About The Provider

Welcome!

       I'm Marsha Desrosiers, a dedicated board-certified psychiatric nurse practitioner (PMHNP-BC) with over 15 years of experience providing compassionate mental health care. As a New Yorker, I've had the privilege of working with a diverse population, fostering a deep understanding of the unique challenges faced by individuals from all walks of life.

       After graduating from high school, I attended St. Joseph's College in Brooklyn, where I earned a Bachelor of Arts in Psychology. I completed a Bachelor of Science in Nursing at Adelphi University and later obtained a Master of Science in Nursing with a specialization in psychiatric mental health from Molloy University.

       As a PMHNP-BC, I specialize in providing comprehensive mental health care to patients across the lifespan. My expertise lies in developing personalized treatment plans that address a wide range of mental health conditions, including anxiety, depression, ADHD, personality disorders, mood disorders, bipolar disorder, schizophrenia, and more. I utilize evidence-based therapeutic approaches such as Cognitive Behavioral Therapy (CBT) and Solution-Focused Therapy (SFT) to empower individuals to overcome challenges and achieve lasting mental health.

       From my early days as a secretary in psychiatry to becoming a nurse practitioner, I've gained invaluable insights into the complexities of mental health. The COVID-19 pandemic underscored the urgent need for accessible mental healthcare, and fueled by my passion for helping individuals reach their full potential, I founded Blackstone Psychiatry.

       By choosing Blackstone Psychiatry, you're choosing a partner committed to your mental health journey. We're here to support you every step of the way, helping you discover your inner strength and resilience, like a precious gem unearthed.
