What do our customers have to say about us?

Como, CO

Tim Glomb

"I have been on trips with Nate, Matt and Josh several times. We've crushed trophy, pike trophy trout, and even had some fun one summer bowfishing for carp. I get my walleye fix down in the metro area on Chatfield with Nate every spring and every fall. Can't wait to get on the water again with them."

Denver, CO

Matt Mockus

I've fished for walleye for years in the midwest so when I landed in Colorado I wanted to see what the opportunities were.  Man did Nate show us some epic fishing at Chatfield Res.  I've been back for several trips and always a great time.  Learned a lot about fishing for them in reservoirs. 

Conifer, CO

Elisa D.

I wasn't sure if fishing was my thing but the first trip was awesome.  These guys are so helpful and made it a great time.  I've been back for a few trips and started fishing more on my own now. 

Oklahoma City, OK

Jeff Tanksley

Met up with Dustin for a day of Northern Pike fishing.  The day started out cold but warmed up quickly.  The lake and surrounding scenery were absolutely beautiful.  When I booked the trip, I told Dustin I was looking for that trophy fish.  He warned me that it would be a grind and he wasn’t kidding.  Take my word for it, you will work your butt off casting to the point of feeling like your arm will fall off.  We caught a small Pike and a few pan sized trout.
