Our Founder

Robert Wiltshire

Robert Wiltshire founded the Invasive Species Action Network in 2008 realizing that the current efforts to address the aquatic invasive species problem fell short. With a well-rounded career conducting wild trout studies for the state of Montana for over 15 years, small-business entrepreneur in recreation and hobbies, and conservation non-profit manager for more than a decade, Bob navigated his role as executive director with ease. He played key roles in the management of invasive species over the years including serving on the Montana’s Whirling Disease Task Force, co-authoring the Western States New Zealand Mud Snail Management plan and serving on the National Invasive Species Advisory Committee to the White House. In 2019, Bob retired from ISAN to pursue his personal goals and hobbies.

Our Staff

Leah Elwell

Prior to taking the helm at ISAN, Leah led our programs for almost a decade. She often cannot believe that she has spent the majority of her life working on invasive species issues.  Now more than ever, Leah remains focused on bring partners together to tackle the complexities of invasive species. When not dreaming up new ways to change the world for good, Leah is digging in the dirt, hiking the hills and having fun with her family.  

Marya Spoja

Marya brings with her a decade of experience in the fishing industry. By spending her summers as a fishing guide and in fishing retail, and her winters as a dogsledding guide, her career has long revolved around water in its various forms. Through these experiences Marya has seen first-hand the relationship between water and her local economy, a complex relationship that over time fostered in her a desire to do more for those who enjoy spending time on the water. When she isn’t guiding or working on our various outreach programs, Marya beats the door down to spend some more time outside.

Mason Parker

Mason Parker is the newest addition to the ISAN team. He received is MS from the University of Montana in 2019. As a graduate student, he conducted field research with a focus on invasive species. His primary interest was the flowering rush, an aquatic invasive plant quickly spreading through the waters of the western US. Mason brings years of experience in project management to the job, as well as a passion for reducing the spread of invasive species. He spends his free time in a kayak or hiking long trails into the Montana backcountry.
