I'm a licensed clinical social worker dedicated to creating a nurturing space where my clients feel space to explore their thoughts, emotions, and experiences. I strive for therapy to feel collaborative and authentic. I meet clients where they are and tailor my approach accordingly.

In my time working with patients, I have noticed two common denominators. Suffering and change. We all suffer in our own way. Wants we cannot have. Love that is unreciprocated. Thoughts that won’t leave us alone. These things are the inherent challenges of life. The magnitude of our suffering is matched only by the capacity we have for change. To change our mood. To change our way of thinking. To change the way we interact with others. To change the way we interact with ourselves. No matter the change, it starts with knowing it is possible and identifying the first step needed. Reach out today and we will take that first step.

I have experience working with individuals with anxiety, depression, trauma, personality disorders, relationship issues, and many other concerns. Using an eclectic style of therapy, I pull from different approaches to meet the needs and goals of each person. Underlying any approach is a culturally competent foundation of empathetic support.

In session, you will have a safe place to process and learn how to cope with what is happening outside of session. You will be supported unconditionally. Together, we will work to better understand the changes that are needed to be the best version of yourself.

In my practice, I work with individuals navigating depression, anxiety, insomnia, ADHD, or dementia who are ready for change but may feel uncertain about where to start. Together, we will identify your unique needs, set meaningful goals, and create a personalized plan that supports healing, growth, and long-term well-being. My goal is to help you not just manage symptoms but rediscover balance, resilience, and hope.

I work with children, parents, and couples, helping families navigate life's challenges, strengthen relationships, and develop healthier patterns of communication and connection. Whether your child is experiencing emotional or behavioral difficulties, you're facing parenting challenges, or you're seeking to improve your relationship with your partner, I approach therapy with compassion, curiosity, and respect for your unique experiences

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’m glad you’re here. I’m a warm, down-to-earth, and non-judgmental therapist who truly wants to know you—not just what’s going wrong, but who you are as a whole person. I work with people navigating anxiety, depression, relationship issues, trauma, grief, and LGBTQIA+ concerns. Clients often tell me I’m easy to talk to, compassionate, and genuinely invested in their growth. If you’ve been looking for a space where you can feel understood and supported, you’re in the right place.

I believe that one of the bravest and most meaningful steps a person can take is beginning to understand their own story. My approach to therapy is holistic, recognizing the interconnected nature of emotional, mental, and personal well-being.

I am committed to meeting you where you are, working collaboratively at a pace that feels comfortable and appropriate for you. Together, we can explore and address the challenges that may be impacting your growth and well-being.

I look forward to partnering with you to gain deeper insight, foster meaningful change, and help shape the future you envision for yourself.

I’m a bilingual (English/Spanish) Licensed Clinical Social Worker who believes that therapy works best when it feels like a partnership—not a one-sided process. I approach each session as a space where we work together to better understand your experiences, patterns, and goals.

As a Licensed Clinical Social Worker in the states of New York, Colorado, and New Jersey, I've had the opportunity to work with children, teens, adults, couples, and families in various settings. While providing behavioral health supports, I've had the ability to partner through the process of healing wounds that serve as an impediment to wellness.

​

Within my practice, I utilize Brainspotting, mindfulness, cognitive behavioral therapy, motivational interviewing, trauma focused, play therapy, and solution focused therapy to aid in reaching a state of homeostasis.

I believe in empowering my clients by fostering self-compassion and reclaiming personal agency. If you are looking for a tailored approach that respects your story, I invite you to reach out for a consultation.
