Abby practices primarily in the area of water law, including adjudication proceedings in the Montana Water Court and enforcement proceedings in Montana district courts.

After moving around the southeastern United States for most of her childhood, Abby earned a B.S.Ed. from Northwestern University in Evanston, Illinois. She then served in the United States Peace Corps, living and working for two years in a rural village in Malawi, East Africa. It was in Malawi that Abby developed a deep appreciation for, and interest in, the fundamental and complex relationship between water use and a community's health and food security.

When she returned from Malawi, Abby made her way to Montana where she obtained a Master’s of Arts focused on cross-cultural conflict resolution and mediation from the University of Montana in Missoula, Montana. Eventually, Abby went on to earn a J.D. with honors from the University of Montana School of Law. Prior to entering private practice, Abby clerked for the Honorable Patricia O. Cotter at the Montana Supreme Court.

In addition to her private water law and mediation practice, Abby believes strongly in giving back to the community through pro bono legal work.

Outside of her legal career, Abby, her husband Collin, and their two young sons, enjoy the great outdoor life Montana offers, especially fly-fishing, hunting, cross-country skiing, and hiking with the family dogs. Abby is also a yoga instructor at a local studio and volunteers her time teaching yoga(ish) movement and mindfulness in local preschool and elementary school programs.
