About Us


Isidro grew up in Mexico on a large ranch. He spent his days farming, training mules, donkeys and horses and raising cattle and goats. As a young man he came to the US and worked for many years at a large breeding farm in Maryland called Winbak Farm. He delivered hundreds of foals a season and broke yearlings and showed them in sales. He became known as the go to guy for all the most difficult horses.  Isidro moved to California and opened Isidro Espinoza Horsemanship LLC with his wife Amber and became a TIP trainer and competes in Extreme Mustang Makeovers and Endurance races. Isidro is also a very accomplished farrier. Isidro has multiple top ten finishes in both the Extreme Mustang Makeovers and AERC Endurance rides with Best Conditioned wins.

About Us


Amber was blessed to grow up with horses thanks to her mother DeAnne's lifelong love of horses. She preferred to ride her pony bareback everywhere. Amber dabbled in local western shows and gymkhanas. She became passionate about jumping and worked hard to learn everything she could and showed all over Southern California in hunter and jumper competitions. She developed a lovely group of students and horses that showed well in Southern California on the Hunter/Jumper circuit. Amber then moved to Maryland and worked at Winbak Farm where she met Isidro. In 2006 she moved back to California to go to nursing school and decided to fulfill a dream and adopt and train a wild mustang. This experience changed her life and she fell in love with the American Mustang. Amber has competed in four Extreme Mustang Makeovers and one of her makeover horses became the first BLM mustang in Finland! Amber is also an approved TIP Trainer with the Mustang Heritage Foundation. She now competes in Extreme Mustang Makeovers, trail trials and endurance rides with Isidro.
