Our Founders
Circa 1976
Phil Linscott, Bill Law, and Jack Greenspan


Linscott Associates was founded by Phil Linscott in 1966, with the help of his wife Betsey, to focus on traffic and parking issues. We were one of the first independent firms in Southern California (that is, not a local office of a national firm) and remain independent to this day. Jack Greenspan joined the firm later that year, and Bill Law did so in the early 1970s. By then, we were three (namesakes, that is) and the company name was broadened to Linscott, Law & Greenspan, Engineers, a California Corporation, in 1976. Or for short, simply…LLG.

In 1984, Phil retired, and we continued as Linscott, Law & Greenspan, Engineers, but changed our incorporated name to LG2WB Engineers, Inc. to reflect the initials of the remaining and emerging company leadership at the time. This was significant in that the company leaders were grown largely from within, a practice that continues to this day. Bill subsequently retired in the early 1990s as did Jack in 2005. As they did, others emerged to lead the firm, our staff grew to more than fifty, and our offices continued to expand in Pasadena, Irvine and San Diego, while working on a variety of challenging assignments from an enviable client list.

Having achieved our 50th birthday on November 1, 2016, and while looking forward and beyond, we remain an independent firm, led by a Management Committee committed to the core values and integrity of our founders. The men and women of LLG have worked diligently to establish and maintain a reputation for providing quality services that are insightful, accurate, timely and in the traveling public’s best interest. In consultation with the public agencies, owners, developers and other design professionals, we remain committed to the fundamental values of our history while providing exemplary service to our clients.

Our Legacy

On November 13th, 2016 the LLG family proudly celebrated our 50th anniversary.  The event was held aboard the Hornblower Endless Dreams in Newport Harbor, and featured three of our founders; Betsey Linscott (wife of Phil Linscott), Bill Law and Jack Greenspan.  It is rare for a company to maintain its original private ownership for five decades, and rarer still for the founders to be able to see how their legacy had developed.  This was the first time that Betsey, Bill and Jack have all been together as a group in nearly 30 years, and it afforded our current leadership and staff the pleasure and honor of meeting them to celebrate this incredible milestone as a group.  The cruise provided a picturesque venue for socializing, dining, and viewing an extensive slide show featuring photos of company events and staff members old and new. There were plenty of warm memories and laughs to be had of yesteryear fashions (thank you, 1970’s), and we were blessed with perfect weather for a perfect party.  Enjoy the celebration photos!
