“Caring for patients is a unique privilege. I often meet patients at their most vulnerable moments, and I want to earn their confidence by showing them the respect, professionalism, and expertise that I would want from a surgeon.”

Dr. Lauren Orr brings extensive experience in endocrine and general surgery. In 2019, Dr. Orr completed a fellowship in Endocrine Surgery at University of California, Los Angeles where she was trained in neck ultrasound, thyroid and parathyroid surgery, and minimally invasive adrenal surgery, including both transabdominal and retroperitoneal approaches.

Outside of work, Dr. Orr enjoys running, hiking, photography, and traveling.
