​Sierra Southerland is the proud daughter of Kevin and Erin Southerland, and sister to Justin and Garret. She grew up immersed in the western lifestyle and now resides in Longmont, Colorado. She is a Colorado State University alumna, holding a Bachelor of Science in Equine Sciences with a minor in Business Administration and a Master of Science in Animal Sciences specializing in Breeding and Genetics. Her academic journey at CSU included involvement with the CSU Ag Council, Ranch Horse Team, Rodeo Team, and the Legends of Ranching Colt Starting Program, where she cultivated a deeper appreciation for Colorado’s agricultural heritage and the professional sport of rodeo.
From an early age, Sierra developed a passion for connecting with others through her love of horses, agriculture, and advocacy for animal welfare. Growing up in a small horse town, she was surrounded by the western way of life, owning an abundance of animals and spending her youth riding and showing horses. She participated in events ranging from gymkhana, team sorting, barrel racing, and reining to western pleasure, and now enjoys training her personal barrel horses and dabbling in team roping and breakaway. Her experiences competing in the National High School Rodeo Association and holding Rodeo Queen titles in her youth ignited her passion for advocacy and solidified her dedication to representing
the rodeo community.
As Miss Rodeo Colorado 2025, Sierra is dedicated to using her platform, “Clean Genes”, to educate the public on the importance of responsible breeding practices and raising awareness about genetic issues in horses and rodeo livestock. With her background in Breeding and Genetics, she aims to highlight the consequences of
poor breeding practices and advocate for sustainable solutions that ensure the health, longevity, and performance of the animals integral to the rodeo industry.
Her mission is to inspire change and help preserve the traditions of rodeo and the western way of life for future generations.
Whether she is in the arena or engaging with the public, Sierra is passionate about connecting with people, promoting the professional sport of rodeo, and sharing the
values of hard work and community that define Colorado’s rich western heritage.
