She is a strong patient advocate and sets high standards of care, continually striving for improvement and meticulously planning surgeries to provide patients with the best possible outcomes.

Dr. Tseng is a native of Southern California, having grown up in Orange County, California. She attended medical school at the University of California, Davis. She completed her General Surgery residency training at Oregon Health and Science University and fellowship training in Clinical Immunotherapy at the National Cancer Institute and Complex General Surgical Oncology at University of Chicago. She pursued additional fellowship training in medical education and clinical medical ethics at the internationally renowned MacLean Center at University of Chicago.

Dr. Tseng has expertise in addressing cancers of the breast, skin, and soft tissue. As Medical Director of Breast Surgery at City of Hope Orange County, she is committed to offering patients a slate of innovative clinical trials. As a researcher, she has co-authored over 100 peer-reviewed publications, review articles, book chapters and abstracts, including studies in the Journal of Clinical Oncology, Annals of Surgery and Annals of Surgical Oncology.

Before joining City of Hope, Dr. Tseng was an Assistant Professor of Surgery at University of Chicago, where she was recognized with her department’s Excellence in Teaching Award. She serves on the editorial board of the Journal of Surgical Education and holds leadership and committee positions within the Society of Surgical Oncology, American Society of Clinical Oncology and American Society of Breast Surgeons.

Dr. Tseng is extremely happy to return to the place she considers home and serve the local community. Away from medicine, she loves spending time with family and friends. She enjoys exploring new restaurants, the local arts scene, and traveling. She likes to play tennis, hike, ski, and snowshoe and is learning the game of golf to keep up with her Orange County neighbors!
