Michael Neff Sr. - CEO

Job Titles:
  • CEO
Don Neff's journey farming tree crops began in the mid-80s when the investment firm he worked for made significant investments in the South Florida Citrus industry. After relocating to Southern California and working on some construction projects, he was given the opportunity to manage the last remnants of Susanna Bixby Bryant's estate in Yorba Linda in 1995. Intrigued at the idea of farming the land as the previous seven generations of his family had, Don took on the orchard as a new project. This twenty-acre orchard was spared from development because of its location in the Santa Ana River flood plain. It features four thousand Valencia Orange trees, many of which were planted in the early 60s. Don Neff comes from a long line of agribusiness pioneers. Dating back to 1728 when Michael Neff Sr. emigrated from Switzerland, the Neff family has a rich history in agriculture spanning eight generations in the US. Originally settling on the East Coast in Lancaster County, Pennsylvania (1744) subsequent generations settled in Wythe County, Virginia (1782), and family descendants thereafter pioneered in Eastern Washington State just after statehood in the late 1800s. The Neff family remains active today in Washington State agribusiness ventures. Don Neff has a rich history in agriculture and farming and he and the Neff Ranch team work hard to preserve the historical citrus production in Orange County. Don's knowledge and experience encompass land evaluation, landscape design, and water-conserving irrigation practices and he and the team take great pride in caring for the groves and being responsible growers.
