      Ryan J. Chuang, MD, MPhil

      Urologist

      Dr. Chuang obtained his medical degree from the School of Medicine at UCLA prior to completing his urology residency training at UCLA. During his residency, he performed research with Dr. Leonard Marks on focal therapies such as HIFU and cryoablation for the application of treatment of prostate cancer. After residency, Dr. Chuang completed a Robotics and Urologic Oncology Fellowship at Swedish Medical Center under the tutelage of world-renowned robotic surgery expert Dr. James Porter.
