About Our Surgeons

Gary Clayman, MD, FACS, FACE

Dr. Gary Clayman is one of the most experienced thyroid surgeons and arguably the most experienced thyroid cancer surgeon in the world. Dr. Clayman is a fellow of the American College of Surgeons and the American Head and Neck Society. For the past 30 years, Dr. Clayman was the leading head and neck thyroid surgeon at the University of Texas M.D. Anderson Cancer Center where he served as the Distinguished Chair of Head and Neck Surgery and the Chief of Head and Neck Endocrine Surgery since 2003. Dr. Clayman has limited his practice to thyroid and thyroid cancer surgery for more than 26 years.

Dr. Clayman has performed more than six hundred thyroid cancer operations per year for over twenty-six years among patients ranging from 6 months to 100+ years of age. Nearly half of Dr. Clayman’s patients have undergone failed initial surgery for their thyroid cancer by another surgeon or have recurrent, persistent, or aggressive thyroid cancer. Over the past four years, Dr. Clayman has performed over 800 thyroid operations per year. If it pertains to thyroid surgery or thyroid cancer, there is likely nothing that he hasn’t seen. Dr. Clayman has also written the Atlas of Head and Neck Surgery which is used by residents and fellows across the globe in their endocrine surgery training. What patients say about their surgeons is also important. See our reviews and 5 star ratings on Healthgrades as well as our many reviews on Google. Dr. Clayman and our surgeons at the Clayman Thyroid Center are very high volume surgeons. All that we do is thyroid surgery at a level of safety and quality that is without competitors. Many describe "high volume surgeons" as more than 100 operations per year. Although we care for our patients so that they feel like they are our only patients, Dr. Clayman cares for more than this "high volume" classification in almost every month, not in one year. Volume in thyroid surgery predicts lack of complications in thyroid surgery and cure of thyroid cancer, not achieved by lower volume surgeons. To our knowledge, no other thyroid surgeons in the United States have similar experience.

Dr. Clayman left the University of Texas M. D. Anderson Cancer Center in the fall of 2016 to form the Clayman Thyroid Center in Tampa, Florida. Dr Clayman now serves as the Director of Thyroid Institute at The Hospital for Endocrine Surgery where the Clayman Thyroid Center and Scarless Thyroid Center are both found. The Hospital for Endocrine Surgery also includes the Norman Parathyroid Center -- the world's number one center for parathyroid surgery, and The Carling Adrenal Center, the world's number one center for adrenal surgery. Dr Clayman has helped establish the first interdisciplinary institute dedicated solely to the evaluation and surgical management of thyroid cancer and thyroid diseases.

Dr Clayman is a member of more than 22 prestigious medical societies including the American Association of Endocrine Surgeons, Fellow of the American College of Surgeons, American Head and Neck Society, American Thyroid Association, American Association of Clinical Endocrinology, American Society of Clinical Oncology, International Association of Endocrine Surgeons, American Association for Cancer Research, American Academy of Otolaryngology and Head and Neck Surgery, and the Alpha Omega Alpha medical honor society. Dr. Clayman has received some 35 honors and awards over his career. He has been named to America’s Top Doctors for 19 consecutive years and Best Doctors in America for 18 consecutive years. For his entire career, he has been extensively funded through the National Cancer Institute and National Institute of Health (NIH) in his pursuit of a greater understanding of the genetic events that regulate thyroid cancers. He has 5 current patents and has published more than 217 peer reviewed publications. He has published 35 books chapters and books. His book, The Atlas of Head and Neck Surgery, published in 2011, is considered the standard in training of resident and fellows in head and neck endocrine surgery. Dr. Clayman serves on the editorial board of 8 scholarly journals. A full copy of Dr Clayman's curriculum vitae (resume) is available here.

Dr. Clayman has lectured nationally and internationally on the topic of surgical management of thyroid cancer from minimally invasive to aggressive thyroid cancer and the evaluation and management of recurrent or persistent thyroid cancer. He has been invited to speak at the American College of Surgeons, American Thyroid Association, American Head and Neck Society, and the American Association of Clinical Endocrinologists on many occasions. He developed and maintained the course in Current Concepts in Thyroid and Parathyroid Disease since 2003 which is attended nationally by surgeons and endocrinologists, alike. Dr. Clayman has never had a malpractice claim in his entire career. Dr. Clayman is married to his wife, Miky and has three incredible children ages 25, 19, and 10.

Rafael Toro-Serra, MD, FACS

Dr. Rafael O. Toro-Serra, MD, is a distinguished head and neck surgical oncologist who is one of the highest-volume thyroid surgeons in the US for the past 10 years. Dr Toro-Serra joined the Clayman Thyroid Center at the Hospital for Endocrine Surgery in 2023 from Orlando Health where he was Chief of Endocrine Surgery for the past 8 years.

Dr. Torro Sera has been part of our team in the past and trained in thyroid/thyroid cancer and parathyroid surgery with us. He performed his endocrine and thyroid cancer fellowship at MD Anderson under the mentorship of Dr. Gary Clayman prior to Dr. Clayman coming to the Hospital for Endocrine Surgery. After 2 years with Dr Clayman, Rafael came to Tampa where he joined Dr Jim Norman of the Norman Parathyroid Center. After 2.5 years with Dr Norman, Rafael went to Orlando Health to start their thyroid cancer and parathyroid center, becoming one of the highest-volume endocrine surgeons in the country. After 8 years in Orlando, Rafael was recruited back to Tampa to join our prestigious staff.

He is married and has 3 children in high school.

Thyroid Surgery - The best approach

This team approach of two highly experience thyroid surgeons in every operation is a tremendous patient benefit. Our least experienced thyroid surgeon in any operation has performed at least three thousand thyroid operations. In thyroid surgery, experience means everything. Your least experienced thyroid surgeon in your operation in our Center, is still one of the most experienced thyroid surgeons in the world!

It is estimated that nearly 250,000 patients per year undergo some type of thyroid operation annually in the United States. Unfortunately, almost 90% of these operations are performed by surgeons that perform 10 or less thyroid surgery operations per year. This is a truly terrifying statistic. The critical nerves of the voice box that control sensation and movement of the vocal cords must be identified and preserved in every thyroid operation. In addition, the parathyroid glands that control calcium in the body, must also be identified and spared. Although many different surgeons have been “trained” in thyroid surgery, volume of experience is everything. Never consider any thyroid surgery a “simple” or “easy” surgery. The concept that a thyroid operation is a “minor” surgery is erroneous. Thyroid surgery is most frequently small and minimally invasive, but that does not mean it is minor.

Thyroid surgery is an art form! All of the critical structures identified and spared in thyroid operations include the jugular vein, carotid artery, recurrent laryngeal nerve, external branch of the superior laryngeal nerve, and the upper and lower parathyroid glands.

Editors note: Patients have to ask the right questions and be their own best advocate. Nearly 50% of patients with thyroid cancer will never know they have a thyroid cancer until they have undergone their first thyroid operation (and often times the wrong operation). Meaning, many patients undergoing thyroid surgery for presumed benign disease, in fact have thyroid cancer but don't know it until they receive their pathology report from their first operation and that is the first time they see the diagnosis of thyroid cancer. Even more pointing, Hundahl et al. published in Cancer, 1998, 11% of patients with known thyroid cancer continued to have thyroid cancer found in their neck following their initial thyroid cancer operation.
