Blackstone NP In Psychiatry PLLC
Psychiatric Mental Health Nurse Practitioner - Full-time
Jul 2018 - Present
In my role as a Board-Certified Psychiatric Mental Health Nurse Practitioner, I have independently managed a diverse caseload of psychiatric patients across the lifespan in a telehealth private practice setting. I conduct comprehensive psychiatric evaluations, develop and implement individualized treatment plans, and provide evidence-based pharmacologic and psychotherapeutic interventions. I ensure compliance with current clinical guidelines, prioritize risk management, and maintain thorough documentation to support clinical decisions and mitigate liability. I have demonstrated strong clinical judgment, reduced symptom burden in high-risk populations, and maintained continuity of care while navigating complex comorbidities and social determinants of health.
