They help to treat a variety of endocrine disorders, including diabetes, thyroid disorders, and hypopituitarism following post traumatic head injury.

Dr. Linfoot’s distinguished career in medicine began in 1955 when he received his Bachelor of Medicine and Master’s degrees in Physiology and Pharmacology from the University of North Dakota.

For 20 years, Dr. Linfoot was a research associate and senior staff scientist at the Lawrence Berkeley Laboratory, where he directed the patient care and laboratory programs for patients undergoing heavy ion pituitary irradiation at the 184-inch synchrocyclotron. The pituitary irradiation program employed magnetically focused pituitary irradiation for patients with pituitary tumors, diabetic retinopathy, and metastatic breast cancer. Dr. Linfoot subsequently developed endocrine testing laboratories and treatment centers at Alta Bates Hospital in Berkeley and at Providence Hospital in Oakland, California before starting his private practice.

Dr. Linfoot is a member of the Endocrine Society, the American Association of Clinical Endocrinologists, and the American Diabetes Association.

Endocrinology is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones. Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose and determine the severity of or to treat a variety of diseases, including many types of cancers and other abnormalities within the body. As an endocrinologist and nuclear medicine specialist, Dr. Linfoot treats children and adults with pituitary, thyroid, adrenal and gonadal diseases, as well as with metabolic disorders e.g. diabetes and hyperlipidemia.
