excellence beyond the reins.

"I strive to build a better broke horse that is light in the reins, moves off your leg, and stops from your seat. I know your colts are your investment. I can promise you I’ll give them the education and care they need to succeed in the show pen and on the ranch.”

-Brianna Dorantes.

"horsemen can do very little to teach the horse. What we can do is to create an environmentwhich he can learn."

- Monty Roberts


I pull from the techniques of Buck Brannaman, Clinton Anderson, and Andrea Fappani. I have a disciplined colt starting program that educates unbroke horses from the ground up. All colts must pick up their feet, tie, and haul prior to arriving. I really enjoy advancing horses in specialized training for ranch riding, reining, cow work, ranch trail, and conformation. I also offer consignments that cover sale prep, advertising, and buyer communications for a smooth transaction.

Who i am

I grew up in the high desert and enjoyed many summer nights barrel racing and riding my horses through the sand wash. I owe much of my experience to my mother, Cynthia, who trained horses for two vaquero style cowboys.

In 2019, I moved to Montana and attended Rocky Mountain College. I earned a Bachelor's Degree in Biology and studied equine reproduction, nutrition, conformation and preventive medicine.

I later worked as an veterinary assistant for Montana Equine, then spent time at Bond Ranch to develop my knowledge of reined cowhorses. I finally opened my business in 2022.

I sent my 2 year old to be started. After I got him back from only 30 days I felt confident enough to crawl on him and do a short ride, needless to say no drama!

I sent my 3yr old to Brianna to be started and work on some behavioral problems for 60 days and I couldn't be happier with the results!

– Katie B.

Brianna did a great job starting my filly! She rode her well and my filly was relaxed and confident the whole time!

– Carrie D.

When it comes to reliability and great horsemanship, Brianna and her skills are the one to trust.

– Isaac S.

She doesn’t cowboy them and adds some buttons as soon as they are ready! She has a huge work ethic and shows up!

– Mandy B.

Bri completed a spring tune up on my 4 year old and in only 30 days he was faster and much softer. Well done and thank you!

– Cameron R.

I sent a little 2 year old to her in May and she put an amazing start on her. She didn’t skip any steps and made sure the job was well done.

– Madi R.

She had my spooky mare crossing water and dragging a tarp. All of my future colts will be started by Bri. I highly recommend her.

– Misty H.

Bri started our 3yo, Kaddilak Jack, and he is now such a gentleman. He is so easy to ride! We are very grateful for the time and energy Bri put into him.
