Working on highly technical projects requires design teams to develop various solutions and sometimes need them to be in a hurry. Syska Hennessy Group provides accessible solutions. The National Engineering Firm has five California offices and 110 more employees in the State.
“The key to us is that we have a relationship with the senior management of the firm and that they meet our needs,” says RMW Architecture and Interiors President of Stank Stan Lew. “Getting sensitive solutions to our clients is key and always a partner.
John Passanante, executive director of Syska Hennessy, accredits the strategic vision of the 2025 firm, formulated ten years ago, and his employees. “We didn’t want to be a single type of company,” he says. “We want to create relationships with customers, incorporate in them, understand their business in order to work with solutions with them and achieve their business repeated.”
To better differentiate the firm, Passanante says it made it a point of thought, ready to reach the table soon with customers to present various solutions and then focus on creating relationships while delving into the firm experience.
So far, this strategy has pushed for continued growth in the West, where a diversity of sector expertise has seen Syska Hennessy a critical mission approach to data centers as it continues to grow in criminal aviation and justice. The firm recorded income of $ 29.15 million in the west region by 2024, an increase of 11%.
The company’s experienced business strategy, the background line and the history of strong customer relationships have obtained at Syska Hennessy Group Enr West Firm of the Year Honors.

Force through specialization
Sean Marcel, Syska Hennessy Principal, says that the firm’s ability to focus on so many sectors and develop experience on a highly technical and oversized scale is partly linked to a strategic approach in creating a practice with leaders in the sector instead of regions. This strategy guarantees that each office does not work in a silo and knowledge is shared in the offices.
The data from the data center has encouraged the modern Syska Hennessy focus, working with customers in the planning and location process before designing. As customers seek more work, Marcel says Syska has trained teams to support this. Passanante says that the development of expertise in the offices allows them to support projects, regardless of where they are, and doing the job from anywhere.

“Being able to select teams and working in various offices has done very well,” says Marcel.
Lew says his 15 -year relationship with Syska has continued to grow from small projects to fashions to significant scale billionaire projects. A recent project in the world of “flying vehicles” included a battery research laboratory, a research and development testing center and an engineering headquarters, all in California. Allowed the two companies to meet in a new industry.
“Since then,” Lew says about the project that ended in 2023, “we have been growing our presence in the countryside. Engineering is an important part of them because they are technical facilities and we need a partner ready to work with us in coordination. [Syska] It grows and looks to the future, we hope to do the same together with them as we look at other industries. We are excited about the future. “
The data center world is “very hot and active for us,” says Passanante, and the firm can have three offices across the country working in a data center as if they were a single office. “This allows us, if people in a certain sector are not busy, but they have experience, we can take advantage of these people to work.”
Develop diversification
Also in the West, Syska has been active at Los Angeles International Airport for the last twenty years, which has led to work at San Diego International Airport and the airport in Burbank, Long Beach and San Francisco. “We are working on almost every big one right now,” says Marcel. “We have great relationships and the right people ask us to be in the project.”
Syska Hennessy has remained relevant in criminal justice, civic work and health care (including life sciences) with a specific concentrated concentrate of the west coast in higher education, all from art theaters to student homes to dining rooms. Syska Hennessy has not moved away from its history of working with major financial intuitions on interior projects.
Being a private company, employees are very careful at work, says Marcel, noting that customers have said they know they can call and that Syska’s employees will pick up the first ring.
“We know this is a service industry,” says Marcel, “so we are putting people in the right position so that we can deliver.”
Advanta, Passanante knows that the acquisition of talents will remain a key challenge. The firm has not tried to grow too quickly or move towards acquisitions because it wants to keep current culture in its place. Instead, it focuses on developing talent and experience. Syska works with organizations to create an amplitude and a depth of expertise in the engineering sector. Syska has sought to develop growth in the existing offices and the offices where they already have experience.
“We want to be considered as the main engineer, that partner for clients who seek to do difficult projects or a large scale that really need technical experience,” says Marcel. “We feel where we belong.”
