Nicole Vaughn, PMHNP-BC

NOT ACCEPTING NEW PATIENTS
Practicing at Changing Minds Psychiatry, Mrs. Nicole Vaughn serves the community of Las Vegas, NV. Mrs. Vaughn is a concerned psychiatric and mental health nurse practitioner, board certified, who attended Eastern Kentucky University, where she received her masters degree in psychiatric and mental health nursing.
Every day is a new opportunity to change the world. I live my life with that thought every day. ‘Life is too short to be unhappy’ my patients often hear me saying. Some people just need hope. When I can’t give a cure or an antidote, I try to instill hope. That’s what I can give. My passion to help people help themselves started before I could even spell the word Psychiatry. I was a young girl encouraging others to always do their best and hoping with them for better tomorrows. I never dreamed I would be in the position I am today. I wake up everyday with a new mission…. To help others believe in themselves and happiness again.”.
She feels that the practice of psychiatry is both her “passion and her purpose.”

She understands that each person’s story is unique in the causes leading up to mental disorder, and knows it is important to understand the underlying reasons as well as the current symptoms.
