About Us


Palmetto Aesthetic Medicine offers a wide range of non-surgical cosmetic services in a comfortable, relaxing environment.  Our goal is to help you understand all of the treatment options available for making you look your best at any age.

Dr. Billie Jean Waddell and Dr. Randall Colby met in 1992 while attending the University of South Carolina School of Medicine and were married one year later.  They completed a Pediatric Residency together and both practiced as private pediatricians for numerous years.  They are both retired from Pediatrics and are now dedicated exclusively to the field of Aesthetic Medicine.  They have combined forces to bring you one of Columbia's exclusive medical practices solely dedicated to the use of Botox Cosmetic and Facial Fillers.  Because they spend every day injecting, their time is not divided between other services.  They feel that when your doctor is focused on one specific area, they are able to become the best at what they do.  Dr. Waddell and Dr. Colby personally perform all consultations and procedures in their practice.

Dr. Waddell and Dr. Colby have been married for 27 years and have two teenage daughters and a Great Dane named Moose.  They enjoy water sports, boating, traveling and are active members of their church.
