Achina Palanki Stein DO, IFMCP, DFAPA, ABIHM, FACN is an American Board Certified Psychiatrist with 25 plus years of practice experience.


She is dedicated to psychiatry and functional medicine and bridges the gap between allopathic and holistic medicine. This integrative patient-centered approach to healing offers more extensive diagnostic and treatment options needed to overcome chronic disorders.

Dr. Stein uses functional medicine to help patients find the underlying or root causes of illness and the nutritional and biochemical imbalances that may be contributing to them. Functional medicine is personalized medicine that uncovers the root cause of disease instead of focusing on the suppression of symptoms. Dr. Stein searches for underlying triggers that are contributing to your illness through cutting edge lab testing.  She will tailor the intervention to your specific needs as an individual. She may use diet, supplements, lifestyle changes or medication to treat your illness but will seek the least invasive way to help your body restore balance. She seeks to promote wellness and create hope, health and healing by partnering with you.


Dr. Stein works with patients to reverse chronic health conditions using Functional Medicine. She will analyze digestive, immune, hormonal (endocrine) and neurological body symptoms to identify the root cause of your disease or condition. Dr. Stein specializes in helping clients heal from depression, anxiety, fatigue, insomnia, cognitive dysfunction, irritable bowel syndrome, autoimmune disease, hypothyroidism, and many other disorders that Functional Medicine is best suited to treat.
