Benjamin J. Samelson-Jones, MD, PhD, is an attending physician in the Division of Hematology at Children's Hospital of Philadelphia. He is board certified in hematology/oncology and pediatrics. He specializes in treating children with bleeding or clotting disorders, sickle cell disease, and other blood disorders. His current research is focused on gene therapy and immune responses related to Hemophilia.
Dr. Samelson-Jones enjoys this specialty because of the ability to provide care on an ongoing basis throughout childhood. Those long-term relationships are rewarding for both doctor and patient and a key part of CHOP’s culture of care. “I want every family who comes to CHOP to leave feeling that their child received personalized, high-quality, holistic medical care,” said Dr. Samelson-Jones.
Dr. Samelson-Jones earned his medical degree as well as a PhD rom Albert Einstein College of Medicine, Bronx, New York. He continued his training with a residency in pediatrics at Children’s National Health System in Washington, DC and a fellowship in hematology/oncology at CHOP.
Dr. Samelson-Jones is excited about the advances being made in curative therapies for inherited blood disorders. His research is also focused in that area, including projects to investigate the molecular basis of coagulation and immune responses in hemophilia as well as a potential gene therapy for hemophilia.

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.
