Hi, I’m Kaliym Howell, PMHNP. I’m a board-certified psychiatric nurse practitioner with experience in inpatient psychiatry and outpatient medication management. I specialize in treating anxiety, ADHD, depression, trauma-related conditions, and life transitions using a calm, collaborative, and evidence-based approach. My goal is to provide thoughtful, personalized care that helps you gain clarity, stability, and long-term wellness.
I am a board-certified psychiatrist and psychotherapist with expertise in medication management, psychoanalysis, CBT and mindfulness-based therapy. I also have expertise in interventional treatments (ECT, TMS, Ketamine & Psychedelic therapy) and work as a clinical professor at Northwell Zucker Hillside Hospital. I work with adults (ages 18 to 65) and have openings in the evening for busy working professionals. I specialize in treating a wide array of conditions: Depression, Anxiety, OCD, Social Anxiety, and Insomnia. At this time, I am only taking patients who are interested in medication management not individual therapy.
Dr. Yina Cruz-Harris specializes in "Medication Management Evaluations" and treats array of psychiatric diagnoses across the lifespan, ranging from ADHD, depression, GAD, and ODD to aggression, insomnia, and mood disorders.

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’m a psychiatric nurse practitioner specializing in care for women, children, and adolescents, with a strong focus on ADHD, anxiety, and mood concerns. Many women seek care during periods of burnout, emotional overload, or major life transitions, and I provide calm, supportive, and collaborative care during these difficult moments. I also work closely with parents, helping children and teens feel safe and understood while supporting families with clear guidance and thoughtful treatment planning.
I’m a psychiatric nurse practitioner providing telehealth medication management for adults across New York. I specialize in treating ADHD, anxiety, depression, mood disorders, and stress-related concerns.
My approach is structured, evidence-based, and focused on measurable improvement. We work together to clarify what’s driving your symptoms and create a clear, practical treatment plan. When medication is appropriate, I aim for options that are effective, well-tolerated, and sustainable long-term.
I primarily work with adults seeking focused, collaborative psychiatric care via telehealth.
What I Treat Most Often
I provide comprehensive psychiatric evaluations and ongoing medication management through secure telehealth appointments for adults in New York.
As your mental health provider here's what I want you to know about me:
I have the most experience working with the adult population. My ideal client is not someone with a specific diagnosis or past experience. It is someone who is battling something within them and is seeking a helping hand to hold on. Treatment with the most appropriate medication can help a person overcome and persevere. I hope to work with patients who really want to make a change in their lives. I like to treat my patients holistically with medications that safely help them. I hope that my patients seek my guidance because they want to challenge themselves. Together, we can make tomorrow a better day.
