Dr. Charles A. Popkin specializes in pediatric, adolescent, and collegiate sports medicine, with an emphasis on the operative and non-operative treatment of complex knee disorders. His specific clinical interests involve primary and revision ACL reconstruction, patellar instability, cartilage injuries and disorders, meniscal tears, and recalcitrant patellar tendinopathy. With dual fellowships in Pediatric Orthopedics and Sports Medicine, Dr. Popkin has dedicated his career to the comprehensive treatment and prevention of injury in developing athletes. He has a particular interest in the management of ice hockey injuries, serving as a team physician for USA Hockey, and on the USA Hockey National Safety and Protective Equipment Committee. Dr. Popkin is also the head team physician for: Fordham University, Mercy College, and the Hackley School in Tarrytown. In addition to his academic practice, Dr. Popkin conducts research on ACL injury prevention, ACL reconstruction techniques in the pediatric athlete, overuse injuries in youth sports, refractory patellar tendonitis, and shoulder instability in ice hockey. He pens a monthly "Ask Dr. Hockey" column for USA Hockey Magazine. Dr. Popkin lives in Westchester and enjoys spending time with his wife and two sons.

Joshua Milner is a leader in the field of discovery and immunopathogenesis of genetic diseases that lead to allergic symptoms. Among the disorders he has described and/or found major mechanistic insight are PLAID—an immune disorder that leads to lifelong cold urticaria, the glycosylation disorder PGM3 deficiency, ERBIN mutation, CARD11 dominant negative mutations, STAT3 gain-of-function, Hereditary Alpha Tryptasemia Syndrome, IL-6 receptor deficiency, and others. Dr. Milner graduated with an SB in biology from the Massachusetts Institute of Technology (MIT) in 1995 and an MD with distinction in immunology from the Albert Einstein College of Medicine. He completed his residency in pediatrics at the Children’s National Medical Center in Washington, DC, and, as the recipient of the Pediatric Scientist Development Program Fellowship, did his fellowship in allergy and immunology at NIAID. He completed a postdoctoral fellowship with Dr. William E. Paul, NIAID, examining issues of mouse T-cell receptor repertoires before beginning as an investigator in the Laboratory of Allergic Diseases in the NIAID, where he was eventually named chief. Dr. Milner's vision is to establish how genetic variation can help inform diagnosis and care of all patients with allergic disease—rare and common, severe and mild. This is achieved by performing genetic sequencing on samples from patients with allergic disease of all sorts, as well as performing functional studies on the same patient samples, which together help point to specific immune pathways that may be fundamentally causing disease. This comprehensive analysis, when performed in larger populations, will help personalize medicine so that patients can be better categorized for targeted care. Furthermore, this type of research and care requires a coordinated and comprehensive interdisciplinary approach, taking advantage of the expertise across the department of pediatrics and at multiple outpatient sites.
