Dalton joined HealthTree in 2024 as the CLL and MF Education Manager. He is passionate about helping patients gain a better understanding of their health and treatment and sees it as a way to help empower individuals and their families who are affected by these diseases. Prior to joining HealthTree Dalton earned a Master’s Degree in Oncological Sciences while studying various different blood cancers. When not interacting with patients he is an avid snowboarder and hiker.

Dr. Rafael Bejar, MD, PhD, is board certified in internal medicine, medical oncology, and hematology, with a special interest in hematologic malignancies (blood cancers). He specializes in the care of patients with myelodysplastic syndromes (MDS) and related blood disorders. Dr. Bejar has established a MDS Center of Excellence at UC San Diego Health focused on providing the best diagnostic tools, supportive care, clinical trials, and medical expertise in one center. Dr. Bejar is a physician-scientist who, in addition to caring for patients, runs a research laboratory dedicated to the study of MDS. His focus is to discover disease features that can be used to personalize the care of patients with MDS. He has published key papers in the New England Journal and the Journal of Clinical Oncology examining the genetic changes that drive the development of MDS. His efforts have led to the development of clinic tests for mutations that help predict prognosis and individualize treatment options for patients. Current research involves investigating how acquired mutations in MDS patients are associated with their response to treatment with drugs like azacitidine and decitabine, in hopes to discover genes that physicians can test for mutations in order to select the best treatment options. These studies should also provide insight into the mechanisms of drug resistance and how to overcome them.
