Welcome to ROC Psychiatry, I am so glad that you found us. I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP) in the state of New York with over a decade of experience in the field of psychiatry. My career began as a registered nurse working in inpatient, emergency psychiatric, and outpatient settings, and since obtaining my license as a PMHNP, I have been dedicated to providing compassionate, personalized care as a PMHNP. I specialize in psychiatric evaluations, diagnosis, and medication management for a wide range of mental health conditions.

I believe that the best outcomes come from a collaborative, individualized approach to treatment. I value open, honest communication and work closely with each patient to create a treatment plan that reflects their unique needs, values, and goals. My philosophy centers on using the fewest medications at the lowest effective doses, with shared decision-making as a cornerstone of care.

Outside of work, I enjoy spending time with my family, playing golf, and retreating to the mountains. To me, my patients are more than just a number—life doesn't stop when we face challenges, but together, we can work through them and get you back to a place of balance, function, and fulfillment.

Hello and Welcome!!  I am so happy you  have decided to work toward improving  your mental wellbeing. You deserve it!!  I am a Board- Certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with 25 years experience practicing  as a healthcare provider. I have dedicated my career to providing compassionate mental health care to adults with various needs  across different settings including outpatient clinics, inpatient units, emergency services (CPEP), the Deaf Wellness Clinic, Personalized Recovery Program (PROS), long term care, group homes, and private practice. The ability to draw on my vast clinical experience and knowledge leaves me well equipped to provide you with excellent, evidence- based care. 


I understand all too well how difficult life can feel when struggling with your mental health.  It  makes  a world of difference to  have a  provider who takes the time to listen and who is  invested in helping you find symptom relief and improved quality of life. My philosophy is one that values collaboration and shared decision making, where we work together to best understand your  unique clinical picture and  decide on a plan that  reflects your individual values and treatment priorities.  I take a  comprehensive and holistic approach with consideration  to  the biological, psychological, and social factors known to affect  mental well being.  I primarily offer  psychiatric evaluations,  psychotropic medication management, treatment recommendations/ referrals and am happy to collaborate with other providers involved in your care.  


I am so glad that you are taking steps toward emotional wellness and  it  would truly be an honor to  partner with you on your journey.
