Diamond Ventures
Diamond Ventures, Inc. was founded in 1988 by Donald R. Diamond after his Wall Street commodities career and subsequent Arizona real estate activity. His daughter Helaine Levy and grandson Nathan Levy continue involvement in the business following his 2019 death. The firm operates as a single-family office with offices in Tucson and Denver. The firm allocates across residential and commercial real estate, private equity, and growth-oriented operating companies. Asset classes include master-planned communities, industrial and retail properties, and venture investments through DVI Equity Partners formed in 2018. Confirmed positions include Rocking K and Verano in Tucson, Saddleback Heights in Phoenix, The Hills at Buffalo Run in Commerce City, Colorado, and Gravity in Austin, Texas. Geographic reach centers on Arizona with additional activity in Colorado, California, and Texas. Joint ventures with builders such as Dorn Homes, AF Sterling Homes, and LOKAL Homes support residential projects. The team includes seven named principals plus additional professionals in finance, construction, and acquisitions. David Goldstein has held the presidency since inception. William Kelley serves on boards including the Arizona Commerce Authority and Tucson Airport Authority. A 2025 Southern Arizona Government Affairs Breakfast moderated by Priscilla Storm addressed local infrastructure topics with county and city officials. Philanthropic vehicles include Diamond Family Philanthropies and the Banner-Diamond Children’s Medical Center. The structure separates real estate development and private equity through DVI Equity Partners while maintaining direct family oversight via Helaine Levy on strategic decisions. Long-term partnerships with entities such as Rocking K Development Co. and Canada Hills Development Company shape acquisition and entitlement processes across multiple decades.
