Dr. Dinh is passionate about doing what she does because “We, as humans, all have emotions. Even the strongest can break at times. Mental illness does not discriminate and can happen to anyone in their lifetime. We need to de-stigmatize mental illness and normalize mental health treatment as a priority. My hope is to be able to provide my patients with the tools they need in order to be successful in whatever challenges they may be facing”.
