Hi, my name is Trevor Siems. I’m in the Pinedale Livestock 4-H club. I enjoy halter breaking, training, growing and selling beef. I love playing with my brother and building things out of Legos. I am glad that there are so many people who are willing to support our 4-H members and I strive to be a good example to those members who are looking up to me.

*** I want to let you know a little more about the sale on July 25, 2026 @ 1:30:

  1. You can request to split an animal between buyers; the cost can be divided also.

  2. Transportation is already arranged for whichever processor you choose.

  3. If you’re not after an animal, but still want to support Sublette youth, I’d like to share a little about the add-on option at the fair. You can specify a set dollar amount or a % of the sale price on an animal for a 4-H or FFA member, a group, or everyone who participates in the Jr. Livestock Sale. All contributions are tax deductible!

***If you get the chance, come to one of the livestock shows, you’ll see me showing my stock Wednesday, July 22 @ 5:30 pm, Thursday, July 23 @ 5:00 pm, Friday, July 24 @ 9:00 am, and on Saturday, July 25 @ 9:00 am. See you at the fair!

This is my steer Odie. He is friendly and halter broke. He is a black angus. I will be selling him at the Sublette Co. Fair Jr. Livestock Sale. I would appreciate it if you would come and support the 4-H.

Gilligan was my steer in 2025. He was a black angus/Hereford cross, and he won first place in the Hereford ultrasound contest. Thank you to my buyer: Pure West who donated my steer.

It was a lot of fun to be able to show Chipper at the fair in 2024 after missing the year before with Zeb. Thank you to Pure West for buying and donating my steer.

Zeb was unlucky and got kidney stones. He died before I got to show him at fair. Nikki Marincic-Weaver, DVM. helped us do a necropsy on Zeb to learn why he died. I made a poster which won 2nd place overall at the 2023 Wyoming State Fair!

Dodger was my first 4-H steer in 2022. We both learned a lot together. Thank you to Kristi Jones with Western Winds for buying Dodger, I hope you enjoyed him!
