In addition to the office building industry, its portfolio includes projects for the industrial, mixed-use/adaptive reuse, retail, education, charter, religious, science, technology, entertainment, historic, housing, and hospitality sectors. Initially, Del Amo only had 10 employees and received about $14 million of revenue annually. With the help of the firm’s president and CEO, Steve Donahue, it now has over 115 employees and takes in about $250 million of revenue annually. This 15% year-over-year growth was generated by the firm’s exceptional people, superior services, and outstanding work. 

The Apollo at Rosecrans is among the most notable projects in the firm’s office portfolio. The team was asked to create a space that would attract creative office tenants. This project developed a stylish, contemporary complex out of five formerly vacant buildings. To start, they tore down large sections of the original tilt-ups to build a cozy patio. After that, building columns were taken out to create an open-floor design. Doing so required an extensive structural renovation. Dramatic canopies at the entryway of new buildings integrate a company identity and welcome guests.
