Welcome To Princeton Integral Endocrinology

Office is currently closed to new patients. Please, check again after January 1, 2019

Our vision is to provide gentle, compassionate care to those affected with endocrine disorders.

Our mission is to deliver integrative endocrine care to those affected with endocrine conditions.

Princeton Integral Endocrinology LLC is strongly based on Western, academic endocrinology and recommends allopathic treatments as well as nutrition, mind-body medicine, herbal remedies, supplements, and exercise when appropriate.

What you can expect. During your visit, Dr. Benito will take a detailed history and perform a medical examination. She will review any pertinent medical records that you bring with you. With all that information, she will first develop a plan for the evaluation of your condition and later, usually during a second visit, an integrative treatment plan tailored to your particular situation. During this process, she works alongside with you in evaluating the cause of your symptoms and discusses the possible treatment options. You are a necessary partner in this process.

Maria (Adi) Benito-Herrero, M.D. is board-certified in Endocrinology, Diabetes, and Metabolism. She attended medical school in Spain and completed a residency in Internal Medicine at Pennsylvania Hospital (University of Pennsylvania Health System) and a fellowship in Endocrinology, Diabetes, and Metabolism at the University of Pennsylvania. She has also completed a two-year fellowship in Integrative Medicine at the University of Arizona Center of Excellence in Integrative Medicine, where she is guest faculty. She has developed the curriculum for an integrative endocrinology module which has been incorporated to the fellowship. She is a certified meditation teacher (Khalsa Healing Arts and Yoga Center) under the mentorship of Mahan Rishi Singh and Nirbhe Kaur Khalsa and she is currently studying herbal medicine at the David Winston's Center for Herbal Studies.

In her clinical practice, Dr. Benito applies the knowledge obtained through rigorous academic research and clinical training in endocrinology and distills it through the wisdom of integrative medicine. Dr. Benito's main interest is in the prevention of endocrine disorders and sees patients with Hashimoto's thyroiditis, hypothyroidism, hyperthyroidism, osteopenia (or low bone mass) and osteoporosis, metabolic syndrome, PCOS (polycystic ovarian syndrome), pre-diabetes, menopausal symptoms (including those patients with breast cancer), and patients with diabetes for an integrative treatment plan. Dr. Benito does not practice functional medicine, but an integrative approach to conventional endocrine disorders.
