A native of Oakland, she competed as a young woman in riding events at Madison Square Garden. She first met her future husband Robert Genisman at a New Jersey riding academy in 1950 and they rode in competition against each other, "with Nina always winning," says Mr. Genisman.
When her family returned to Oakland, she worked at St. Francis Riding Academy. She and Robert Genisman met again after he completed four years in the U.S. Navy and were married in 1956.
Throughout her life, she worked with horses: teaching, judging, training, mentoring, and directing riding academies, including the direction of the early stages of Spring Down Equestrian Center.
She is survived by her husband, Robert Genisman; children Elizabeth Huber, Linda Belleville and David Genisman; siblings Suzie Mason, William Curley and Judy Ranzer; five grandchildren; and three great-grandchildren.
