Pediatric otolaryngologist Jonathan Walsh specializes in head and neck masses, thyroid disorders, vascular malformations, tracheostomy, tracheal stenosis, aerodigestive disorders, chronic ear disease (ear infections), sinus disease (sinusitis), hearing loss, ankyloglossia (tongue-tie), sleep apnea and laryngeal cleft, as well as the full spectrum of pediatric head and neck disorders. He offers minimally invasive endoscopic ear surgery and minimally invasive surgeries of the airway, ear and sinus. Dr. Walsh earned a medical degree from Virginia Commonwealth University School of Medicine and completed residency training in otolaryngology at University of Rochester Medical Center. He served two years of active-duty service as a major in the U.S. Army at Fort Gordon in Georgia, after which he completed fellowship training in pediatric otolaryngology at the University of North Carolina. His research interests are in novel imaging technology applications for head and neck disorders; outcomes and health care disparities; ankyloglossia and lip tie; head and neck masses; and airway imaging and modeling. Dr. Walsh is director of the Johns Hopkins pediatric aerodigestive team and surgical director of the pediatric thyroid team. Additionally, he is an active participant in the vascular anomalies team, fetal therapy multidisciplinary team and pediatric sarcoma tumor board. Dr. Walsh is also the residency program director for the Department of Otolaryngology-Head and Neck Surgery.

Nicholas Rowan is a sinus and skull base surgeon who helps patients with conditions such as deviated septum, nasal congestion, nasal obstruction, sinus pressure and chronic sinusitis, as well as complex issues like loss of smell, sinus cancers, cerebrospinal fluid (CSF) leaks and tumors that grow near the brain. He frequently performs nasal polyp surgery and endoscopic sinus procedures, using minimally invasive approaches to help patients recover quickly and breathe more easily. For tumors of the skull base or brain, he works closely with neurosurgeons and cancer specialists to deliver coordinated, comprehensive care. Dr. Rowan’s research is focused on improving patients’ quality of life and long-term outcomes after sinus and skull base surgery. A major part of his work involves studying the sense of smell — not just how to restore it, but how it reflects overall health. He explores how smell loss may be an early warning sign of unhealthy aging, frailty or cognitive decline. Through this work, he aims to better understand the biological link between the nose and brain, and what it can reveal about a person’s health trajectory. He works closely with biomedical engineers to develop novel diagnostic and therapeutic technologies, and he is the principal investigator of multiple ongoing clinical trials that are testing new treatments for chronic sinusitis and nasal polyps. A frequent speaker at national and international conferences, Dr. Rowan shares insights from his innovative research and surgical experience. He leads courses and delivers lectures on advanced sinus and skull base techniques, smell loss and the evolving science behind how nasal health connects to overall well-being.

Alan R. Cohen is the director of pediatric neurosurgery at Johns Hopkins Children’s Center in Baltimore, Maryland, and one of the top pediatric neurosurgeons in the country. His area of specialty is treating infants and children diagnosed with brain tumors. Dr. Cohen’s goal is to get his patients back to being a kid again. He has a patient-centered approach to caring for each of his patients, working closely with the child’s family at every stage of the decision-making process. Dr. Cohen sees patients in the neurosciences clinic located in the Levi Watkins, Jr., M.D., Outpatient Center. As the Carson-Spiro Professor of Pediatric Neurosurgery, Dr. Cohen is a leader in developing minimally invasive techniques to enhance the safety and efficacy of selected pediatric neurosurgical procedures. He serves as director of the Minimally Invasive Neurosurgery Laboratory at Johns Hopkins and directs the Minimally Invasive Neurosurgery Fellowship Program. His lab focuses on developing novel instruments and surgical approaches. He has authored more than 200 peer-reviewed journal articles and book chapters, and published two textbooks. He has given approximately 330 national and international presentations, and has been an invited visiting professor at 50 medical centers. He is past president of the Society of Neurological Surgeons, the American Society of Pediatric Neurosurgeons and the AANS/CNS Section on Pediatric Neurological Surgery. He is past vice president of the American Academy of Neurological Surgery, a past director of the American Board of Neurological Surgery and current director of the American Board of Pediatric Neurological Surgery.
