The culture at KJ is based on trust, growth, and respect.


  • To our clients, we deliver value-added, innovative engineering and scientific services to achieve their goals.
  • To our employees/owners, we provide a supportive, team-oriented environment that is personally and professionally rewarding.
  • To our communities, we give the expertise, experience, and actions that result in a social benefit.

Still independently operated and employee-owned, KJ has demonstrated the integrity that, when paired with expertise, earns powerful loyalty.


Core Values Graphic

At KJ our values define how we do our work and have remained consistent for over a century. As an employee-owned company, servicing our clients well and creating excellence in the projects to which we are entrusted, matters to each one of us.


Service to our clients and to our communities is at the core of our organization. It began with Clyde C. Kennedy in 1919, when he began serving clients in San Francisco. Our personal client service is a value that has remained steady since our inception and it is what differentiates KJ from other firms in the marketplace.


We work daily to make our planet a better place. Whether it is creating a new water supply for a disadvantaged community or helping an industrial client clean up a contaminated site, our purpose inspires all of us. We get to work with our clients to save our planet every day.


We understand that our success is based on dedicated professional relationships and a shared vision and empathy with our clients to fully understand their objectives and expectations that define success. More than 90% of our work consists of repeat business with existing clients, and we have operated this way from the beginning.
