Meet Cristy

Cristy and her husband, Steven, have lived in Cairns for nearly 20 years after moving from the USA to minister in a local church. They have three teenage children who are all too quickly reaching the stage of flying the nest. She loves coffee dates with her hubby, the blues and greens of the ocean, and playing piano for church worship. She is quite sure that peanut butter and chocolate are truly a match made in heaven.

Cristy’s Counselling Approach

Cristy trusted Christ at a young age and surrendered to missions as a teenager. Her counselling approach combines deep theological understanding with clinically informed practices. She delights in helping Christians grow towards ever greater Christlikeness. Through her own life hardships and cross-cultural experience, she has become ever convinced of God’s providential goodness in her life, and desires for others to realise that same reality amid their own suffering and struggles.
