He has presented at numerous national and international meetings and has received grants and awards from the American Thyroid Association, American Association of Clinical Endocrinologists, Montreal General Hospital Foundation, Cedars Cancer Institute and has been the recipient of the Henry R. Shibata Research Traveling Fellowship Award.

Dr. Mitmaker’s clinical interests involve taking care of patients with endocrine surgical diseases of the thyroid, parathyroid and adrenal glands. He routinely performs surgery to treat benign and malignant tumors of these glands or to treat excess hormone secretion from them. He treats a variety of common and rare endocrine conditions associated with the thyroid (i.e. thyroid nodules and goiters, thyroid cancer, Graves’ disease), the parathyroid (primary hyperparathyroidism, 2° hyperparathyroidism, 3° hyperparathyroidism, and parathyroid cancer) and the adrenal glands (pheochromocytoma, Cushing’s syndrome, hyperaldosteronism, adrenocortical cancer, adrenal metastases and adrenal incidentalomas). Whenever possible, minimally invasive surgical techniques are employed.


A list of commonly treated conditions:

Thyroid Disorders:
– Thyroid nodules, cysts and goiters
– Thyroid cancer (papillary, follicular, medullary, anaplastic)
– Recurrent or advanced thyroid cancer
– Hyperthyroidism (eg. Graves’ disease, toxic/hyperfunctioning nodules)
– Thyroglossal duct cysts
– Ultrasound guided fine needle aspiration biopsy of thyroid nodules

Parathyroid Disorders:
– Hyperparathyroidism (primary, secondary, tertiary)
– Parathyroid tumors (parathyroid adenoma)
– Parathyroid cancer

Adrenal Disorders:
– Nonfunctioning adrenal tumors (eg. incidentaloma, adrenal adenoma)
– Functioning adrenal tumors (eg. hyperaldosteronism, pheochromocytoma, Cushing’s syndrome, sex hormone   secreting tumors)
– Adrenocortical cancer
– Metastases to adrenal gland
