Equine Health Science is not a faceless multi-national corporation. EHS is a sport horse focused service, run by real horse people with a lifetime's experience in the industry. 

Founder and Managing Director of EHS, Seumas Marwood, has been competing up to 4 Star level in eventing for over 30 years. As a young rider he had a long and successful association with Pony Club, including as a member of the Australian Inter-Pacific team that travelled to Canada in 1981. Over the years Seumas has had three horses on senior Australian squads, and still competes actively in showjumping and one, two & three day Eventing. 

Seumas also has experience in governance, and was the Riders Representative on Equestrian Australia's National Eventing Committee from 1997 until 2004. Following on from that, beginning in 2004 until 2008, he was an Olympic Selector for eventing and was then Chairman of Selectors for eventing until 2012.  


In 2006 Seumas gained his TB Trainers Licence to gain a better appreciation of the racing industry and trained a winner with his 2nd start.

Dani Marwood has also made horses her life. She has evented, show jumped and competed in dressage since childhood, and is an experienced stud manager and qualified AI Technician. In the past, Dani has won the Lakes & Craters 2* Three Day Event, placed at Oaklands 3* on Bumble Bee, and placed 2nd at the Naracoorte Three Day Event and 5th at Melbourne Three Day Event on Zoom.

Both Seumas and Dani have shared the frustrations of many riders who know their horses could benefit from certain supplements, but the high cost of many of these simply put them beyond reach. They decided to use their knowledge of what performance horses really need, and what riders and trainers really want, to bring products like Shark Net, Hush and Complete Hoof & Coat Care.


'We all want our horses to last, especially the good ones. That is why I value the Shark Net Formula to help with the long term protection of their joints. Miss Andretti is no doubt one of the finest racehorses in the world. I am confident that the joint care offered by Shark Net has helped look after her joints long term'

— Lee Freedman, Trainer 2007 Australian Champion Racehorse of the Year, Miss Andretti
