Hanna grew up in a Syrian Orthodox Christian family. Even at an early age, she has already expressed her interest in the arts. Her family has been very supportive in this venture and let her train as an arts teacher.
She encountered the IMAGE magazine in the early 1980's. IMAGE magazine is the regular publication of the Asian Christian Arts Association (ACAA). It became the turning point in her journey of faith and spirituality in Christian art. Hanna became an active supporter of the ACAA and was its vice-president from 1998-2003. It was through the ACAA that she became exposed to a wider community of Asian Christian artists. She was the artist-in-residence at the Sambalikhaan in the Asian Institute for Liturgy and music (AILM) in Quezon City, Philippines in 1993, and later at the Overseas Ministries Studies Center (OMSC) in New Haven, Connecticut, USA from 2006-2007. Hanna is also a recipient of grants from the China Christian Art Association (CCAA) and the ACAA.
Hanna's works are characterized by their bright & bold colors and rhythmic lines. These are mostly the influence of her Orthodox Christian upbringing that introduced her to colorful and intricate icons; and her childhood in the tropical country of Malaysia, with its bright and lively flora and fauna, diverse culture and ethnic people and religions.
She takes great responsibility in the representation of Biblical texts. According to Hanna, "Visual images reveal more of one's mind than words. That is why art has been used in education, contemplation, meditation and veneration in Christian tradition."
