Arnel Development Co

Arnel Development Co traces its origins to George Argyros and co-founder Kenneth Alfred Nelson. The principals developed a real estate business centered on Southern California assets that later became the core of the family office. The firm invests in real estate through direct development and acquisitions. Asset classes include multifamily housing and commercial properties. It has executed projects such as Arnel Plaza in Costa Mesa and maintains exposure across North America. Confirmed investment stages cover buyout, development, and growth. The team includes family members Stephanie Argyros, Lisa Argyros, and George Argyros Jr. alongside operating executives. The Argyros Family Foundation serves as the primary philanthropic vehicle. No verifiable operational events from the last 24 months appear in available records. The office structure ties investment decisions directly to the founding family branch, with board roles at institutions such as Chapman University and Caltech held by George Argyros providing external governance exposure.
