I am a Licensed Clinical Social Worker with a strong background in trauma-informed care, anxiety treatment, and grief work. I believe therapy should feel safe, collaborative, and respectful of your lived experience. I understand how past trauma, chronic stress, and life transitions can shape the nervous system and impact daily functioning, even when life looks “okay” on the outside. My role is to meet you where you are, without judgment, and help you make sense of your experiences while building practical tools for healing. I value authenticity, emotional safety, and meaningful connection in the therapeutic relationship.

Humans heal through relationships. Our wounds form in connection, and it's in connection that they're repaired. This is especially true for couples: the patterns that cause pain are often the same patterns that, with the right support, can become a source of deep healing and renewed closeness. Working together means creating a safe space to slow down, understand each other's underlying needs, feeling and sensitivities, and rebuild trust and connection from the ground up.

This process can be challenging and may surprise you, but it often leads to real growth, deeper intimacy, and lasting change that is ultimately liberating.
