Committed to meeting clients at their unique life juncture, I provide a nurturing, empathetic, and non-judgmental space for the therapeutic journey. My work is grounded in the belief that the relationship between one’s inner world and outer circumstances can be both a source of struggle and a terrain for healing.

My approach is integrative, holistic, and multiculturally informed. Drawing on cognitive behavioral therapy (CBT), Eye Movement Desensitization and Reprocessing (EMDR), reality therapy, and mindfulness, I tailor each session to the individual. As an EMDRIA-approved EMDR therapist, I am trained to support clients in processing trauma at a deeper level. I also work with couples to strengthen communication, rebuild trust, and navigate relational challenges — and I serve as a clinical supervisor for emerging mental health professionals.

Holding a Master of Arts in Mental Health Counseling from New York University and an advanced certificate in LGBT Health, Education, and Social Services, my training is complemented by hands-on experience as a residential counselor in psychiatric hospitals and group homes.

I specialize in anxiety, depression, trauma, multicultural identity, relationship issues, and LGBTQ+ experiences, with a deep commitment to creating a space where every client feels seen, respected, and empowered.

I take an integrative, client-centered approach to therapy, tailoring treatment to each individual’s unique needs, experiences, and goals. My work draws from a range of evidence-based modalities, including humanistic, psychodynamic, Cognitive Behavioral Therapy (CBT), Internal Family Systems (IFS), and trauma-informed approaches.
I believe that many of the patterns, coping strategies, and protective mechanisms we develop early in life serve an important purpose, helping us navigate difficult experiences and environments. As adults, however, some of these same patterns may no longer support the life we want to live. Together, we work to understand these longstanding dynamics with curiosity and compassion, while creating space for new ways of relating to ourselves and others.

My therapeutic style is warm, collaborative, and curious. I strive to create an affirming, nonjudgmental environment where clients feel safe to explore challenges and vulnerabilities. At the same time, I believe growth often requires honest reflection and, when appropriate, gentle challenge. I also value the role of humor in the therapeutic process and find that it can be a powerful tool for building connection, fostering perspective, and supporting healing.

I work with adults, couples, and adolescents, with a particular focus on supporting members of the LGBTQ+ community. My goal is to help clients deepen self-understanding, strengthen relationships, and make meaningful, lasting changes aligned with their values.

I am a fully licensed Mental Health Counselor (LMHC) in New York State and a board-certified National Certified Counselor (NCC). I am also currently pursuing certification as a sex therapist through the American Association of Sexuality Educators, Counselors and Therapists (AASECT).

Life can be overwhelming and most of us do not have the space or the support we need to cope with life challenges. As a therapist, I provide a safe space for clients to engage in the process of self-discovery. I put a lot of emphasis on the therapeutic relationship as I believe this relationship is the catalyst for change. I like to meet clients where they are at while providing the support and structure they need. I consider myself to be emphatic, honest and non-judgmental. I strive to provide my clients with compassionate and high-quality counseling.

I have experience working with clients from different age groups and diverse ethnic background attending therapy for an array of issues such as mood disturbances, depression, anxiety disorders, substance abuse, domestic violence, trauma, stress, life transitions, and anger issues. The approach and techniques I use in therapy are based on the needs of the client. Most commonly used approaches are CBT, family systems therapy, play/art therapies, and humanistic approach. I also conduct therapy in the Spanish language for those clients in need of a bilingual therapist.

I am a licensed Mental Health Counselor. I completed my BA in Forensic Psychology and minor in human services at John Jay College. I obtained my MA in Mental Health Counseling from New York University.
