Welcome Dr. James J. Lieu, DO: The Newest Addition to Our Team

At our practice, we don’t just bring on new physicians—we welcome them into a family. That’s why we are thrilled to introduce Dr. James J. Lieu, DO, a highly skilled and compassionate physiatrist with specialized training in sports medicine and interventional pain management/spine care. Dr. Lieu is not just a new addition; he has been mentored and guided by two of our own, Dr. Moradian and Dr. Vartanian, since his residency days at Casa Colina in Pomona, CA. His journey with us has been years in the making, making his arrival feel more like a homecoming.


A Strong Educational Foundation & Advanced Training

Dr. Lieu brings a wealth of knowledge and expertise in the comprehensive care of spine, joint, muscle, tendon, ligament, and peripheral nerve disorders. His educational background includes:

  • Fellowship in Interventional Pain Management/Spine Care & Sports Medicine – Orthopaedic & Spine Specialists/OSS Health
  • Residency in Physical Medicine and Rehabilitation – Casa Colina Hospital and Centers for Healthcare, Pomona, CA
  • Internship in Transitional Year – Larkin Community Hospital
  • Doctor of Osteopathic Medicine – Alabama College of Osteopathic Medicine
  • Master’s of Arts in Kinesiology – University of Maryland
  • Bachelor’s in Public Health – Johns Hopkins University


Dr. Lieu is board-certified in Physical Medicine and Rehabilitation (PM&R) and is proficient in performing advanced, minimally invasive procedures under fluoroscopic and ultrasound guidance for the spine. He also specializes in electrodiagnostic testing (EMG/NCS) for the diagnosis of muscle and nerve disorders. His areas of interest include regenerative medicine, neuromuscular ultrasound, and medical education.


A Physician Who Feels Like Family

Dr. Lieu’s relationship with our practice goes far beyond his impressive credentials. Having trained with Dr. Moradian and Dr. Vartanian, he has been shaped by the same commitment to excellence, patient-centered care, and innovative treatments that define our philosophy. His integration into our team is seamless because he already embodies the values and expertise we stand for.


When Dr. Lieu is not seeing patients, he enjoys spending time with his family, traveling, trying new restaurants, and watching sports. Born in Denver, Colorado, he remains a devoted fan of his hometown sports teams.


We are honored to have Dr. Lieu on board and excited for our patients to experience the care, dedication, and skill he brings to our practice. Join us in welcoming him and be on the lookout for new advancements and compassionate treatments led by our growing team!
