About ACT

The Academy of Clinical Thyroidologists (ACT) was founded in May 2005 at the annual meeting of the Association of Clinical Endocrinologists (AACE) in Washington DC. The Academy of Clinical Thyroidologists is a professional society consisting of thyroid specialists in North American, Eurpoe, and Latin America who practice clinical Thyroidology. The Academy enourages skill development in diagnostic and interventional ultrasound, nuclear thyroidology, and cytopathology to promote excellence in clinical practice and optimal outcomes for patients.

Our Current Officers:
John Woody Sistrunk, M.D.

In 2001, he returned home to Jackson, Mississippi to start practice. In 2007 Dr. Sistrunk started Jackson Thyroid & Endocrine Clinic and sees patients on a daily basis. His practice encompasses a full service thyroid clinic including an on-site CLIA certified lab, an AIUM accredited thyroid ultrasound/FNA facility, thyroid cytology, and an ICANL accredited thyroid nuclear medicine hot lab. As an adjunctive clinical faculty member of the University of Mississippi, School of Medicine, he works with endocrinology fellows and internal medicine residents teaching both thyroid ultrasound and nuclear medicine. Serving as program chair, Dr. Sistrunk presents at the American Association of Clinical Endocrinologists (AACE) Nuclear Medicine Course. In addition, Dr. Sistrunk has served on the faculty of the AACE Endocrine University since 2002. He has been the Vice Chair for the American College of Endocrinology Neck Ultrasound Council.

Our Goals

The Academy of Clinical Thyroidologists promotes clinical expertise through a single field approach to endocrinology. Our members practice 50-100% clinical Thyroidology. ACT encourages excellence in practice and skill development in diagnostic and interventional ultrasound, nuclear Thyroidology, and cytopathology as a basic core of activities in order to practice at the highest performance level and achieve the best outcomes for patients.

Specific goals include:

  • To promote the certification of endocrinologists in diagnostic ultrasound and UG-FNA (ECNU Program), and nuclear Thyroidology.
  • To encourage endocrinologists to develop the skills needed to practice clinical Thyroidology exclusively.
  • To meet at least annually for a clinically-oriented program providing education and new information to ACT members in the field of clinical Thyroidology; and, preferentially in conjunction with annual meetings of the American Thyroid Association and the American Association of Clinical Endocrinologists which represent organizations directly related to thyroid diseases and clinical practice.
  • To foster relationships and liaison with all endocrine related organizations.
  • To encourage ACT member physicians to acquire knowledge in thyroid cytopathology, through workshops for clinical Thyroidologists.
  • To provide various “hands on” programs for our members via a preceptorship model where Thyroidologists can learn standard or new procedures.
  • To provide a members only e-mail network to discuss issues important to their practice and a venue for presentation, consultation and management of unusual or problematic thyroid disorders.
