My philosophy
My treatment philosophy is rooted in compassion, collaboration, and clinical integrity. I believe in treating the whole person—not just symptoms—by addressing biological, psychological, and social factors that influence mental health. I value transparency, cultural sensitivity, and patient autonomy, and I strive to create a safe, nonjudgmental space where individuals feel heard, respected, and empowered to take an active role in their care. I utilize evidence-based practices tailored to each patient’s unique needs, always aiming to promote long-term stability, resilience, and improved quality of life.

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.
