Maureen Alianza

As a follower of Jesus for many years, I am endlessly amazed at His entrance into human life and am continually dazzled by the beauty of His Kingdom as it is experienced “at hand”.  Simply breathtaking.   Such a fascination has led me into working as a nurse in the world of mental health with interest, and special training, in the area of trauma.  My current work is among those experiencing homelessness in Phoenix, Arizona.  Other leadings include co-founding a non-profit organization in 2006 that works at deepening relationships with an indigenous tribal group in the Philippines as we watch Jesus “do His thing”.   I also recently completed a Certificate in Spiritual Direction from Selah (Leadership Transformations).  And, with the belief of being “called” to a life lived in community, I have also participated and offered leadership for many years in a covenant community called Apprenticeship to Jesus (A2J) whose heart is to restore discipleship back to a way of life.

Art Guina

Spiritual Director, Retreat Leader: I completed training with the Hesychia School of Spiritual Direction in Tucson, AZ.  My academic training includes Master of Divinity and Doctor of Ministry. I’ve been on staff with Campus Crusade for Christ since 1977, having served in the Philippines and now based in Arizona. I personally prefer the term ‘spiritual companioning’ as I’m passionate about coming alongside others to, in the words of David Benner, “…help others attend to God’s presence and revelation and prepare to respond to him… thus helping people attune themselves to God.”  I’m available to meet in person or via Zoom video.
