He joined CHOP Radiology in 2017 as an attending pediatric radiologist and Assistant Professor of Radiology. He is a member of the Center for Pediatric Clinical Effectiveness at CHOP with research emphasis in this field as it pertains to radiology. He is also a member of both the Section on Genitourinary Imaging and Section on Cardiovascular and Lymphatic Imaging.
Dr. Otero completed two consecutive fellowships in management at the Harvard Medical School in Boston. The first one was an Administration Fellowship at Gill Management and Hospital and the second one a Radiology Management fellowship at the Department of Radiology at Brigham and Women’s Hospital. He completed Diagnostic Radiology residency in 2013 at Tufts Medical Center, Tufts University Medical School in Boston. In 2014 he completed his pediatric radiology fellowship at Children’s Hospital of Philadelphia and then joined the Department of Diagnostic Imaging and Radiology at Children’s National Medical Center in Washington, D.C.
From 2002 to 2005, prior to his radiology career, Dr. Otero practiced medicine in Venezuela and as an emergency response physician with Doctors without Borders/Médecins Sans Frontières (MSF) in Liberia, Sudan, Angola, Pakistan and Yemen. He still serves as a teleradiologist for MSF.
Dr. Otero has continued his international outreach in pediatric radiology education and participated in educational missions to Haiti, Ghana and Ethiopia. He has served as the Rad-Aid International Pediatric Radiology Program Manager for Latin America and Africa and is a member of the CHOP Radiology RAD-AID chapter. Dr. Otero was recently appointed as the Director of Outreach for the World Federation of Pediatric Imaging (WFPI). Dr. Otero is a Global Health Scholar of the Center for Global Health (CGH), Perelman School of Medicine, and a Senior Fellow of the Leonard Davis Institute of Health Economics at the University of Pennsylvania.

Patient Experience Ratings
About the Patient Experience Rating System
The Patient Experience Rating is an average of all responses to the care provider related questions shown above from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
