Celebrating Over 60 Years of Quality.

Southern California's most reliable commercial flooring contractor. 

Building Construction



Our Company

Lawrence W. Rosine Co. was founded over 60 years ago, in 1957, by Lawrence Rosine. After serving in World War 2, he pursued a Civil Engineering degree and quickly began contracting for commercial flooring jobs. With a focus on public works and healthcare, Larry became known for his dedication to quality and thoroughness.

That legacy still lives on at LWR. We are known specifically for our willingness and ability to get the job done correctly the first time. We are proactive in preventing issues from coming up and aggressively make corrections where needed to keep a project on schedule. Most importantly, we have earned the trust of some of the biggest names in Southern California by standing by our work.

The construction industry is changing and we are changing with it. Reports are expected in hours and updates are communicated daily. We are investing heavily in technologies and procedures that will allow us to keep with the everchanging contracting landscape for another 60 years.
