Yerkes Associates, one of the nation’s oldest civil engineering and surveying firms, commemorated its 150th anniversary recently with a special event at its headquarters. Yerkes leaders joined local and state officials, community members and employees to mark the firm’s century-and-a-half legacy and its pivotal role in shaping the Philadelphia region.
“Today is a momentous occasion for Yerkes Associates,” said Nick Cirilli, president and CEO. “This milestone reflects our unwavering commitment to quality, service and community. As we look ahead to the next 150 years, we remain dedicated to continuing to lead the way in engineering, adapting to the ever-changing needs of our clients and community.”
Founded in 1874, Yerkes Associates has been instrumental in the tri-county region’s development. From its early days of land surveying, including Valley Forge National Historical Park, to becoming a comprehensive engineering powerhouse, Yerkes has provided essential planning and design expertise for both public and private entities.
“It’s an honor to celebrate this milestone with Yerkes, a true pillar of our community,” said Sen. Carolyn Comitta (D-Chester). “Their contributions to the region are significant, and I know I speak for many when I say we’re incredibly fortunate to have such a visionary company right here in our backyard.”
During the celebration, Yerkes Associates presented a donation to the Valley Forge Park Alliance for the renovations and expansion of the historic Maurice Stephens House, where General Washington trained the Continental Army.
“Yerkes Associates has been instrumental in shaping the landscape of our community and the surrounding region,” said East Goshen Board Chair Michele Truitt. “Their work over the past century and a half has had a lasting impact on our infrastructure and growth, and we’re so grateful for their expertise.”
A display of historical equipment and original hand-drafted plans offered a glimpse into Yerkes’ storied past. The event concluded with a new signage unveiling symbolizing a bright future, followed by a reception.
Yerkes Associates was founded in 1874 by Samuel and John Garrigues. The company has played a vital role in shaping the development of Philadelphia’s Main Line and surrounding southeastern Pennsylvania region.
For over a century, four generations of the Yerkes family guided the firm’s growth, expanding its services beyond surveying to encompass civil engineering, planning, landscape architecture and municipal services. Today, under the leadership of Nick Cirilli, PE, PLS, Yerkes Associates is a full-service surveying, civil engineering and municipal services firm. The company is proud of providing efficient, effective and high-quality professional services.
With a strong commitment to the communities it serves, Yerkes Associates continues to be a trusted partner for both public and private entities, shaping the region’s built environment for generations to come.
