The Thyroid and Parathyroid Center Treatment Team
Our Surgeons
Our fellowship trained head and neck oncologic surgeons in the Department of Otolaryngology—Head and Neck are not only experienced in thyroid and parathyroid surgeries but are also experts in procedures related to surgical management of thyroid cancer, such as neck dissection, tracheal resection, examining the larynx, salivary gland dysfunction and voice rehabilitation.
Maisie L Shindo, M.D., F.A.C.S., Surgical Director

Dr. Maisie Shindo received her M.D. from The University of Southern California in 1984. She completed her residency training in Otolaryngology Head and Neck Surgery at The University of Southern California Los Angeles County Medical Center, and earned her Board Certification in 1989. Subsequently, she pursued fellowship training in Head and Neck Oncology at Northwestern University Hospital as well as a fellowship in Microvascular Reconstructive Surgery at Ohio State University. In 1991 she joined the faculty of the Department of Otolaryngology-Head and Neck Surgery at The University of Southern California, where she gained national recognition for her work in micro-vascular head and neck reconstruction. Dr. Shindo joined our department in 2008 as Professor and as the Director of the Thyroid and Parathyroid Center, providing a full range of consultative, diagnostic and therapeutic service dedicated to patients with thyroid and parathyroid disorders. She is also the director of Head & Neck Endocrine Surgery for the Department of Otolaryngology Head & Neck Surgery.
Dr. Shindo has special expertise in the multidisciplinary management of complex thyroid and parathyroid disease. She has performed pioneering work applying new strategies, including minimally invasive parathyroidectomy, performed under local anesthesia and minimally invasive video-assisted thyroidectomy, an adaptation of the established laparoscopic procedure which provides patients the benefits of a much smaller incision, thus better cosmetic results. Dr. Shindo’s microsurgical techniques, for which she completed advanced training, coupled with her precise operative skills offers the most sophisticated care available to our patients. Dr. Maisie Shindo, has been performing primarily endocrine surgery since 1991, and has dedicated her career to the management of thyroid and parathyroid diseases. Dr. Shindo has done well over 4,000 thyroid and parathyroid surgeries, and is nationally respected as one of the top endocrine surgeons in the United States.
Ryan Li, M.D.

Dr. Ryan Li completed a bachelor's degree in neuroscience at Brown University, followed by his M.D. at the University of Pittsburgh School of Medicine. He completed his surgical training in Otolaryngology-Head and Neck Surgery at Johns Hopkins Hospital. Dr. Li then completed a fellowship in Head and Neck Surgery-Microvascular Reconstructive Surgery at Stanford University. He is board-certified in Otolaryngology-Head and Neck Surgery.
Dr. Li enthusiastically joins the faculty at Oregon Health and Science University in the Department of Otolaryngology-Head and Neck Surgery. As a new member of the Thyroid and Parathyroid Center Team, he joins a collaborative mission to walk patients through personalized consultations and complete diagnostic evaluations. Following these evaluations, Dr. Li devotes his time to developing treatment plans with patients, and personally performs their surgery and postoperative care.
Dr. Li is proud to partner with Dr. Shindo as providers of the most advanced surgical techniques to treat thyroid and parathyroid conditions—techniques that provide the best cosmetic results, the most thorough control of disease, with the greatest regard for patient safety. Both Dr. Shindo and Dr. Li are highly experienced in minimally invasive parathyroidectomy, in which patients can undergo precise surgical treatment under local anesthesia and a calming brief sedation. In thyroid surgical research, the importance of receiving care at a high volume center has been shown essential to achieving the best results. Together Dr. Shindo and Dr. Li perform over 400 thyroid and parathyroid cases per year.
"We are dedicated not only to performing the best surgery for you, but also guiding you through the entire treatment experience with your well-being in mind, at all times."
