Fly Fishing Guide | Sun Valley Idaho | Silver Creek Outfitters | Sean Sullivan

Certified Casting Instructor

Known for catching the perfect wave, both in the boat or while surfing

“I do like to guide first-time fisherman, though. Catching that first fish is a huge deal whether you’re six years old or 60.”

Sean Sullivan hails from a big family. He grew up the son of a Navy man, so he and his five brothers and two sisters moved a lot and learned to adapt to many new environments. He came to Sun Valley to fish and to snowboard and plans to stay a long, long while. He is an exceptional snowboarder and loves the big extreme terrain of Alaska.

He is also an avid surfer and has traveled the world in search of the perfect wave. Some of the best have been in the South Pacific, Indonesia, Central America and Kauai. Sully also loves to fish. His favorite way to end a day on the river? Fish until it’s so dark you can no longer see to tie on your fly or read the label of the beer you are drinking.

Shawn E. Caine

Sean made sure I was properly accommodated for all my limited abilities. As usual, Sean provided excellent service as a guide and a friend.

Danny Kemper

They [Sean and Guy] were both highly knowledgeable and just great guys. As we say in Minnesota, "They're good People!" I found what I was looking for at my skill level, I learned quite a bit about fly fishing and that's what I was looking for.

Rick Flynn

Sully is the best guide. So excited when you catch a fish.

Fred Hartzman

Sean could not have been better. We had a killer day on the Lost, and he was awesome.

Mark Eshman

Sean is an excellent, patient guide and a very nice guy. I would use him again and recommend him to others.


Sean is awesome! Put my entire family on excellent fishing.

Brett Gentry

My first cast proved fruitful with a fish on my fly and an exciting few minutes bringing it in. Got the adrenaline pumping thanks to Sean! I learned so much from Sean Sullivan in that day. I had heard great things about his ability and it was all true. He is knowledgeable, patient, flexible, very personable and made me feel as though our day on the creek was as important to him as it was for me. He made me feel comfortable and was so prepared and organized we were able to maximize every minute of the day. He inspired me to continue to work on my casting technique and the sport of fly fishing in general. An overall special experience and guide.

Sully is the best guide. So excited when you catch a fish.

Fred Hartzman

This is our second year with Sully, and with 20 years of experience with fishing guides, Sully is at the top. We truly feel like we are fishing with a friend, a teacher, a cheerleader, and someone who truly loves what he is doing. Especially this year with the tough water conditions, he worked extra hard to put us in the best possible position to catch fish and have a great and safe time together. We enjoyed each moment with him and look forward to booking him in the future.


Highlight of my day was seeing the guide interact and teach my 11yr old during a float on Silver Creek. They worked great together! Sully was fantastic and taught me a tremendous amount including nymphing with a high stick and fishing the bugger. The key for me was the friendliness, teaching ability and patience of the guide. Sully hit all these.


Caught some great fish. More important Sean took extra time with both of us and made it a special day.


Sean Sullivan. Fantastic guide, friendly and helpful. Worked very hard to get us to the right spots, provide guide assistance and training, patient and thoughtful. We had a great time and would recommend Sean to anyone. He exceeded my expectations on all levels.

Very thorough and thoughtful preparation, made sure he knew our skill level and needs, and pre-planned spots, as well as adjusted to our time frame and hope to get onto the river. Highlight was catching the largest trout of my life and landing it. Sean was fantastic, as this was a big fish and challenging to land, but he guided me through it. I’d like to share the picture with you both if you would send me the email’s.

I’ve not fly fished before, usually been spin casting on high lakes in Oregon, or on rivers. I’ve always wanted to learn to fly fish, and Sean exceeded all our expectations.

I’ve said it above, but Sean was excellent as a guide, teacher and expert in assisting in our skill and learning, as well as heightening our passion for fishing. We’ll be back and recommend your shop and Sean to everyone we talk to. Since I have a great picture, it will be shown around quite a bit.
