rd is named after my husbands family.  I went to the same elementary school as my mother, my grandfather, & my great-grandfather. It was Rehoboth elementary school which is no longer a school. I have worked with these 2 wonderful doctors for over 7 years. I will look forward to meeting you  when you come see us!


 Lisa Hattaway – Medical Assistant

I have lived in Georgia my entire life. I received my medical associate degree from Gwinnett Technical College in 2005 and have been working in neurology ever since. Some of my hobbies include reading, traveling, and spending time with my family and friends. I have an dog named Susie and a cat named Midnight. I thoroughly enjoy working in the neurology field. Helping make a difference in someone’s life has always been a passion of mine.


 Amaki Tovieku  - Medical Assistant

I’ve been a medical assistant for over ten years. Being able to work with Drs. Olson and Turknett has been a wonderful experience and I am grateful for the opportunity. I am originally from Atlanta, GA and currently live in Decatur. I have a teenage son whom I adore very much. My parents have always been supportive, and I am extremely blessed to have them in my life.
