I am a Lost and Found Specialist. I work with adults and youth from all walks of life helping them to find fulfilling, meaningful, emotionally uplifting lives.

I compassionately support individuals struggling with Loss and Grief, gently guiding them in their transformation from despair to hope.

Adoption is predicated on Loss. I am passionate about my work with all members of the adoption constellation, especially adoptees.

Caregivers and health care professionals can feel lost, and out of sync with their world when suffering from Compassion Fatigue, Vicarious Trauma, or Burnout. I have an affinity for helping caregivers and health care professionals address these issues aiding them to live fully, meaningfully, and with joy.

I work from a humanistic perspective integrating Narrative, Attachment, and Somatic Therapies with Mindfulness based strategies to assist clients in building meaningful, fulfilling lives that consider and respect their individual uniqueness, and goals.
