I am a registered clinical psychologist. My training qualifies me to work with adults seeking a variety of mental health services including mood, anxiety and trauma. In addition, I have research and clinical experiences directly related to the field of Oncology and as a result have a strong interest in working with individuals who require psychological support following a cancer diagnosis.
