As an experienced Psychiatric Nurse Practitioner based out of Long Island, NY, I offer adult patients high quality psychiatric services in the comfort of their own homes. Whether for privacy concerns, busy schedules, or difficulty getting outside, my patients are provided with a full array of psychiatry services for their mental health needs via tele-health. Conditions treated include ADHD, depression, anxiety, dementia, schizophrenia, bipolar disorder, and most other conditions as well. I offer evening and weekend appointments and work exclusively with adults 18 and over. Medicinal marijuana certifications.
As a Psychiatric Nurse Practitioner, I specialize in creating a safe and supportive environment for clients dealing with anxiety, depression, bipolar disorder, and dementia. My approach combines personalized care and evidence-based practices, including medication management, to help clients find the most effective strategies for their unique needs.
I know how difficult it can be to reach out for help, but I want you to know that you don’t have to face these challenges alone. Together, we’ll explore what’s happening in your life, uncover your strengths, and create a plan that feels right for you. Let’s take the first step toward building the life you deserve.
