Prior to joining Kirkland, Sarah was a core member of the team that obtained a landmark decision invalidating California’s Proposition 8 on the grounds that it violates the United States Constitution. Sarah’s work on this case has been profiled and mentioned in corresponding media coverage, as well as in the documentary and book that trace the litigation. Today, Sarah maintains an active pro bono practice that focuses primarily on civil rights litigation. Prior to law school, Sarah spent several years as a complex database designer.
