Greg SchubertMr. Schubert graduated from Christian Brothers High School in 1986 and continued his education at St. Mary’s College of California, receiving a Bachelor’s of Science Degree in Business Administration in 1990. While in college, he returned to Sacramento and worked summer jobs for several influential developers including Buzz Oates Companies and Mark III Engineering Contractors. It was this exposure to the real estate development and construction industry that cemented his decision to make construction a career.

After graduating from college, Mr. Schubert returned to Sacramento and started a fifteen year run with Buzz Oates. Starting as a runner, he processed building permits and created marketing profiles for the Real Estate division of Buzz Oates Companies. After one year, his position grew into project management.

The project included adding passenger elevators, adding new windows, rehabilitation of mechanical and electrical systems and overseeing all facets of tenant improvements. Upon completion, he returned to Sacramento and became the Senior Project Manager for Buzz Oates Construction operations. From 1999-2005 he managed new construction, completing distribution centers for Radio Shack, Con Agra Foods and Coca-Cola generating over $80,000,000 in construction revenue each of the five years.

In 2005, Mr. Schubert joined the development team of John Saca and Saca Development. In 2006, Mr. Saca and Mr. Schubert opened Saca Builders, Inc. to self-perform the construction of Lincoln Crossing Marketplace and Folsom Point Shopping Centers as well as turn-key stores for Staples, Petsmart, TJ Maxx, Ross and Walgreens.
