“Lest this all sound banal and humdrum, what gives Callaghan’s paintings their primary appeal is a brush technique in which every low-velocity stroke is separate and distinct, almost as if they were cut from colored paper. He treats selected forms and textures with a single, descriptive stroke that stands out against flat, uninflected areas of color or bare canvas...”

 “…The effect is highly graphic, as if painting were a form of drawing for Callaghan. It also communicates a high sense of alertness, as if the artist treasures being completely awake and mindful in the quiet moments he records.”
