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:
Each client is an individual which requires not a one size fits all treatment approach. I have over 10 years of prescribing experience in inpatient and outpatient settings and unde4rstand that not every person requires the same treatment plan. I also provide MAT, ie, suboxone, vivitrol, naltrexone for Opioid Use Disorder and Alcohol Use Disorder in a non judgmental private setting.
I am a warm, open-minded, and compassionate clinician who values collaboration and respect in every session. I provide both talk therapy and medication management, tailoring care to each person’s unique needs and goals. My approach combines evidence-based techniques with a supportive, client-centered style, helping you navigate challenges while building resilience, personal strengths, and a sense of meaning in your life.
I strive to create a safe, non-judgmental space where you can explore your thoughts and feelings openly, ask questions about treatment, and feel empowered to make choices that support your mental health. Whether you’re seeking therapy, medication support, or both, I partner with you to develop a plan that works for your life, pace, and values.
