I am a Psychiatric-Mental Health Nurse Practitioner with over 20 years of nursing experience, including emergency care. I am passionate about mental health and providing holistic, patient-centered treatment through a combination of medication management and therapeutic support. My goal is to help patients feel heard, stabilized, and empowered in their care.

My name is Gillian Foster and I am a board-certified Nurse Practitioner with dual certification as a Family Nurse Practitioner and Psychiatric Mental Health Nurse Practitioner (DNP, FNP-BC, PMHNP-BC). I take a holistic approach to care, addressing both mental and physical health needs. I specialize in treating anxiety, depression, mood disorders, and stress-related concerns using evidence-based, individualized treatment plans. My approach is collaborative, supportive, and nonjudgmental, with a focus on helping clients feel heard, balanced, and in control of their well-being.

I am a Licensed Clinical Social Worker (LCSW) with a Doctor of Social Work (DSW) degree specializing in trauma-informed care and holistic emotional wellness. With over fifteen years of experience in medical and mental health settings, I have worked with individuals facing anxiety, depression, trauma, grief, life transitions, and relationship challenges. My counseling approach integrates evidence-based therapeutic practices with Christian principles to support healing of the mind, body, and spirit. I am passionate about creating a compassionate, nonjudgmental environment where clients feel safe, supported, and empowered to grow in both emotional wellness and spiritual strength. My goal is to help clients develop practical coping strategies, deepen their faith, and move toward lasting healing, purpose, and restoration.

I am a board certified psychiatric nurse practitioner and I offer psychiatric services through Telehealth, allowing clients to attend appointments from the comfort and privacy of their own space.

Starting mental health care can feel overwhelming, and many people seek support when they feel stressed, stuck, or unsure how to cope. I provide a compassionate, nonjudgmental space where you can speak openly. Together, we’ll work to understand your challenges and develop strategies that support healing, resilience, and lasting emotional well-being.

I received my B.A. in Psychology at Macaulay Honors College, CUNY, and my M.Ed. and M.A. in Mental Health Counseling at Teachers College, Columbia University.

After graduating, I have been working as a therapist since 2021 with a specialty in the LGBTQ+ community. I have worked with depressive, anxiety (generalized, OCD), ADHD, mood, personality disorders and disordered eating. Experience includes working with issues of self esteem, stress, relationships, parenting, gender, identity, race/ethnicity, immigration, grief, trauma, substances, habits, motivation, focus and attention.

My interests and clinical focuses include self-care, minority body image, Latinx mental health, psychosis in youth, and am passionate about self-acceptance/love. I created and use the motto "Write your own narrative" in my annual bootcamp as a reminder that we each have our own story and control over it.

I'm a licensed mental health counselor with formal training in Dialectical Behavior Therapy (DBT) and a background in crisis stabilization — which means I've worked with adults navigating some of the most intense emotional experiences imaginable, and I know that the hardest moments don't define where someone ends up. My style is direct and warm. I'm not the kind of therapist who nods a lot and says "how does that make you feel?" — I'll actually teach you skills, explain what's happening in your brain and body,

and work with you to figure out what gets in the way of the life you want. I also happen to believe that therapy doesn't have to be heavy all the time. Humor and humanity belong in the room too. I work with adults across New York via telehealth, and I accept Aetna, Cigna, Carelon, and Highmark plans.

Welcome! I have been in the social work field for over six years. I have had a wide variety of experiences which have deepened my understanding of mental health as well as the external factors that affect our daily lives. I specialize in working with adults with depression, anxiety, and ADHD.
