Hi! I'm an experienced and compassionate PMHNP-BC and dedicated to providing exceptional mental health care. I received a Doctorate in Nursing Practice from the university of Tennessee Health Science Center. Also certified in Family Practice, Adult Gerontology, Acute Care. With over 10 years of experience in the nursing field, I specialize in diagnosing and treating a wide range of psychiatric disorders, including anxiety, depression, bipolar disorder, ADHD (I DO NOT prescribe stimulant medication, such as Adderall, Ritalin, Vyvanse or Folacin), etc.
I provide holistic, compassionate, and spiritual support to individuals facing end of life and the support of their loved ones.
