She was involved in various activities in San Francisco, such as a docent for the SF Fine Arts Museums, and worked tirelessly for the San Francisco Chapter of Aid To Retarded Citizens. In 1960, she and her husband bought Middlefield Farm in Novato. It was in her mid-fifties, with one horse and one trainer, that she started the enterprise that would become Middlefield Morgans. It was dedicated to breeding, showing, and promoting America's breed, the Morgan Horse. Thirty years later, she became so successful, that she was known to have the finest string of Morgans on the West Coast. In 1995, she was inducted into the Morgan Horse Hall of Fame in Vermont.
She supported a number of charitable causes including several major new facilities at the Novato Community Hospital, Cutaneous Lymphoma Research at Stanford, her grand children's schools and the Novato Youth Center.
Throughout her life she showed remarkable pioneering spirit, the will to overcome and a strong devoted support to her family. She was always a lady and maintained her sense of humor to the very end.
She is survived by two of her children Peter (Ginnie), and Margaret "Peggy" Haas; four grandchildren, Jennifer(Christian), Dan, Bradley(Kira),and Nicholas Haas, as well as five great-grandchildren, Maya and Tobin Haas -Dehejia, Lilly Hill and Preston and Alaina Haas. She was predeceased by her son Michael Stern Haas and her daughter-in-law Joanne C Haas.
