An accomplished real estate investment and development company, Cornerstone has owned and managed commercial real estate from Maine to California. The company made the conscious decision to focus on properties in New England and, as our geographic reach became more focused, Cornerstone commenced a series of intensive, ground-up development projects. We often find that the best investments are already in our portfolio. Cornerstone seeks to add value to all of our real estate investments through improvements, renovations, and expansions on assets in attractive locations.
