As a general pediatric otolaryngologist, I focus on diseases of the ear, nose and throat (ENT) in children and adolescents. My clinical and surgical practices involve the evaluation and treatment of general pediatric diseases, such as recurrent and chronic ear infections, hearing loss, sinus disease, sleep apnea, swallowing difficulties and airway disease. I strive to provide comprehensive, compassionate and patient- and family-centered care.

I was first inspired to pursue pediatric otolaryngology by my brother, a remarkable young man with Down syndrome. Throughout his childhood, he was treated for chronic sinus disease, hearing loss and sleep apnea. He encountered many specialists who were excellent clinicians and surgeons. But he ultimately returned to those who understood his disability well and embraced the unique challenges that it encompassed. In these specialists, he found exceptional advocates for his health, and in these caring physicians, I found role models for a career in otolaryngology.

For this reason, I have a particular interest in the evaluation and treatment of otolaryngologic disease in children and adolescents with Down syndrome as well. I participate in a multidisciplinary clinic for children and adolescents with this condition. This clinic coordinates with the Thomas Center for Down Syndrome at Cincinnati Children’s.

I am a member of the Gold Humanism Honor Society, and I was awarded the Pediatric Otolaryngology Fellowship Research Award for work related to the evaluation of sleep apnea in children with Down syndrome. I am currently completing the Quality Scholars Program through the James M. Anderson Center for Health Systems Excellence at Cincinnati Children’s.

My research interests broadly cover ear, nose and throat disease in patients with Down syndrome. Currently, I’m investigating hearing loss and sinus disease in children and adolescents with Down syndrome in particular. I also have an interest in quality improvement, especially as it relates to improving healthcare systems.

When I’m not at work, I enjoy spending time with my wife and two daughters, working in the yard and learning to play the banjo.
