We are a general endocrinology clinic and have been serving the Tallahassee, Florida area for more than 20 years. Each of our three providers has more than 20 years of experience in treating endocrine disorders. We pride ourselves on providing quality, comprehensive care. 

We treat patients with the entire spectrum of endocrine disorders - diabetes mellitus, hypertension, lipid disorders, obesity, disorders of the thyroid function, thyroid nodules and thyroid cancer, metabollic bone disease, reproductive disorders, parathyroid disease and other disorders of calcium metabolism, and pituitary disorders. Many of our patients have complex combinations of these and we manage each. We believe that this holistic approach yields the best clinical outcome.

Mission Statement

Our mission is to better the health of our community by providing superior medical care with a focus in endocrinology.  We will care for our patients in a respectful manner and with the recognition that health is not merely the absence of disease but encompasses the full physical, mental and spiritual well being of the individual.
