Ronald Davis, MD, FAAN
Child Neurology MD
Board-Certified in Pediatrics, Pediatric Neurology, and Epilepsy
Pediatric Neurologist & Epilepsy Specialist – Orlando, FL
For more than 30 years, Dr. Ronald Davis has dedicated his career to helping children and families living with neurological and seizure disorders. A board-certified pediatric neurologist and epilepsy specialist, Dr. Davis brings both exceptional expertise and genuine compassion to his patients at his private practice in Orlando, Florida. He is honored to have been selected as a “Best Doctor” in Orlando for more than 15 years running.
Dr. Davis received his medical degree from the Brody School of Medicine at East Carolina University and completed his fellowship in Child Neurology at Children’s Hospital Boston, followed by advanced training and an academic appointment at Harvard University, where he served as an assistant professor. A U.S. Army veteran, Dr. Davis served with honor for 10 years before transitioning fully to medicine.
Dr. Davis previously served as Co-Director of Pediatric Epilepsy at the Level 4 Epilepsy Center at Orlando Health Arnold Palmer Hospital for Children and as Medical Director of the Muscular Dystrophy Orlando Clinic. His clinical interests include epilepsy, Tourette syndrome, movement disorders, and pediatric headaches, with a focus on delivering cutting-edge care in a personalized, family-centered environment.
Recognizing the fear and uncertainty that can come with epilepsy, Dr. Davis founded one of the few Long-Term Monitoring (LTM) Centers outside of a hospital setting, designed specifically for children. With five dedicated beds and continuous EEG monitoring, the center offers a calmer, more comfortable alternative to hospital-based testing—helping families get answers and treatment plans in a less intimidating space.
Dr. Davis also established a clinical research program within his practice to ensure that families have access to the newest therapies through clinical trials—bringing the innovation of an academic center into the comfort and familiarity of a private practice setting.
For Dr. Davis, medicine has always been about connection—learning each child’s story, partnering with families, and striving every day to help kids thrive beyond their diagnosis. After decades in practice, Dr. Davis still finds it “heart-wrenching” to see a child struggling with seizures—but he’s just as driven today as when he began to make a lasting difference in their lives. “We focus on how we can get a patient’s epileptic seizures under control. It’s about giving every child a chance at a normal life—and helping families regain a sense of peace and control.”
Outside the clinic, Dr. Davis enjoys time on his cattle ranch, where he finds balance and peace working the land and caring for his animals. He also loves international travel and cherishes time with his wife and three daughters.
