Jon Warren

I moved to Oregon from Los Angeles in the early 70s at the age of 22.  I went to work in the hi tech industry that was in its beginnings here in Oregon.  I worked nights to complete a degree in manufacturing technology at PCC.  Over the next 35 years I worked in many fields of hi tech manufacturing, from system design , manufacturing engineering and Project management. I have had the good fortune to travel many parts of the earth and there is no place like what we have here in South County. Four years ago my wife and I retried to our home overlooking the Nestucca river and our beautiful valley. It is an enchanting view.

I have fished the waters of Tillamook County for the past 40 years. I have seen many changes to our watersheds some good, some bad. My goal is to be part of the good and help in restoring our stream habitats in the waters I fish. I am a strong advocate for healthy watersheds and rivers on the North coast. “Healthy rivers are a source of life”
