At The Children's Clinic of Conway & Greenbrier we have three full-time pediatricians and six APRNs (advanced practice registered nurses or APNs for short.)  Our pediatricians are certified by the American Board of Pediatrics and are all three are Fellows of the American Academy of Pediatrics. We strive to follow the guidelines and recommendations of the American Academy of Pediatrics. We are fortunate that all of our APNs  dedicate their professional time exclusively to the care of children and adolescents; three of our APNs have been with our practice for more than ten years.


 Dawn “Pebble” Sutherland, M.D.

Dr. Sutherland has been a part of The Children's Clinic of Conway and Greenbrier (formerly Conway Children's Clinic) since 1992.  She is a graduate of Hendrix College and Vanderbilt University School of Medicine and completed her residency in Pediatrics at Vanderbilt University Medical Center.  The choice to enter medicine suited her interests in health, science, and teaching (in this case, teaching patients and their families); Pediatrics was a natural choice fulfilling her desire to work with children.

Dr. Sutherland and her husband David raised three children together and enjoy more free time now that their children are grown.  She is a member of First United Methodist Church and helps keep the food pantry stocked for visitors from the community; for many years she taught Created by God, a human sexuality course for preteens.  She previously served on the board of Milestones (formerly Faulkner County Day School) and is a regular speaker in the mentoring program for teen parents at Conway Cradle Care.  She and her husband travel when possible and enjoy trips to visit their children who are scattered in nearby states.

Kelly Staley, M.D.

Dr. Staley joined our practice in 2000 following her residency at The University of Arkansas for Medical Sciences and Arkansas Children’s Hospital. A native of Cabot, Arkansas, she received her Bachelor of Science in Microbiology from the University of Arkansas and her medical degree from the University of Arkansas for Medical Sciences. Dr. Staley always found science interesting and was drawn to Pediatrics because she wanted a way to positively impact the lives of children. She loves watching children and families grow. Dr. Staley enjoys working in our Greenbrier office when she is not covering nursery rounds and on-call responsibilities in Conway.

A native of Cabot, Arkansas, Dr. Staley was happy to settle near her family. She and her husband Tony have two grown children and enjoy travel together. She attends OneChurch and is involved in many outreach programs such as City in the Dark at Halloween.

Chris Killingsworth, M.D.

Dr. Killingsworth joined our practice in July 2012 as we celebrated our 25th anniversary – with an event in Laurel Park when the temperature was 103 degrees. As an undergraduate at The University of Arkansas at Little Rock Dr. Killingsworth started out as a computer science major but then realized he would enjoy helping and interacting with people more directly in the practice of medicine. After graduating from The University of Arkansas for Medical Sciences he completed his residency in Pediatrics at UAMS and Arkansas Children’s Hospital. In Pediatrics he enjoys solving health problems with families and providing reassurance when that is needed. Our patients love Dr. Killingsworth and his computer science brain comes in handy in our practice.

Having completed all of his education in his hometown of Little Rock, Dr. Killingsworth and his wife chose to reside in Conway in order to stay close to family; they enjoy the small town feel along with some big town amenities, 'the best of both worlds'. Dr. Killingsworth and his wife Katy have two young daughters. He enjoys reading, biking, hiking, and disc golf as well as walks with their two greyhounds and care for their backyard chickens.

Misty had great appreciation for the nurses and doctors who explained her father’s condition and treatment in ways she could understand. She began to see herself as one called to care for patients and their families. Now Misty loves “growing up with” her young patients and their families, from meeting newborns and their sometimes anxious parents to helping teens overcome some of the challenges of adolescence.
