Marian brings a lifetime of dedication and experience to the clients and the staff. She has seen horses, riders – even the industry – grow and evolve, and has always been involved in shaping the hunter/jumper world in Northern California. For more than 40 years, Marian has worked with young children, juniors, and adult amateurs, focusing on safety, as well as their horsemanship skills. In 2020 she was the recipient of the NorCal Hunter Jumper Association Lifetime Achievement Award & the Wendy Nissen Memorial Trophy Award.
Her teaching philosophy: function follows form. Marian believes in the development of a strong equitation foundation for all of her riders – no matter what ring they will ultimately compete in. She prioritizes the attainment of the fundamental skills that serve riders for success in all riding disciplines for the rest of their riding career. She believes in safety first and a positive attitude when having fun.
Marian has enjoyed great success in discovering and fostering talent in young horses with her European importing business. Through a network of trainers she works with in Belgium, Holland and Germany, she finds prospects to develop under her watchful eye. Her horses are often top 10 in the international Young Jumper Championships and many are competing right now in Grand Prix and Hunter Derbies throughout the United States.
She has participated in all aspects of the equestrian sport, including being named the Chef D’Equipe of the NorCal Spruce Meadows team in 2010. Under her tutelage, her clients have achieved numerous West Coast wins and championships, including some of the most competitive year-end finals in Northern California, PCHA high-score awards, Spruce Meadows wins and Thermal Championships.

From the minute she first rode a horse, Jen fell in love with horseback-riding and knew it was what she wanted to do with her life. She loves teaching others about the joys of riding and is passionate about continuing to learn and perfect her own coaching, riding, and horsemanship skills. As a teenager, Jen competed in hunters and equitation. However after riding a particularly tricky stopper, she realized she had a lot more to learn about the basics of horsemanship and flatwork. So, after completing her degree in Mathematics, Jen spent two years learning natural horsemanship, how to rehabilitate problem horses, and the fundamentals of dressage, ultimately competing Prix St Georges. She then returned to the hunter-jumper world, and in pursuit of learning from some of the best, has been lucky enough to work and ride for World Cup Finalists and a former Olympians. Jen now enjoys applying the skills she's learned to be a contributing team member of MNE, as well as having the opportunity to further develop under Marian, Lauren, and Sue Ellen!
Sue Ellen Wright
Sue Ellen is a long time presence at Riverside, having been involved in training,
showing and importing horses, as well founding the on-property apparel and supply store originally known as The Wright Stuff. A native Californian, Sue Ellen has been riding and competing since childhood. She started out in Western and won numerous championships throughout the state with her wonderful horse “Dear Sir,” culminating in winning the PCHA “A” Stock Seat
Equitation Championship in 1973.
At 14, she made a seamless transition into the Hunter/Jumper discipline and
continued her winning ways with her fantastic horse “Flying Bird.” Collecting blue
ribbons up and down the west coast in hunters and equitation, Sue Ellen qualified
for all the major national medals and competed in the Finals at Harrisburg,
Washington DC and Madison Square Garden.
After her junior riding years she moved to New York and rode with Kris Ward,
McLain Ward’s mother. Sue Ellen laughs at how she used to babysit McLain, now a
three-time Olympic Gold medalist and considered one of the best riders in the
Returning to California, she turned pro and worked for Jimmy Williams and Susan
Hutchinson, then started her own training business in Orange County. She married
in 1986, then had her daughter Shannon before the family moved to Novato. Sue
Ellen began working for Marian Nelson in 1997 and together they’ve had a very
successful partnership, with students winning many championships every year. She and Marian also began importing horses from Europe, one of which “Relance,”
finished in the top four in the West Coast 7-year-old Young Jumper Championships
at Showpark in San Diego.
Several years ago Sue Ellen unfortunately had a very bad accident while loading a
horse into a trailer that nearly cost her her life. After major surgery, rehabilitation
and recovery she is looking forward to returning to Marian Nelson Equestrian and
continuing the winning ways that have been a hallmark of her and her students’
careers. As Sue Ellen likes to say, Coach Wright is back!
