J. Pablo Abonia, MD



I’m an allergist who specializes in treating children with eosinophilic gastrointestinal disorders, eosinophilic esophagitis, eosinophilia, mast cell disorders and urticaria. My research focuses on finding the most effective therapies for patients with eosinophilic and mast cell disorders.

Seeing my father work as a pediatrician inspired me to follow in his footsteps and choose medicine as a profession. I completed my formal pediatric training at Children’s Hospital of Buffalo and my allergy and immunology training at Brigham and Women’s Hospital in Boston. These experiences provided the education, skills and resources that prepared me to help my patients as a member of the Cincinnati Center for Eosinophilic Disorders (CCED).

When I care for my patients, I always put them first, with the goal of identifying their problems and working to resolve them. I strive to improve control of their symptoms. In my research, I work toward long-term control of diseases related to eosinophilic disorders and mast cell disease. I’ve published a number of journal articles in my field, and I am involved in multicenter clinical trials for eosinophilic disorders.

I was previously the interim director of the Registry for Eosinophilic Disorders. I presented the Joseph E. Ghory, MD, Memorial Lectureship for the Ohio Society of Allergy, Asthma, and Immunology; the 15th Annual Dr. John M. Karibo Memorial Lectureship; and at other national meetings related to eosinophilic and mast cell disorders. I’m also proud to be named one of Cincinnati Magazine’s Top Doctors.

Outside of the hospital, I enjoy spending time with my wife and family.

MD: University of Buffalo, Buffalo, NY, 1997.

Certification: American Board of Pediatrics, 2001; American Board of Allergy and Immunology, 2003.
