Current Board of Directors


Logan Krieger - President

Raised in the Traverse City area from a young age, Logan was lucky enough to have an amazing grandfather that shared his passion for fly fishing with him at the age of 10. While in college he worked on road stream crossing projects, electro fishing studies, and parkland efforts. After receiving a BA in biology/ ecology, he spent 2 years guiding on the Aniak River in Alaska and the Rio Cisnes in the southern part of Chile. He has a true passion for our resources and is honored to serve to protect our cold-water streams.


Liz A. Petrella - Vice President/Immediate Past President

Liz is committed to helping ACTU grow their outreach, educational, and conservation opportunities. This includes her four grandchildren whom she hopes will have the opportunity to experience all that the rivers have to offer.  Being elected a second term for this chapter is a privilege and she appreciates the opportunity to serve. Liz grew up spin casting and ice fishing. However, once she learned to fly fish, she became hooked on the local trout in the streams and rivers of Northern Michigan, she has a special spot in heart for the Boardman River. Since becoming a member of ACTU, Liz has tried to expose as many as she can to cold-water conservation which is at the core of our mission.


Keith Koonmen - Treasurer

Keith relocated to Traverse City from Grand Rapids in October of 2019. He was introduced to fly fishing at a young age by his dad. His love of fly fishing has naturally grown into a passion for protecting the cold-water fisheries and environment where trout live.
