Making Fly Fishing Accessible

They're all "Lucky Flies" when you have a biologist in your fly box.

As seen on Denver Channel 9 News in Catching Colorado

Founded by Aquatic Biologist & Restoration Ecologist Peter Stitcher, Ascent Fly Fishing strives to provide a fish-eye-view of the hatch and knowledge on how best to fish it. With every tie and every fly box packed, our goal is to answer the universal questions of the fly angler:




While building trophy trout water and restoring rivers across the US, Peter would regularly be sampling invertebrates to assess the health of a fishery and to determine what needed to be done to grow larger, more vigorous trout.   Based on this experience, an exhaustive invertebrate database (really big list of bugs!), and a fly catalog of more than 200,000 flies, we are now putting that science to work for fly fishermen and women across the globe!

No longer is success on the water the exclusive privilege of fishing guides and the inner circle of the fishing elite! Done are the days of fishing blind on the river, ignorant of which pattern to tie on!


At Ascent Fly Fishing, our passion and drive is to make both the science and cost of fly fishing accessible to all, with expertly-tied patterns and selections that match the lifestages of the bugs on the waters you fish, when you fish them.

Join Ascent Fly Fishing on Mission:



We put our money where the fish's mouth is!

Ascent Fly Fishing is a proud supporter and business parter of Trout Unlimited.  Their mission to conserve and restore the cold water habitats that are home to trout, greyling, and salmon is essential for the future of these species and the sport of fly fishing which we all love!  We encourage each of you to join with us and Trout Unlimited in the support of conserving trout waters.  We're happy to go the extra mile, and offer every client who places an order of $50 or more a free, year-long membership with Trout Unlimited!




The men and women of our armed forces constantly put their health, lives, and emotional well being on the line to preserve and protect our nation and freedom.  This commitment often leaves physical, mental, and emotion scars, and Ascent Fly Fishing is proud to support Project Healing Waters in their effort to provide a safe place of healing on the water for active military personnel and vets.  Supplying flies, gear, and space at the Fly Fishing Rendezvous for Project Healing Waters is the least that we can do at Ascent Fly Fishing. 

Thank you to our troops for all you do!



Rett Syndrome is a neurological disorder that affects young girls mostly with loss of speech and motor control, severely disrupted breathing and eating, skeletal deformities, physical seizures, and tremendous emotional duress.  Rett presents many challenges to those children directly affected and their families. Fortunately they receive love, therapy and assistance through the The Rett Clinic at the Children’s Hospital of Colorado.  Risers 4 Rett was started and run by several long time clients of Ascent Fly Fishing.  As parents and a family who have also benefitted from the care of the folks at Children's Hospital, we are honored to be counted among many other fly fishing brands who support and sponsor Risers 4 Rett and their mission to fund medical advances, and provide better care for these girls.
