Bruce Morrison

Bruce A. Morrison, JD
President and Attorney
Email Bruce

Bruce has served at Great Rivers since its founding: as General Counsel for many years and as President today. Cases in Bruce’s docket have included protecting parks and wilderness areas, improving air quality and public health, and protecting and preserving our Region’s rivers, wetlands and floodplains. Bruce graduated from Purdue University in 1981 and Washington University School of Law in 1988. He enjoys the outside and commutes to the office on his mountain bike throughout the year (as long as the temperature is no colder than 10 degrees). In the summer, you will find him swimming laps in the local municipal pool. He still occasionally camps and kayaks, although his body now protests more than it used to.

Sarah Rubenstein, JD
Staff Attorney
Email Sarah

Sarah joined Great Rivers after gathering more than 20 years of successful litigation practice both in private practice and as a staff attorney for the Interdisciplinary Environmental Clinic at Washington University School of Law. Sarah pursued her law degree out of her concern for and interest in protecting the environment, and is excited to be able to return to her original mission. Sarah graduated magna cum laude from Amherst College in 1992 and the University of Chicago Law School in 1997. When she is not fighting to preserve our natural world, Sarah can be found playing with her dogs, riding horses, tending her vegetable garden, or traveling the globe.
