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, MD, FACS, Surgical Director

Maisie Shindo, MD

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.

Our Endocrinologists

Our endocrinologists provide a full range of diagnosis and treatment services to patients with thyroid and parathyroid disorders.  

Dana Madison, MD, PhD, Medical Director

Dana Madison, MD, PhD

Dr Madison graduated with a MD and PhD (Biochemistry and Molecular Biology) from  the University of Connecticut in 1998. He completed a residency in Internal  Medicine at OHSU in 2000 and an Endocrinology fellowship at OHSU in 2003. Dr  Madison is board certified in Internal Medicine and Endocrinology. Dr Madison serves as Co-Director of the Thyroid and Parathyroid Program, consulting with patients and providing a full range of diagnosis and treatment services to patients with thyroid and parathyroid disorders. His research interests are in molecular mechanisms of tumor metastasis and transcription.

Mary H Samuels, MD

Mary H Samuels, MD
Dr. Samuels` clinical and research interests are in pituitary disease and thyroid. After receiving her medical degree in 1983 at Harvard Medical School in Boston, Dr. Samuels completed both her residency and fellowship at the University of Colorado in Denver.

Kathryn G Schuff, MD

Kathryn G Schuff, MD

Dr. Schuff has clinical and research interests in pituitary and thyroid neoplasms and hormone regulation. She has conducted clinical research projects designed to improve diagnostic procedures as well as treatment modalities for patients with pituitary tumors including Cushing's syndrome, pituitary hormone deficiencies and thyroid cancer. She helps direct the Thyroid Tumor Clinic, a multidisciplinary clinic staffed by endocrinologists and otolaryngologists with close interaction with OHSU's head and neck radiologist and nuclear medicine staff to provide comprehensive, coordinated care for patients with thyroid and parathyroid disease.


Our Care Team

Management of patients at the Thyroid and Parathyroid Center is also complemented by members of other specialties, such as radiology, nuclear medicine, medical oncology, pathology, laryngologists, and radiation oncology.  

Matthew H Taylor, MD

Matthew Taylor, MD
Matthew H. Taylor, MD is a medical oncologist who dedicates his clinical practice and research to treating advanced thyroid cancer. Dr. Taylor specializes in Phase I clinical trials for patients with advanced cancers. He has a particular interest in thyroid cancers. In addition to his clinical research, Dr. Taylor studies cancer cells and patients tumors in his laboratory. Dr. Taylor and his wife Jessica, are the proud parents of four daughters. When he is not at the hospital, he is at soccer games, piano recitals, ballet and dance performances, and school plays. When there's time, he enjoys cycling, golf, and oddly enough – yard work.


The OHSU Genetics team evaluates individuals with hereditary cancers/syndromes that also involve thyroid and parathyroid tumors, such as multiple endocrine neoplasias and Cowden disease. Our pathologists have dedicated expertise in thyroid and parathyroid diseases. In addition, we offer personalized treatment based on genomic testing using tumor molecular markers. This includes analysis of molecular markers on thyroid needle biopsy to assess specific cancer risk in individual tumors, which can avoid surgery for some patients. Our ultrasonographers and surgeons are highly experienced in ultrasound for thyroid and parathyroid disease and can perform ultrasound guided needle biopsies (FNA). Our radiologists are also experts in reading CT scans, MRIs, PET scans and other nuclear medicine studies. The Center has an integrated approach to administration of radioactive iodine for thyroid cancer.
