Mary-Kay Davidson-Taylor, MS OTR/L

Director, Clincial Services


Mary-Kay earned her Masters Degree in Occupational Therapy in 1998 from Kirksville College of Osteopathic Medicine, Arizona School of Health Sciences. She has worked with children in Arlington County and Fairfax County Early Intervention Programs; private daycares, preschools, and elementary schools such as in Alexandria (Meeting House Cooperative Preschool, St. Paul's Preschool, Alexandria Country Day School, Grace Episcopal, St. Rita School, St. Mary School, Saint Stephens Saint Agnes School), Arlington (National Science Foundation Child Development Center), Fairfax County (Aquinas Montessori, Browne Academy, CIA daycare), and Washington, DC (Beauvoir:The National Cathedral Elementary School, St Patrick School); ARC of Caddo-Bossier Early Intervention School and Home Health Program; and Willis-Knighton Medical Center in Shreveport, LA.


Mary-Kay currently works with children in both her Kidz Therapy private practice (since 2004) and at Georgetown University Hospital (since 2010) in the outpatient pediatric occupational therapy clinic.

Mary-Kay has experience working with children birth to 21 years old. All children are unique despite similar diagnoses or presentations and are all seen as individuals and helped according to their own specific strengths and challenges. Children helped have challenges in sensory processing, fine, gross, oral motor/sensory, feeding, behavior, and/or visual motor/perception. Some children present with no specific diagnosis, but are struggling in school or with peer interaction. Some children have difficulty processing sensory input or modulating their own internal body rhythm. Mary-Kay has experience helping children with these presentations and other varied diagnoses such as prematurity, ADHD, Cerebral Palsy, Sensory Processing Disorder, Autism, Developmental Coordination Disorder, Downs Syndrome, Kabuki Syndrome, Ehlers-Danlos Syndrome, Pervasive Developmental Delay, Dyslexia, Pierre Robin Syndrome, Rett Syndrome, Aicardi Syndrome, Hemiplegia, in utero strokes, Hypotonia/Hypertonia, Dyspraxia, Feeding Difficulties, and others.
