From Garrett Holg

"Blending the expressive emotionalism of the retablo painter with the grotesque visionary style of Bosch and Brueghel, her strange and disturbing works have aways suggested a dark, desperate acceptance of the inevitable." - ARTnews

From James Yood

"Woman as nature, woman as victim, woman as life-giver, woman as indefatigable source or recipient of love, sex, pain, and nurturing -- each takes a turn in her cosmology." - Art Forum International

From Ed Krantz

"The idea of transformation inherent in Symbolist art is altered in the work of Spiess-Ferris. While her figures, often women, are linked to an earthly world of roots, trees, leaves, and birds, they are also subconsciously distant. This detachment is a means for them to discover their revealed selves and to create an opening to that authentic unconscious portion that dwells unheard and unseen, covered by women's historically apportioned roles and society's masks and conventions" - Sketches, Orchards & Dark Ponds, artist's catalogue
