We are West Yost

30 Years of Service to our Communities

We believe as an organization, that our leadership is here to support our consultants and our clients. This gives the West Yost team a unified purpose and creates a place to support our remarkable team. When we asked our West Yost team how to best mark the occasion of our 30th anniversary, we received an overwhelming response in favor of contributing to local food banks. This commitment to helping out our local communities speaks to the dedication and desire our team has in making a difference where we live and work. Here are the organizations we have supported this year:

We Have Fun!

Office activities

We enjoy celebrations in appreciation of our team throughout the year. For example, we treated our team to #TakeoutTuesday in the comfort of their own homes, in support of the high-quality products we deliver daily to our clients.

We host annual events such as our Annual All Staff meeting which concludes with our Duck Dinner which is a nod to our founders Bruce West and Jim Yost (who decided to form the firm while duck hunting).

We Strive to Become our Best

Greg Smith, Senior Technical Specialist I on the OTCR team, received his PE License while at West Yost

I love my job. It is both challenging and collaborative. I am so thankful to my West Yost colleagues for their support to set up a location in our office that served as a study area. This area provided the quiet time I needed to prepare for my PE exam and attend my online review courses. The supportive culture within West Yost has allowed me to maintain family commitments while working towards my professional goals, including acquiring my Professional Engineering license.

We Do What’s Right
We See the Bigger Picture

West Yost has worked with several clients to evaluate their projects through the Envision Framework rating process and were successful in obtaining LEED Silver certification for a $90M wastewater treatment plant upgrade project for the City of Davis, California.

Environmental Impact

Reduce, Reuse, Recycle and Conserve

To minimize water waste and eliminate single-use plastics, West Yost provides reusable water bottles and mugs, equip offices with filtered water systems and reusable or compostable kitchenware, and install low-flow toilets. Toxic cleaners are minimized to lessen environmental impact. Paper use is reduced through electronic document management, and recycling is promoted for various materials.

Composting and Local Office Sustainability Measures

Each office is equipped with composting bins and instructions to reduce landfill food waste. West Yost facilitates the recycling of e-waste, batteries, and coffee pods. Energy-efficient appliances, motion sensors for lights, and programmed HVAC systems help reduce energy use. We support sustainable commuting options, remote work to cut down on travel, and place offices strategically to minimize commute distances. All staff use VPN-enabled laptops for efficient remote collaboration, significantly reducing our carbon footprint.
