She brings to GWWO her passion for the design of innovative spaces, forms and environments which sensitively respond to the specific constraints and opportunities of each project. Recently, she has focused primarily on educational projects at the primary, secondary and collegiate levels, including work on the new Frederick High School, the new Maryland Institute College of Art Dolphin Building and campus-wide renovations and additions for Greenspring Montessori School.
