Meet our Dental Family

A dental front desk employee is responsible for helping run the dentists' office. They are the first person to greet you in the office with a smile and coordinate appointments, billing, insurance and follow-up calls.


Liz Hendley-Ramos, Business Manager

Liz received a BA degree in Education from the University of Virginia.  Rather than going into teaching, her love of music lead her to a thirteen year career as an entertainer throughout the Southeast. It was during this time that she had the privilege of headlining one evening at America’s fabulous “The Grand Ole Opry”. However, her favorite gig was at the 1992 Olympics performing three weeks on a cruise ship docked in Barcelona harbor acting as a floating hotel.  Many of our patients were followers of Liz’ music career and seeing her evokes memories of her at the Sandy Springs jazz club, Café 290. It was after the Barcelona Olympics that she decided to defer her music career and put her accounting and business management skills to work as business manager for Dr. Coggin. Little did she know that her career in the dental field would become even more rewarding than her career as an entertainer.  Her twenty-year relationship with so many of the wonderful patients and staff members of the  Coggin Dental Group has been a true blessing for Liz. Liz and her husband reside in Marietta with "Zip" the cat. 

Bonnie Machin, Patient Care Coordinator

Bonnie has been employed as the front desk coordinator since 1998.  She enjoys assisting and getting to know our wonderful patients.  Prior to working for Dr. Coggin, Bonnie was employed in the travel industry.  While working for Frontier Airlines, in the reservation sales department, she was promoted to Quality Assurance Supervisor and wrote their customer service training manual.  She has lived and worked in England and Taiwan and was privileged to have traveled to twenty four countries and to many states in this country.  Bonnie enjoys reading, hiking and being with her family.

Diane (Dee Dee) Lancaster, Front Office

Dee Dee is the newest member to our family. She has been with us since the spring of 2010.  She worked in dentistry for eight years before taking time off to raise her family.  As her family grew more independent, she went back to work in the Fulton County School system as an Administrator’s Assistant.  Dee Dee is one of the first smiling faces that greets you in our front office.  When needed, she is also able to assist us in the back chair-side.  She lives with her husband of 31 years and their Jack Russell terrier.  She and her husband enjoy their family, which includes their first grandson, traveling, cooking and being with friends.
