Our Board
The LA Chapter of CDS is led by a volunteer board of directors who help plan and oversee the chapter’s programs and events. Together, the board manages the chapter’s budget, organizes local shows and educational opportunities, coordinates the year-end awards and banquet, and supports member outreach and sponsorship.
Each board member brings their own experience as a rider, professional, or volunteer—and shares a commitment to growing an inclusive, well-run dressage community here in Los Angeles.
