Dr. Teresita Barrantes, NMD
Women’s health specialist
Hormone specialist
Naturopathic physician
I’m Dr. Teresita Barrantes, a naturopathic physician practicing in the vibrant state of Arizona, and the co-owner and co-founder of TECM Health. My areas of expertise encompass women’s health, digestive and hormone imbalances, weight loss, and chronic pain. I’m proud to say that I’m fluent in both Spanish and English, enabling me to connect with a diverse range of patients. I find great joy in serving the Hispanic community through my practice at TECM Health in Mesa, Arizona.
My educational journey began at the University of Costa Rica in San Jose, Costa Rica, where I pursued and completed a bachelor’s degree in Chemical Engineering. However, my true calling led me to the field of naturopathic medicine. I achieved my Doctor of Naturopathic Medicine from the Southwest College of Naturopathic Medicine in Tempe, Arizona.
I truly believe that embracing a holistic approach to care — treating the entire individual and the underlying causes of their ailments, rather than merely alleviating symptoms — is the best way for patients to get results and finally feel better. This approach is particularly effective in my work with women’s health, where I specialize in conditions like premenstrual syndrome (PMS), menopause symptoms, anxiety, and polycystic ovarian syndrome (PCOS), among others. I’m also proud to hold certification as a BioTE® provider, equipping me with the expertise to evaluate and treat hormone imbalances in men and women.
My mission is to empower you to achieve optimal health, addressing not only the symptoms but the root causes of your health concerns. From nutritional counseling and acupuncture to IV therapy, Bioidentical hormone therapy (BHT), herbal medicine, nutritional supplementation, and prescription management, I offer a comprehensive array of options to foster healing and wellness.
My husband, Dr. Corey, and I founded TECM Health, to help patients achieve their best health and provide them with a better, comprehensive healthcare experience than what the conventional model offers. With our extensive training, unwavering dedication, and genuine care, we’re here to guide you towards a balanced, healthy, and fulfilling life.
