SCS Engineers Celebrates 55 Years of Waste Management and Environmental Services

April 1, 2025

SCS Engineers, the employee-owned environmental consulting and construction firm, celebrates its 55th anniversary!

 

Over the past 55 years, SCS Engineers has established a leadership role in comprehensive solid waste management and environmental services, which would not have been possible without the support of our municipal clients and industry. There were fewer than a handful of engineering firms specializing in environmental consulting when SCS was founded in 1970.

Today, the firm supports a wide range of environmental solutions in different industries and business sectors. Fifty-five years ago, no one could have imagined using drones and satellites to collect information for landfill operations or utilizing carbon sequestration in an environmentally safe manner. CEO Doug Doerr says:

Our greatest reward is client satisfaction. Thanks to you, our clients, SCS Engineers has received numerous awards and industry recognition for its research achievements and technological innovations, which protect human health and the environment while enhancing operational efficiency. We take pride in operating and maintaining critical environmental infrastructure that the public and businesses depend on. Our employee-owners know how to solve problems and, drawing on our deep bench of engineers, scientists, and consultants, move forward as a team.

SCS’s business model features regional and satellite offices situated near client sites, with mobile offices co-located on project sites. “The model has always worked well for us,” President Curtis Jang recently stated. “Our professionals and technicians live nearby; our distributed network means we are nearby project sites instead of flying, or working online.”

“We’re proud of the care and contributions by our colleagues over the years, and now,” states Eddy Smith, COO. “That sense of responsibility and ownership, along with SCS’s camaraderie and high-quality results, brings our clients back.”

 

A History of Excellence and Results

The environmental consulting firm started as a partnership between Bob Stearns, Tom Conrad, and Curt Schmidt on April 1, 1970, in Long Beach, California. The three engineers knew and respected each other’s strengths and capabilities: Stearns was an expert in solid waste, Schmidt was a water and wastewater engineer, and Conrad was a jack-of-all-trades with experience in civil engineering, solid waste, water and wastewater.

SCS Founders
Bob Stearns (C), Tom Conrad (L), and Curt Schmidt (R), three civil engineers with broad backgrounds in the then-new field of environmental engineering, formed SCS in 1970 in Southern California.

By the late 80’s, SCS Engineers had created new specialty practices, under the name SCS Field Services, to perform landfill and landfill gas system construction, operations, monitoring, and maintenance. The firm was proud to offer comprehensive services, but it knew from its experience that each landfill and solid waste operation is unique. SCS OM&M now operates 27,500 LFG extraction wells and supports over 650 landfills across the nation. SCS Field Services Construction is a Class A – General Engineering Contractor with Hazardous Materials Certification. SCS believes that by overlapping design, construction, and operational activities, it has led to the innovations listed as SCS Firsts on their website and saved their clients money.

In 1986, the firm also made a significant and strategic decision to create an employee stock ownership plan. Chairman Jim Walsh explains, “As an ESOP company, our employees own shares in SCS Engineers and all its practices. We felt that ownership inspires better performance and that our staff deserve control in the decision-making and direction of the company. It has proven to be a successful business model for the firm.”

Combining SCS’s expertise in solid waste management, landfills, and regulatory compliance, SCS Energy was created in 2001 to focus on the design and design-build of landfill gas-to-energy (LFGE) systems. SCS now has one of the longest and most successful biogas practices in the United States, primarily in Renewable Natural Gas. SCS designs, constructs, and operates more RNG, LDFE, and DGE facilities than any other environmental engineering firm in the nation.

Growing and expanding its environmental expertise to serve other industries and sectors, SCS draws on specialized practices to continue to support a growing number of public and private clients under the SCS Engineers umbrella.

Forward Focus on Culture and Growth

SCS continues to develop technologies and programs that help clients lower their operating costs and reduce their environmental impact. The technologies and applications used in landfills have found applications in agriculture, heavy industry, manufacturing, and municipal settings. These advances enable the development of more efficient infrastructure and processes, supporting companies in their transition to renewable energy resources while maintaining sustainable practices and minimizing additional expenses for consumers.

SCS is a popular place to work and learn, hiring many young professionals, including these new executives. (L-R) CPO Stacey Dolden, COO Eddy Smith, CFO Steve Liggins, CEO Doug Doerr, CSO Nathan Hamm, President Curtis Jang, CTO Jay Hatho.

SCS clients entrust the firm with managing more than 40 million metric tons of anthropogenic CO2e greenhouse gases annually. The firm collects and beneficially uses or destroys enough methane to offset greenhouse gas (GHG) emissions from more than 8.7 million passenger cars annually. These figures do not include the significant emission reductions achieved through carbon sequestration, waste diversion, recycling, and repurposing waste into useful products, such as Renewable Natural Gas, compost, or supporting municipal programs that donate perfectly edible food to those in need.

“We attribute our success to our loyal clients who entrust us to address the complexities of environmental challenges,” says Nathan Hamm, CSO. “We are proud of our employee-owners who create the technologies, practices, and systems that make a sustainable, positive impact while being economically feasible.”

Over the years, SCS expanded and hired many talented people. They guide the firm, maintaining the founders’ focus on adopting their clients’ environmental challenges as their own and fostering a culture of success for employees by sharing equity ownership. The firm helps clients minimize waste and pollution while providing GHG-lowering carbon capture, monitoring, control, and accounting solutions, as well as sequestration solutions, with a proven ability to mitigate and remediate air, water, and soil pollution.

“SCS’s culture attracts professionals with diverse expertise, enabling the firm to grow organically. It is on track to reach nearly 1,400 employees this year and has achieved year-over-year record-breaking revenues,” says CPO Stacey Dolden. SCS’s core capabilities include solid and hazardous waste management, renewable energy, remediation, and environmental compliance and sustainability, aimed at reducing or preventing GHG emissions. Over the last two decades, the demand for SCS expertise has expanded into various areas, including remote monitoring and control technology, wastewater and water reuse, composting, sustainable materials management, industrial health and safety, and risk management planning. The firm maintains a deep technical bench, a wide range of industry experts, and extensive knowledge of federal, state, and local environmental regulatory systems, which enables clients to shorten project timelines, control costs, and meet evolving regulations.

 

How is SCS Celebrating 55?

Earth Day is also celebrating its 55th Anniversary this year – the first Earth Day took place just a few weeks after the start of SCS. We’ll be at Earth Day events around the country serving hundreds of communities, charities, and associations. We hope to see you there! SCS Engineers remains passionate about continuing to provide superior client service and solving the environmental challenges of the 21st Century.
