I'm Martha, a Psychiatric and Mental Health Nurse Practitioner and the owner of Mosaic Psychiatry & Psychotherapy. I offer virtual mental health medication management and psychotherapy services based out of Brooklyn, NY.
I bring 16 years of nursing experience to my practice, and am dedicated to providing holistic, person-centered care across a wide variety of mental health challenges. My approach is rooted in looking at the whole picture of who you are and what your goals are for yourself.
My expertise lies in treating individuals navigating depression, anxiety, mood disorders, trauma, and the mental health aspects of chronic disease. Beyond diagnosis, I focus on foundational elements of wellness, including:
I offer targeted therapies and medications individualized for each person. My desire is to bring care that is authentic and aligns with each patients goals and values. Care designed to feel human.
I believe we all need to be heard and treated with respect and dignity. Treatment involves us working together to get the best results.
