Daniel Au MD

Dr. Au was drawn to urology in medical school when he recognized it as a field known for implementing cutting-edge science and technology to further the care of patients as well as being a field centered around quality-of-life issues. Dr. Au loves that as a surgeon, he can follow in this tradition and both deliver tangible solutions to his patients and maintain a continuity of care unique within surgical specialties.

Dr. Au specializes in benign prostatic hyperplasia (BPH) treatments and has advanced training in the latest techniques, including Holmium Laser Enucleation of the Prostate (HoLEP). He also has experience in minimally invasive and robotic surgery for benign and oncologic urologic conditions. He received his training at the University of Kansas, which is known for extensive training in urologic oncology, robotic surgery, and advanced laser BPH and stone surgery.

Dr. Au loves the outdoors and the many options that living in the Portland metro area affords to appreciate the natural beauty of the Pacific Northwest. Outside of work, Dr. Au enjoys cooking, travelling, photography, baseball, and exploring the mountains and forests of the Pacific Northwest.
