Manoj Warrier, M.D.



Dr. Warrier practices at the Allergy, Asthma & Food Allergy Centers, specializing in the treatment of children and adults with allergies, asthma, and immune deficiencies. He sees patients at the South County Location at Gravois and 270, the West County (Chesterfield) location at Clarkson and Baxter, and in Swansea, Illinois. Prior to joining the practice in 2008, he was on faculty at the Cincinnati Children’s Hospital Medical Center in the Division of Allergy and Immunology, where he focused on basic science research and teaching.

Dr. Warrier earned his bachelor’s degree from Centre College in Danville, Kentucky with a double major in Biochemistry & Molecular Biology and Chemistry. He graduated with his medical degree from the University of Louisville School of Medicine. He completed a combined Internal Medicine-Pediatrics Residency at St. Louis University Health Sciences Center and Cardinal Glennon Children’s Medical Center, and Fellowship in Allergy and Immunology at St. Louis University.

Dr. Warrier is currently certified by the American Board of Allergy and Immunology. He has also passed certification exams from the American Board of Internal Medicine and the American Board of Pediatrics. He has been an invited speaker for American Academy of Allergy, Asthma & Immunology (AAAAI), the Missouri Association of Osteopathic Physicians and Surgeons, and other Continuing Medical Education meetings. He was twice been awarded the Outstanding Junior Faculty Pediatric Abstract Award presented by the American Academy of Pediatrics Section of Allergy and Immunology at the AAAAI.

He has coauthored several papers, including studies on food allergy -“The Prevalence, Severity, and Distribution of Childhood Food Allergy in the United States” published in Pediatrics in 2011 (the often quoted 1 in 13 children are affected by food allergies comes from this paper)  and “Parent Report of Physician Diagnosis in Pediatric Food Allergy” published in the Journal of Allergy and Clinical Immunology in 2012.  He is incredibly passionate about food allergies, since his older daughter has had multiple food allergies (peanut, tree nut, and chickpea) since infancy, but we are happy to report that his daughter has “graduated” from peanut OIT (oral immunotherapy)/desensitization and is currently on OIT for tree nuts.

He is actively involved in the training programs for Internal Medicine Residency at SSM St. Mary’s Health Center, Internal Medicine Residency at Mercy St. Louis, the Allergy & Immunology Fellowship at Saint Louis University, and Saint Louis University’s Physician Assistant Master of Medical Science. Dr. Warrier is also a Clinical Associate Professor in the Division of Allergy and Immunology at Saint Louis University.

In his free time, Dr. Warrier loves live music, sci-fi/fantasy novels, Star Wars, comics, hiking, backpacking, snowboarding, racket sports, the occasional glass of bourbon with good friends (he did grow up in Kentucky, after all), and spending time with his family.
