Dr Biggs helps people with difficult endocrine problems, particularly diabetes, diabetes during pregnancy, and thyroid diseases.

For diabetes, all approved treatment modalities are available, including dietary education, oral medications, GLP-1 therapy, insulin, insulin pumps, artificial pancreas systems, and continuous glucose sensors.

Dr. Biggs has had additional training in reading thyroid ultrasound, and thyroid nodule fine needle aspiration, and has been credentialed by the American College of Endocrinology with the Endocrine Certification in Neck Ultrasound (ECNU).  When necessary, fine needle aspirates are performed in our ultrasound suite which is usually more comfortable and lower cost than the hospital setting.

Dr. Biggs was one of the first physicians in the country to be board certified in the new specialty of Clinical Informatics in 2013. He is the Medical Director for the Amarillo Legacy Medical ACO, which works to improve healthcare in Amarillo by better communication and collaboration among providers, and use of informatics tools to improve health care delivery.  Dr. Biggs speaks at conferences nationwide on population health, and how Amarillo has successfully implemented tools to provide better health at lower cost.
