Summary

  • Dr. Samuel Rosenfeld is an orthopaedic surgeon specializing in pediatric orthopedics based in Mission Viejo, CA. He completed his medical degree at Pennsylvania State University College of Medicine in 1977, followed by an internship and residency in orthopaedic surgery at the University of California (Irvine). He furthered his expertise with a fellowship in pediatric orthopaedics at Rancho Los Amigos National Rehabilitation Center. Dr. Rosenfeld has extensive experience in sports medicine, muscular dystrophies, minimally invasive spine surgery, short stature and skeletal dysplasia, and neuromuscular scoliosis. He has contributed to notable publications, including research on sublaminar band fixation and orthopedic guidelines for spina bifida. Dr. Rosenfeld is recognized as a fellow by prestigious organizations such as the American Academy of Pediatrics and the American Orthopaedic Association, and has received several teaching awards.
    After 42 years, I am retiring from Pediatric Orthopaedic Specialists of Orange County and CHOC Children’s Health on May 31, 2025. I have been honored to enable children to reach their maximal abilities and enhance their lives. I have been fortunate to participate in this rewarding endeavor.
    I would not have been able to pursue my compassion and commitment to excellence without the love and support of my wife of 52 years. I want to acknowledge the sacrifices of my family to help me achieve my success.
    As I enter this next chapter in my life, I want to express my gratitude to all of my patients and families for their dedication and motivation for quality care. Without the cooperation and shared expectations of our families, our treatment goals would not be possible to secure.
