The horse is a strange paradox of strength and acquiescence — and this presents profound challenges for those with responsibility for their welfare. Paramount in this obligation are owners, breeders, trainers and veterinarians. Our team combines expert veterinary knowledge with the passion of lifelong horse owners.

Kristie Morris

Customer Service

Kristie Morris was smitten by horses early but didn’t start riding until 12 yrs old. She bought her first horse when 15. As a young adult she started a long, enjoyable and productive relationship with the Walker family of Marena Stud. This has given Kristie both great pleasure and an increased knowledge of all aspects of a working stud, riding academy and high level competition. From first conception right through to raising, training, schooling, competition, retirement, stud duties and aged care, Kristie has followed many individual horses through this journey with Maureen, Bruce and Lindy Walker. She currently owns two Marena bred horses and continues to work and learn from the Walkers, now into her 16th year.

In 2004 Kristie completed a certificate 4 in equine nursing and is currently studying a bachelor of agriculture, majoring in animal production through the University of New England, NSW.

Dr Stewart asked Kristie to join the Jenquine team in 2013. As a horse owner Kristie is able to relate to the troubles and stresses that come when striving to keep our horses’ health and welfare balanced. Kristie enjoys being able to help fellow horse owners create happy, healthier horses.


Amy Luxford


Amy Luxford is leading a life rich with horses. Born into a family heavily associated with horses across a vast array of disciplines and working lifestyles, it is firmly ‘in the blood.’ Beginning her riding career like most, attending a local Pony Club with ex-racehorses during her childhood growing up in Victoria, Amy transitioned down a different path upon moving to Central Queensland in 2013, discovering a deep and new love for fast spins, big stops and snappy cowhorses.

Along with her Station-bred Quarter Horse mare and Jack Russell Terrier, Amy has recently made some new career and residential leaps, from the Springsure region as a station hand, to settle in the North Burnett Region at Gayndah, in order to pursue her passion in the animal and equine health industry.

Prior to her time spent as a station hand, Amy had a leading role in a large feed and rural supplies store in Moranbah, Queensland, and was given many great learning opportunities to extend her knowledge across equine and domestic animal health products, offering clients and their beloved horses and pets the best possible nutrition available on the market. Very quickly Amy identified a lack of current, up-to-date clinical understanding of NSH (“Bighead is a dirty word!”) amongst clientele, friends and family. Having seen first-hand countless hard-working station horses retire prematurely from their jobs, and performance horses suffer silently through the insidious symptoms of NSH, it is Amy’s goal to change how the disease is perceived amongst horse owners and professionals, so that all equines living on oxalate pasture can receive the nutrition, care and treatment they deserve.
