Gabriel Bargas

Our Inspiration

“I founded Bargas as a testament to, and in recognition of, my grandfather Gabriel Bargas. The firm’s name – Bargas –is a testament to, and is in recognition of, my grandfather Gabriel Bargas. For without his guidance, sacrifice and fortitude the Bargas family would not have migrated from Progreso, Mexico to San Francisco. My grandfather left Mexico in the mid-1940’s leaving his wife and six daughters behind until he could save enough money to move his family to join him as soon as possible.

His purpose for coming to the United States was a similar story to many other immigrants; to obtain an education and career that would further the possibilities for his family. From the time of his arrival in the United States to his death in 2010, Gabriel was adamant that his family appreciate the many opportunities provided to them, such as the chances for higher education so that we could share what we have learned with our communities.

During decades of family growth and relative prosperity he continued stressing to his daughters, and his grandchildren, the importance of being self-sufficient through the pursuit of an education and establishing a career. Gabriel instilled in the Bargas family the importance of having a life-long work ethic and purpose and leading one’s life from a place of service.

I miss his guidance and seeing the pride in his face, but I know that his legacy and spirit lives on in Bargas Environmental Consulting.For that I owe him my commitment to continue his journey.”

The project, in the City of Citrus Heights and unincorporated Orangevale, connects several neighborhoods to seven parks, several schools and the Sunrise Marketplace. Bargas staff biologists conducted botanical surveys and then processed data and identified plants found in the field. A post-field data analysis was conducted, as well as a rare plant survey.
