Executive Team

  • John David Arnold, CEO & Founder

    In 1967, while working for the Head Start Program, Dr. Arnold wrote the first PPEP, Inc. grant proposal submitted to the Tucson War on Poverty Program, which was initiated by the Presidents Kennedy/Johnson Administrations.  The initial funding was for $19,000, from which he bought a 48 passenger 1957 Chevrolet school bus known as “La Tortuga” (the tortoise).  Dr. Arnold was the driver, mechanic and school teacher imparting practical educational teachings to help the Bracero farmworkers prepare themselves to be productive in our society.  Having lived in Mexico, he understood first-hand what it was to live and study in an unfamiliar society with a different language and culture.

    From PPEP’s humble beginnings aboard La Tortuga 49 years ago, Dr. Arnold, the PPEP Board of Directors and dedicated staff have sought to carry out the dreams to “improve the quality of life” of the farmworkers and rural poor whom visited the bus in those formative years.  His work has been cited as national models 10 times in U.S. Congressional Records, including citations by U.S. Congressmen Udall, Kolbe, Pastor, Grijalva, Giffords, and Senators: DeConcini, McCain, Kyl and Enzi of Wyoming. His programs have been honored twice at the White House, among numerous other recognitions nationally and internationally.  US Congressman, Ed Pastor wrote “It is your vision and energy that transformed ‘La Tortuga’ into a major force for ‘Improving the quality of life in Arizona and the world”.  US Senator, Mike Enzi wrote, “you may be the most innovative person I know.  It’s always fascinating to learn of your new and intriguing advances, plus being a voice for the migrant farmworker and their kids.”  Senator McCain stated “Ultimately much of our future depends on programs such as PPEP” www.ppep.org.
