Marissa has been hooked on Mustangs ever since she was 12yrs old when she competed in her very first Mustang 100 DayTIP Challenge at the “Mustang Yearlings Washington Youth” (MYWY) competition with “Stardust,” a white BLM Mustang from the WarmSprings HMA in Oregon, winning 3rd in the Youth Division.

• In 2021, She competed in-hand with a brown yearling filly named “Elsie” from the Paisley Desert HMA in Oregon, winning 3rd at MYWY.
• In 2022, she competed in the Riding Division at MYWY with another brown mare named “Freesia” from the Paisley Desert HMA in Oregon, winning 2nd place.

Marissa has had a special interest in trick training, bridle-less riding and working at liberty with her Mustangs, and dreams of having an all-Mustang liberty team one day. Marissa’s riding aspirations are to compete at a high level in 3 day eventing…but on a Mustang. Currently, she has two “sport-type” Mustangs, “Stardust” and “Freesia,” that she is developing for eventing and plans to start hitting the show arena this summer. Marissa has also halter broke, started under saddle and re-trained many different breeds of horses and ponies including OTTBs and is always game for a challenge. Marissa’s ideal horse is a spicy, brown, mare which pretty much sums up the type of person Marissa is …in that she finds the positives and sees the potential in very spirited, difficult horses full of attitude and personality that most people would pass on and is willing to put the time in to make them great.

Sierra has loved horses as long as she can remember and especially enjoys the pressure of competing. Sierra has tried out several different competitions and loves trying something new.

• In 2019, she competed in the AQHA Young Horse Development Program with a weanling from KT Ranch named KT Alaskan Ruby( “Alaska.”)
• 2020 involved training a wild burro (“Crumpet”) for a 100 day training challenge(MYWY) winning 1st and competing in an AQHA National Horse Judging competition, winning 3rd.
• In 2021, she competed in two Mustang training Challenges, one in-hand (“Paisley”) winning 1st for MYWY in Washington, the second under-saddle (“Dandy Andy”) winning 3rd in the Teens and Oregon Mustangs(TAOM) challenge in Oregon.
• 2022, she trained 3 Mustangs for 100 day training challenges, 1 in-hand-“Shania” winning 1st for MYWY and 2 riding Mustangs, “Peachy Keen” winning 1st for MYWY and “Just Peachy” winning 2nd for the TAOM. She, also, joined USPonyClub, started retraining a fresh off-the-track Thoroughbred (“Alex”) and committed to lessons in Dressage and jumping 2x week.

Sierra loves the process of developing a young horse and building a solid foundation. When not on a horse, Sierra is either working on the family farm, uploading new content to social media or making a to-do list of everything that needs to be done.

Eliza is the youngest of the family but don’t let her age fool you- she already is a very active horse girl. From training wild Mustangs to jumping at Pony Club, Eliza is always ready to tackle a new challenge!
