Mari Groves is a Johns Hopkins pediatric neurosurgeon who cares for children with brain and spinal cord tumors (benign and cancerous), skeletal dysplasia, and spinal deformities such as neuromuscular and early scoliosis. She also sees patients diagnosed with Chiari malformations, spasticity and epilepsy. She specializes in treating patients with all types of spina bifida, including myelomeningocele. As part of the Johns Hopkins Center for Fetal Therapy, she is an expert in prenatal closure techniques such as minimally invasive fetoscopic repair of myelomeningocele (when the spina bifida defect is repaired before birth). Offering a transitional practice model of care, she follows patients diagnosed with spina bifida from birth to adulthood. Dr. Groves chose to pursue neurosurgery because it allows her to treat patients with complex conditions and help improve the quality of children’s lives. Her research interests focus on pediatric spinal disease and how surgical intervention can impact growth and neurological function during a child’s life. She is committed to building programs that support patients with congenital disorders as they age. Pediatric patients often age out of existing programs and have difficulty locating physicians and treating teams that understand their conditions. At Johns Hopkins, we have a unique ability to provide this type of comprehensive care. Dr. Groves earned her medical degree from the Vanderbilt University School of Medicine in 2007. She completed residency training in 2014 at The Johns Hopkins Hospital, where she remained for a neurosurgery fellowship, which she finished in 2015. She also completed a spinal deformity fellowship at Shriners Hospitals for Children in Philadelphia.

Dr. Damon S. Cooney is an associate professor of plastic and reconstructive surgery at the Johns Hopkins University School of Medicine. Dr. Cooney performs all types of general plastic surgery but specializes in microvascular reconstruction (free flaps). A particular focus of his clinical practice is improving the functional and aesthetic results of head and neck reconstruction.He completed additional fellowship training at the University of Pittsburgh to become an expert in microsurgical techniques for reconstructing the extremities, trunk, breast, and head and neck following traumatic and/or oncological defects. Dr. Cooney earned a Ph.D. from Ohio State University Department of Molecular, Cellular and Development Biology.Dr. Cooney’s clinical and basic research focus is composite tissue allotransplantation (CTA). He is a member of the Composite Tissue Allotransplantation team at Johns Hopkins and helps conduct human hand and face transplantation trials. His laboratory work includes engineering human tissues for reconstructive purposes, nerve regeneration, microsurgical education and inducing tolerance in order to reduce or eliminate the need for systemic immunosuppression in transplantation patients.Dr. Cooney has published numerous peer-reviewed articles and book chapters in addition to being a reviewer for plastic surgery journals. He is a founding member of the American Society for Reconstructive Transplantation.
