Find Your Heart Mustang

What is the Heart Mustang Program?

We developed The Heart Mustang program to fill a need. The need was for well trained mustangs who were trained in the timeframe that allowed them to excel and not experience undue stress and trauma. The need for mustangs trained by experienced mustang trainers. The need to match mustangs with their new people. When all these things are in place we have found that mustangs have their best chance to excel in their new homes.

We personally go to the corrals or a storefront and hand pick mustangs for this program. We have extensive experience of selecting mustangs from sifting through thousands upon thousands over the past 14 years of training them. We pick these mustangs based on temperament, type, size, conformation and color. We then spend on average 10-18mths training these horses and cover all their vet, travel, care and much more costs while in the program. The cost of the program is based on those expenses, however, it is much more cost effective than paying for that all separately on your own. Please plan your budget for a horse receiving all this care and training accordingly.

What is a Heart Mustang?

There are two different levels of Heart Mustangs. They must meet all requirements before we are willing to release them to their new homes.

The Foundation Heart Mustang usually takes about 8-12months to train. Some may take a little less and some may take a little more. We do not rush them. Foundation Heart Mustangs will be suitable for an Intermediate-Advance Riders. They are also suitable for first time mustang owners.


The Elite Heart Mustang

The next level of Heart Mustang is the Elite Heart Mustang. Elite Heart Mustangs will be able to safely and confidently do all the Foundation Heart Mustang can do but will be more finished and accomplished in the following:

The Elite Heart Mustang usually takes about 18-24months to train. Elite Heart Mustangs will be suitable for advanced beginners and some may be suitable for beginners and children.

What Makes This Program So Unique:

    Every Heart Mustang will have their journey from wild to ready chronicled via video. You get to watch your heart mustang through the stages of training journey so you really get to know them. Each Heart Mustang will have their own Case Study that you have access to forever.


    Every Heart Mustang will come with a complete health record showing all current vaccines, deworming, current Coggins, and current dental. That way you know they are healthy. If potential buyers would like to have x-rays and PPE, they may at their expense. Heart Mustangs will have their DNA tested to see which are the main breeds in their DNA and you will be provided with a report/certificate of breed(s).


    We will match you to the right Heart Mustang. You will fill out an interest form and we will have an interview to make sure we only recommend the Heart Mustangs that will have the best chance to become your dream horse.


    We understand that budgeting for mustangs of this caliber can be difficult and we are willing to work with you so you can get your dream horse. These are the best of the best and will be priced accordingly. Understand that we want them to have wonderful homes too so are willing to work with you and there are no hidden fees!


    While your Heart Mustang finishes their training you may come to our ranch and get lessons with them. You may also participate in any clinics we do while they are in training at no additional charge (at the location the horse is at).

How Can You Get A Heart Mustang?

Heart Mustangs will be posted to our website with current photos through their training journeys plus on all our social media platforms (Facebook, Instagram, TikTok and YouTube). We will start accepting applications to purchase after they are posted. Clients with deposits on file will get first priority and first right of refusal on all Heart Mustangs before they are posted to the public.


Once you are matched with the Heart Mustang of your dreams, you can choose which training package you want for them. You can choose between the Foundation Heart Mustang program or go all the way and get the Elite Heart Mustang! You also get to make requests of what you would like your mustang to learn that is unique to your needs (within reason).

What Others Have To Say

"I hit the jackpot with my new mare that I purchased from Amber and Isidro. Chancla is such a love and so well trained. Amber has always been there when I had questions regarding feed, tack, and training cues. I finally got to take her on a trail ride after all the rain finally passed. She was so calm that the other horses I was riding with just followed her lead. She continues to impress me on how smart and patient she is. Clear to me that she was trained with patience and love. Thank you, Amber and Isidro, she is perfect for me!" - Tina

"I just picked up the sweetest little filly mustang from Amber & Isidro and truly feel like I won the lottery. This filly is confident, curious and whip smart. She was clearly cared for extremely well during her time at their ranch. She is healthy with a gorgeous coat, mane and tail, and she loves people. The foundation on this filly is rock solid. Amber was easy to work with, responsive, and kind. I highly recommend Isidro Espinoza Horsemanship if you are thinking of adopting a mustang or need training."

- Sharen

"I purchased a mustang from Isidro and Amber in August and I can not say enough positive things about the entire experience. They were both such a pleasure to work with. This was my first time purchasing a horse and they made the experience so pleasant and smooth. They answered all of my questions, usually offering the information to be before I could even ask. They were so helpful in preparing Dante for pick up as well. They did extra trailer training with him in the two weeks prior to me picking up to ensure he would be comfortable as possible on his long drive. Once I got him home and began working with him myself, I could not be more impressed with the foundation they put on this horse. He is so quiet yet willing and responsive to everything that is asked of him. I have to pinch  myself everyday because I can’t believe how lucky I am to have found them. I got exactly the horse I was told I was getting and as a first time buyer I was nervous that would not be the case. I could not be more impressed and thankful for the honesty and authenticity of Isidro and Amber. Dante is everything I have ever dreamed of and I am so grateful to you both for all of the hard work and incredible foundation you put on him!"
