Endocrine Surgery
Endocrine surgery is a subspecialty of general surgery that focuses primarily on diseases of the thyroid, parathyroid and adrenal glands.

Advanced Endocrine Surgery
Emerson Health is home to the only fellowship-trained endocrine surgeon in the greater Concord area, where we offer surgical treatments for thyroid, parathyroid and adrenal gland disorders.
Additionally, Emerson Health is affiliated with Massachusetts General Hospital — giving you streamlined access to even more advanced endocrine surgery care.
Conditions We Treat
- Thyroid and parathyroid cancer
- Adrenal tumors
- Goiter (abnormal enlargement of the thyroid gland)
- Graves’ disease (an immune system disorder that results in overproduction of thyroid hormones, or hyperthyroidism)
- Hashimoto’s disease (also known as chronic lymphocytic thyroiditis, a condition in which the immune system attacks the thyroid, often leading to hypothyroidism, which is an underactive thyroid)
- Hyperparathyroidism (an abnormally high concentration of parathyroid hormone in the blood, resulting in weakening of the bones through loss of calcium
Our Services
Each patient undergoes a thorough evaluation and consultation to determine if surgery is the right treatment for them.
We provide the full range of diagnostic and treatment services for endocrine-related disorders in adults that require surgery. The surgical services we offer include both open and minimally invasive techniques for:
- Parathyroid surgery to remove one or all four parathyroid glands (parathyroidectomy).
- Thyroid surgery including thyroid lobectomy (removal of half the thyroid gland) and total thyroidectomy (removal of the entire thyroid gland).
