Back Office Staff



Cheryl Harkins

Administrative Assistant, Purchasing



I am proud to say that I have been a Rabun County native for thirty-five years. I love everything our area has to offer, especially the beautiful and peaceful mountain landscape. My family is my pride and joy. I have four amazing children and a loving husband of seventeen years. I enjoy baking, gardening, and spending time with my family.

I worked in the medical billing field several years ago for Dr. Kathy Easterling for about two years before I decided to continue my education. I successfully obtained my B.S. degree and worked in Education for nine years. I am passionate about teaching and caring for people. I returned to the medical field once again at Mountain Medical Specialties in September 2013 as an administrative assistant. I get to perform a variety of tasks, including purchasing, accounting, and medical billing. We all work here as a team and patient care is always a top priority. It is a pleasure to work for two wonderful, caring, and brilliant physicians, Dr. Flick and Dr. Frederickson.


Diane McCallister 

Office Manager/Accounting



I am a lifelong resident of Rabun County. I still live in the Warwoman community where I grew up with my sister and four brothers. I have a lot of precious childhood memories, especially the picnics in the park at the Smokey Mountains.

Family is the most important thing in my life. I am married with 3 grown daughters, a step-son and seven beautiful grandchildren. I love gardening with my husband and spending time with my family.

My career in healthcare begun in 1986 when I became employed by Dr. Richard Turner at Woodridge Hospital. During that time I continued my education at Truett McConnell College along with courses related to healthcare financial management. I became a member of HFMA (Healthcare Financial Management Association and later achieved my goal in 1997 to become a CHFP (Certified Healthcare Financial Professional) specializing in patient financial services. While working as a healthcare consultant I took a position with Dr. Kathy Easterling as she began her family practice her in Clayton.

I have had the opportunity to work with many physicians over the years. I specialize in physician credentialing, practice management, patient billing and coding. I am a current member of AAPC (American Association of Professional Coders).

I have been employed with Dr. Flick at Mountain Medical Specialties since June 2013 and really enjoying working here. I love the friendly atmosphere with both the patients and all the staff. I feel we all work as a team to make sure the patients get the care they need.


Sherry Watkins

Office Assistant



I am a proud native of Rabun County. I have 3 sisters and 3 brothers. I have many nieces and nephews but no children of my own.

I worked in manufacturing until 2006 when Fruit of the Loom closed. I then attended North GA Technical College for Medical Receptionist. I was on the President's List. I worked at Mountain Lakes Medical Center for 7 years in the ER registration and in Medical Records.

I received a warm welcome to become a member of this family in October 2014 as an Office Assistant for claims and billing. Dr. Flick and Dr. Frederickson really take the time to listen, understand the patients' needs and provide great care with the help of all team members. I recently felt warmth of this family when I became sick. Dr. Flick and team members took great care of me. This family atmosphere will put your mind at rest and take care of you physically. I know that recently a nurse found out that our patient did not have wood for heat and she was calling someone at 7:30 a.m. to get him some even at her own expense if need be. She was making sure that he was taken care of and it made me very proud to work here.


Dr. Flick's Clinical Staff



Sandra Hunnicutt

Medical Assistant



I was born and raised in Rabun County. I grew up on Black Rock in the heart of Mountain City with my parents and sister. I have been married to my husband for 31 years and we have 3 children, 4 grandchildren, and 1 dog named Snickers.

In my free time, I enjoy spending time with my family. My grandbabies are my pride and joy! I enjoy cooking, baking, shopping and swimming in the summer.

My career in healthcare began 29 years ago, and I have enjoyed every minute of it since! I have always enjoyed taking care of others and hope that I am able to make a difference in someone’s life. I have performed many duties in the medical field such as nursing, billing, accounting, and office management. Dr. Flick gave me my first job in the medical field in 1990.

I feel honored to be working alongside Dr. Flick and the other members of his office staff. I feel that we all work as a team to ensure that patient care is our top priority.


Debbie Watkins

Medical Scribe



I was born and raised in Rabun County and grew up in a small community known as Tate City, which is actually in Towns County but you must go about seven miles on a single lane, dead end, dirt road that starts in Rabun and ends in Towns County. I am one of nine children. I am married and have two grown children of my own. I enjoy spending time with my animals, which consist of a Yorkie named Bentley and a miniature donkey named Jack. I also enjoy mowing the grass, deer hunting, fishing, camping, taking the pontoon to the lake, spending time with my family and friends and listening to frogs holler at night.

I consider myself to be a people person that likes to laugh and try to make others laugh. I enjoy helping others and hope that I can make a difference in someone's life.

I have worked in the medical field for about fifteen years. I started in the local hospital and worked there for several years and was then discovered by Dr. Kathy Easterling and worked at her facility which was known as Rabun Medical Center. I started as a receptionist then got a lot of on-the-job training which consists of Medical Assisting. I also did phlebotomy, which I enjoyed.

It's nice working in an office that has a caring physician and an awesome staff that he treats as his own family. I am hoping for this to be my last career move and at the end of every day I hope someone leaves with a smile on their face or a good feeling in their heart because one of us at Mountain Medical Specialties made a difference.


Wellness PEMF Therapy Staff


Arthur Cataldo


Arthur Cataldo, ABD, LMBT  

Frequency Therapist



Arthur has been a Missouri-licensed clinical psychologist, is a certified hypnotherapist, a professional member of the Association for Past Life Research and Therapies, a North Carolina and Georgia-licensed massage and bodywork therapist, and has been nationally certified in therapeutic massage and bodywork. He is also a teacher and practitioner of hands-on healing, a Traditional Reiki Master Teacher, a Karuna Reiki Master Teacher, and the discoverer and Master Teacher of the Amanohuna System of Energy Healing. Arthur directed the Center for Transformation on Sanibel Island, Florida where he taught intuitive development. He has presented seminars internationally, and has practiced and taught past life therapy and healing for over 30 years.

As a psychologist, I became acutely aware of the interdependence of the mind and body.  One can’t heal one without addressing the other.  My focus has shifted more and more to healing the body first to provide a solid foundation for emotional and spiritual development.  While working with hands-on modalities I also used my voice to tone or sing whatever sounds felt appropriate for that client at that time.  I was amazed how the body responds to sound and specific frequencies.  That was my introduction to specific frequency healing.  My training with Dr Carolyn McMakin in Frequency Specific Microcurrent deepened my understanding and appreciation for frequency healing.  I now get to see amazing results every day in our clinic with pulsed magnetic frequencies, pulsed plasma and pulsed light.
