About Sinead

Sinead’s love of horses started at a young age in a small town called Irmo, just outside of Columbia, South Carolina.

“Horses are in her blood,” says her mother and greatest supporter Bernadette Cogdell. “Growing up in Galway, Ireland, our ponies were allowed into the house for tea in the evenings. So when Sinead said, ‘I want a pony for Christmas!’ the request was taken a little more seriously!”

And so it began. The school year was spent riding and taking care of horses at the family farm in South Carolina. By the time high school came around, Sinead spent her summers in Middleburg, VA working for–and training with–Canadian Olympian, Stuart Black.

Under the tutelage of Stuart Black, Sinead achieved an impressive amount as a young rider, including making her Three Star debut at the age of 19 on her horse, Killian. During that competition, she caught the eye of legends David O'Connor and Mark Phillips by being one of only 10 horse and rider combinations to have no jumping or time faults on the championship level course, something that set up her move to the next level.

Sinead topped off her experience with Stuart by winning the Bromont International Three Day Event in Quebec, Canada. She left Black’s barn with enhanced skills and a strong work ethic that would separate her from most in the sport.

That earlier meeting with O’Connor led Sinead to High Acre, home to the O’Connor Equestrian Team (OCET). Her experience as part of one of the most prestigious eventing teams in the world is one she still regards with great respect and appreciation. Under the watchful eye of David and Karen O’Connor, both US Olympians, Sinead was transformed from a kid with blind ambition to an educated and passionate professional.

Thanks to the support of Sinead’s sponsors and owners, she was given the opportunity to move to the UK and train with the legends of eventing. Sinead spent six months with Sandy and Mark Phillips, riding for British team member and European Champion, Zara Phillips. Her positive introduction to European eventing left Sinead craving more.

After meeting William Fox-Pitt at Burghley Horse Trials, he offered Sinead the opportunity to head to southern England. During that time, Carrig LLC purchased her present upper level mount, Manoir De Carneville in Cherbourg, France.

Sinead and Manoir De Carneville finished 2010 with a spot on the silver medal winning team at the Nations Cup in Holland. They then kicked off 2011 with a win at the Advanced at Southern Pines and carried in to Win the CCI**** National Championships at Rolex Kentucky, finishing 3rd Internationally. Sinead and Tate also finished in the top 15 at the 2011 Land Rover Burghley Horse Trials. In 2012 Sinead and Tate were first alternates for the 2012 London Olympic Games.

Since 2012, Tate and Sinead have continued their success together as the only combination named to the USEF world Training list in 2013. 2014 has been another great year as well with the pair winning the CIC3* division at the Fork before finishing 4th at the Rolex Kentucky CCI4*.

Sinead and Tate have been named to the 2014 WEG (World Equestrian Games) Team in Normandy, France.

Sinead has been proudly sponsored by Mountain Horse since 2011.

My "can't live without" Mountain Horse product

I would find it really hard to live without my Mountain Horse riding boots, they meet all my needs! They keep me warm in the off season, looking great and comfortable while teaching clinics and they go right into the ring as a sleek professional boot for showing. Although with that said, the sometimes unpredictable weather I face up north and while traveling, I would be extremely unhappy to give up any of my Mountain Horse winter wear!

Something you might not know about Sinead

I grew up in a small town called Irmo, South Carolina, and although I live in NJ I am truly a southern girl!

Non-Equestrian Accomplishments

The best thing I have done outside the horse industry is to manage to convince one of the best guys in the world to marry me - Tik Maynard!

Memorable sporting achievement

Winning the National Championships on American soil at the Rolex Kentucky Three Day Event. Leading at Burghley 4-star.

Whacky superstitions or traditions

I always have to walk my last cross country walk alone, and I always have to jump with a neck strap no matter how good the horse!
