Our Culture
Creating a corporate culture that aligns with OC core values.

Jonathan Ninnis, James Robinson, Michael Sci and John McGrath understand the success of OC starts with the team and is built upon a sense of community and collaboration, which in turn fosters culture.

As Principals of a company that is continually expanding, Jonathan, James, Mike and John regularly work on encouraging the team to have transparent communications and believe that thinking, planning and intelligent decisions are better when colleagues work cooperatively. In creating this cohesive environment, OC created a culture campaign called "Our Culture" TEAMS, or OC TEAMS to remind and encourage the team every day to work within the parameters of being Transparent, Efficient, Adaptable, Methodical and Safe.

OC knows that safety is an integral part of our daily routine.

We have launched the “Safety First, You Never Work Alone” initiative. Our team is committed to ensuring our employees and trade partners return home safely each day to their family and loved ones.

Through our OC TEAMS platform, safety is embedded within our culture and achieved through corporate and principal oversight, regular reporting, and ongoing education and training. We are dedicated to an incident and injury-free workplace and will never allow safety to be sacrificed for production.
