To reduce the human-caused spread of invasive species by promoting behavior change.
Leah ElwellPrior 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.
Matt WilhelmMatt Wilhelm joined ISAN in 2009 with over 12 years of experience reaching out to youth on aquatic education. Matt specializes in teaching concepts about river ecology, aquatic invertebrates, native fish species, aquatic and weed invaders, and fly angling education. Wilhelm has been a contract provider of aquatic education needs in schools across Montana for the last 20 years and has worked with nearly 100,000 people over the years. He is a nationally recognized instructor who has been teaching teachers about fly fishing and in 2004 he was honored with the Montana American Fisheries Society Aquatic Educator of the Year Award. In 2018, Matt was recognized by the Montana Environmental Education Association with the Sense of Wonder Recognition Award.

Marya SpojaMarya 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 ParkerMason 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.
Robert WiltshireRobert 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.
We consider ourselves lucky to have board members who active in our local community and interested in helping us to get the word out about preventing the spread of invasive species.

Are you interested in helping us to reduce the human-caused spread of aquatic invasive species? The Invasive Species Action Network is seeking to make an impact in areas of business and conservation to show that every small positive behavior change is a victory in the fight against invasive species introduction and spread.
Interested in getting involved? Volunteer opportunities change depending on the location and time of year, but fall into several categories: classroom-related and event-related.
Classroom volunteers are subject to host-school policies, including background checks. Once the school has approved you, you can help Matt teach kids to tie flies, teach aquatic education, assist with (or teach, if that’s your thing!) field trip presentations, and generally help keep any student chaos to a minimum.
Event volunteers must be interested in helping to spread the Clean, Drain, Dry message to anglers, paddlers of all stripes, and people of all ages. ISAN attends a variety of events, depending on the time of year. No specific skills are required, but an interest in the subject of the event you attend is helpful.
