Guided fishing trips with Chris Doeberl

Chris Doeberl (office manager and guide)

Fairfield, CT

Specialty: Easy to get along with and passionate about the rivers.

I was born in Connecticut on Long Island sound. I spent my teen years growing up in Vermont where my love for fly fishing began to grow. After working as a psychiatric counselor for 5 years I decided to move to the Jackson Hole area and pursue a guide carrier. I have been guiding the rivers and lakes surrounding the valley for 9 years. In my off season I work as an AASI certified snowboard instructor at the Jackson Hole Mountain resort. When im not fishing or snowboarding I enjoy backpacking, biking, whitewater, and music. I feel blessed to call Jackson my home and even more blessed to guide the surrounding waters. There is no feeling like floating beneath the Grand Tetons fishing for native cutthroat trout with dry flies.

Guided fishing trips with Tom Montgomery

Tom Montgomery- Seasonal

Jackson Hole, Wyoming

I started fly fishing as a schoolboy in England back in the mid to late 1960s – and it changed my life!  Later, I went to Middlebury College in Vermont where I received a degree in English literature before finally launching my career as a guide.  I’ve worked in Alaska, throughout the state of Montana, on the South Fork of the Snake in Idaho, on Little Cayman in the British West Indies and here in Wyoming on our fabulous Snake River.  In the off-season I organize and lead trout trips to New Zealand, Argentine Patagonia and the historic chalk streams of England’s southern counties.  In addition, I’ve had a parallel career as an editorial and commercial photographer with an emphasis on travel and fly fishing.  I’m thankful every day for this half-century love affair with a fly rod and a set of oars…and so far there’s no end in sight!
