As a physician, my passion is to educate and empower my patients with truth and inspiration. To me, wellness is not the absence of disease, but rather a life of happiness, health and vitality. My medical wisdom is rooted in integrative treatments and a command of Western and Eastern medicines. My interdisciplinary background provides a variety of tools that help patients achieve success. Rather than focusing on symptoms, I address the whole person using a multi-faceted lens and treat them through orchestrating bio-identical hormones, IV nutrition therapy, heavy metal detoxification, and vitamin shots. I welcome the challenge of complex medical issues spanning from low energy, poor sleep, brain fog, weight issues, and hormonal and immunological imbalances.
