Sam Farr tribute
- HON. SAM FARR of California, House of Representatives Friday, November 6, 2009
- Mr. FARR. Madam Speaker, I rise today, with my colleague Anna Eshoo to honor the memory of a great woman and model citizen, Mardi Wormhoudt. Mardi passed away October 21, 2009 in her Santa Cruz home at the age of 72. Mardi was an influential politician, a loving mother and wife, and a dedicated friend.
- Mardi was born October 1, 1937 in Wisconsin. She graduated with honors from California State University at Los Angeles in 1967. During the late 1960's and early 1970's, Mardi worked as a caseworker for the Los Angeles Department of Social Services, as well as a project director for the Martin Luther King Center in Pasadena. During this time, Mardi and her husband Ken, the love of her life, started a family with the birth of their children: Zachary, Jonathon, Jacob and Lisa.
- In the mid 1970's, Mardi moved her family to Santa Cruz and by 1981 she was an elected official. She was soon Santa Cruz County's leading female official. She is best known for her time as Mayor when she helped lead Santa Cruz through the tragic Loma Prieta earthquake. We all remember the iconic image of her briefing President Bush, Representative Panetta, State Senator Mello, Assemblyman Farr against the backdrop of destruction along Pacific Avenue. Mardi helped keep the spirits of citizens high, and encouraged the city to unite in rebuilding efforts. In total, Mardi dedicated twenty-one years to public office. Mardi will also be forever remembered for her dedication to women's rights, environmental protection, and a firm belief in local economic growth. Mardi was also an advocate for those who were marginalized and overlooked.
- Mardi was constantly active in the community as a member of a plethora of groups, including: The Santa Cruz City School District and the Santa Cruz AIDS project. She also received a vast stable of awards, including: The People's Democratic Club Woman of the Year 1988 and the 1991 nomination by then Assemblyman Sam Farr for The California State Assembly Woman of the Year. Those who were close friends of Mardi will especially remember her for her veracity, playful humor, hard-working personality, loyalty, and devotion to family.
- Madam Speaker, we know as co-representatives of Santa Cruz County that we speak for the entire House when we extend our deepest sympathies to her family, and our deepest appreciation for the work she did to make her community and the world a better place.
