Kind Words

  • Before hiring Sara, we knew we wanted to remodel our home and backyard to be more functional. We have four children and love to host indoor/outdoor events. Sara helped us design the entire space, from initial layout to the materials and furniture. We had various priorities, and she was able to meet everything we hoped for, all within our desired budget.

    — Connor & Kristy, San Francisco

  • I found Sara totally professional as well a pleasure to work with. She listened well, was responsive and consistently worked hard and efficiently to match what I had in mind for my space.
