Amanda Gelderman developed a love for the equestrian world at an early age. She grew up on a horse farm in Poulsbo, Washington where she learned to ride in several disciplines, and discovered her true passion in the hunter/jumper world. She showed all throughout elementary and high school on her personal horses, as well as intermittently catch riding for local horse owners.

Upon graduating from high school, Amanda became a working student for Josh and Keeley Stranahan at Winterchill Farm in Port Townsend, Washington where she was able to learn management skills as well as teaching and riding skills. Her next training and coaching chapter opened as a student at the University of Montana Western. During her sophomore year, Amanda became the hunt seat equitation coach of the varsity equestrian team and held that position until graduation in 2012. While she was coach, the team won the region twice and Amanda was the highest ranked rider in the region for 3 years. She won both Regionals and Zones multiple times in the Open divisions. This gave her the honor of representing the region at IHSA Nationals, twice at the Kentucky Horse Park and once in Raleigh, NC.

She spent summers back home at Sandamar where she ran summer camps, judged local schooling shows, worked as assistant to the head trainer, and competed in the 1.20m jumpers. In March of 2013, she became Sandamar’s head trainer. That summer, Amanda took the show team to numerous shows in Washington State and competed through the 1.30m jumpers. In the fall of 2013 Amanda was honored to give a two-day clinic to the University of Washington Equestrian Team with 18 riders participating.

Under Amanda’s supervision, Sandamar Farm had an incredible show season in 2014.  Many of Amanda’s students brought home Championships and Reserve Championships both in the United States and Canada.

Amanda believes in the importance of continued learning and the development of skills as both a trainer and student. She plans to continue showing and taking her students to A circuit shows along the West Coast. Her short term goals are to learn from top trainers in the area and continue her own education to better train her clients and horses. In the near future Amanda is hoping to expand the Sandamar show team and establish herself as an asset to the industry. She is passionate about becoming involved in the USHJA and is looking forward to this new chapter in her career.
