Meet Our Guides

Scott Nichols

My grandmother taught me to fly fish in the Black Hills of South Dakota on my summer vacations. My father taught me the love of the outdoors fishing in northern Minnesota in my childhood. My highlight is to watch a person pick out a fly, tie it on and present it in a manner that the fish will rise to it. Through fly fishing I’ve had the pleasure to meet some truly amazing people in some incredible places.

Nicky Mill 

I’ve been a fly fishing guide in the Roaring Fork Valley since 2015. My father, Andy, moved to Aspen in 1960 and at a young age began fishing the Frying Pan and the Roaring Fork River, which is where I now guide. Growing up in South Florida, fishing has been in my DNA from day one. My father would take me bass fishing in the local golf course ponds after school almost everyday. On the weekends, we would take our skiff out and head down to Miami or the Keys to chase tarpon, permit, sharks, & barracuda on the flats.

Upon graduating from Lynn University with a business degree in 2016, I soon moved to NYC to work at a creative agency. A year later, I realized big, noisy cities were not for me and I needed to get back to the mountains where I now call home. In 2020, my father and I started a fishing/hunting podcast called “Mill House Podcast” that has gained a lot of traction in the past year. Throughout the years, I have fished in Alaska, Venezuela, Costa Rica, Panama, Cuba, Belize, Bahamas, Australia, & New Zealand.

Cam Martineau

Originally from the seacoast area of New Hampshire, I moved to the Roaring Fork Valley in 2018.  I am an avid outdoorsman — former rock climbing and mountaineering guide turned fisherman.  While I enjoy all types of fishing, I take special interest in Euro nymphing and hiking out to alpine lakes to fish.  When I’m not casting a rod, I’m out skiing or camping in the desert.

Riley Arendt

I’m originally from Whitefish, Montana, where I developed a deep love for the outdoors and spending time on the water with a fly rod in hand. I’ve been fortunate to explore many of the waters around Aspen and have truly enjoyed getting to know the rivers and streams in this area. One of the things I enjoy most is sharing what I’ve learned with others, especially introducing kids and beginners to fly fishing. There’s nothing quite like seeing the excitement on someone’s face when they hook into their first beautiful fish. Helping people experience that moment and appreciate the outdoors is incredibly rewarding.

John Dietsch

I’ve been fly fishing in the valley since 1984. I have gained a reputation in the fly fishing industry as an award winning fly fishing author, TV producer/host, guide and film consultant for projects like A River Runs Through It and Netflix’s OZARK.  I love getting all levels of fly fishers on the water to learn more about the river and the sport as well as where and how to catch the big one!

Chase Kelly

My name is Chase Kelly, and I was born and raised in Aspen, Colorado. I’ve spent my life exploring the incredible local waters that surround this area. I have a particular passion for sight fishing for large cutthroat trout in high alpine lakes, as well as float fishing along the lower Roaring Fork and Colorado Rivers. When I am not on the river I will most likely be exploring the mountains on skis.

Cameron Carlson

Born in Vail and grew up in Frisco, Colorado, safe to say the mountains have always been my home. Fishing has been part of my life since I was a little kid in Summit County, taking the bus around the different mountain towns in search of the “big one”. Learned to fly fish when I was 15 years old and really started developing into a serious angler in my mid-20s, learning to guide on foot as a wade-fishing guide, then learning to row a boat to become a drift-boat guide, where I also fell in love with traveling. With my first saltwater trip to Isla Blanca above Cancun, Mexico, I easily fell in love with tarpon fishing in all things saltwater fly fishing. Fly fishing is taking me all over the world. I’ve fished Christmas Island, Hawaii, Mexico, Honduras, Bali, the Bahamas, Belize, the better part of the western United States, Minnesota, Massachusetts, New York, and the best ones are Colorado and New Zealand.

Patrick Sewell

Born and raised on the mean streets of Aspen, my life has been shaped by the mountains and rivers that make my home so special. I fell in love with skiing when I first clicked into a pair of skis at the age of two, and while skiing has been my life’s passion, time spent on the river wether in a kayak, a raft, or more recently a pair of waders or a drift boat has brought balance to winters spent chasing pow. My love for our local rivers and the beautiful fish that swim in them has grown exponentially over the years, and I am now lucky enough to guide for Aspen Trout Guides and share my passion for these fish with those who seek their mysticism and wonder as much as I do. I consider myself one of the luckiest people in the world and I love sharing my home and my passions for skiing and chasing big fish with those who visit this little place called Assspen… Let’s go fishin!
