Who We Are
We at Keystone Streams are passionate about water quality. American water should be fishable, swimmable, and drinkable. Unfortunately, in most major waterbodies water quality does not meet these standards.
Planting Riparian Forest Buffers and upland reforestation are two of the most effective ways to improve water quality.
Our Team
Aaron McCrady
Founder and CEO
“From overturning stones in the creeks of Virginia looking for crayfish to fishing in the Chesapeake Bay with my father, I have always cherished my time spent in the outdoors. I have chosen to focus my career on protecting, conserving, and enhancing our natural places. As the grandson of a Virginia farmer, I am determined to find a way to help the farming community while improving water quality in the Bay States.”
Aaron founded Keystone Streams in 2023. Prior to Keystone Streams, Aaron originated, structured, and executed renewable energy transactions at Hannon Armstrong and SunEdison. Aaron received his Bachelor of Arts degree in Neuroscience and Philosophy and his Master of Science in Commerce from the University of Virginia.
Isabel LeBoutillier
Chief Operating Officer
“Drawn to rural outdoor pursuits from an early age, as well as the natural beauty of the Virginia countryside, I feel strongly about supporting and maintaining healthy ecologies in the mid-Atlantic. This is why Keystone's riparian forest buffers strategy is so appealing: plant trees to absorb excess nutrient runoff, stabilize soil, and improve water quality while improving land for farmers and the longevity of our natural landscapes.”
Isabel joined Keystone Streams in 2024 looking for a way to make an impact on soil health outcomes and water quality at scale. An entrepreneur, Isabel previously founded and sold a telecommunications business, after which she operated a land and estate management business in Albemarle County, VA. Isabel received a Bachelor of Arts degree in Foreign Affairs from the University of Virginia.
Kevin Tobin
Director of Operations
“My hands have been in the earth and rivers throughout my life. I am most at peace whitewater kayaking, ultra trail running, rock climbing, mountain biking, practicing primitive wilderness survival, discing cornfields on the family farm, and keeping the woods from swallowing the log home we built on family land. The strength of the connections I have with people has always been part and parcel with my connections to our natural world.”
Before joining Keystone Streams, Kevin worked as an operations manager for a modular infrastructure company. He also owned a small business and spent 24 years directing a high-adventure program based entirely in the James River Park System. During that period, he logged approximately 100 days each year on the James River, helping develop future naturalists and outdoor enthusiasts, coordinating with city and state organizations on shared priorities, and serving on the boards of Friends of James River Park and the James River Outdoor Coalition.
