Truly accepting, non-judgmental and passionate about what I do.

I am a Double Board-Certified nurse practitioner specializing in psychiatric mental health and family health. As a dedicated psychiatric nurse practitioner, I use an integrative and holistic approach to mental health. As a family nurse practitioner, I take into consideration how physical health impacts mood and relationships. I employ evidence-based medication management. Together, we can pinpoint what's causing you stress and navigate towards a balanced state. I employ brief supportive psychotherapy in every session to help patients manage their emotions, particularly those dealing with chronic illnesses or experiencing high levels of stress. By offering empathy and validation, I aim to strengthen coping mechanisms, boost resilience, and enhance overall mental well-being.

Therapy is a collaborative process, and a strong therapeutic relationship is key to meaningful progress and lasting change. My approach is grounded in a strengths-based, client-centered perspective that supports each person’s capacity for growth and self-understanding. I strive to create a supportive, compassionate, and nonjudgmental space where you can openly explore your thoughts, emotions, and experiences at a pace that feels comfortable for you. Whether you are navigating life transitions, managing stress, or seeking greater self-awareness, therapy can provide a space for reflection, healing, and meaningful change.

I’m an experienced licensed mental health counselor and I believe that meaningful therapy starts with a genuine human connection. The relationship between client and therapist is at the heart of my work and I strive to create a space that feels warm, comfortable, and free of judgment. I bring curiosity, compassion, and humor into the room and I focus on attuning to each client’s unique needs so therapy feels personal, collaborative, and real.

While I aim to be supportive and affirming, I also believe growth often requires gentle challenge. I work to help clients notice patterns, stretch beyond what feels familiar, and engage honestly with themselves—always at a pace that feels respectful and manageable. My approach is integrative and tailored to each person or couple I work with. I’m trained in EMDR and also draw from CBT, DBT, Motivational Interviewing, and psychodynamic approaches. I enjoy working with individuals and couples, with areas of focus that include trauma, relationship concerns, anxiety, depression, substance use, self-esteem, and identity. Whether you’re looking to heal, gain insight, or make meaningful change, I’ll walk alongside you with warmth, honesty, and intention.
