When Ilmars Lagzdins first opened the doors to his Eureka office in 1954, serving the far reaches of Northern California was just a dream. A few years down the line, Lagzdins welcomed a new partner to the firm, Guy Conversano, and together, they incorporated the business in 1975, drawing upon their own last names for inspiration. Lagzdins contributed the “LA” and Conversano the “CO,” adding “Associates” to form a name that is now recognized throughout our communities.
Despite our growth at LACO, we have retained the responsiveness and personal touch of a small firm while demonstrating the management of comprehensive and sophisticated projects to meet our client’s needs. We rely on our experts, collaborators, and client vision to get the job done, while remaining steadfast to our mission to advance the quality of life for generations to come. In all we do, we model our core values: community, flexibility, and trust.
