Nelson Puett, Jr. founded Nelson Puett & Associates in September, 1949. He moved his offices to 5425 Burnet Road in 1954, which at that time, was considered the outskirts of Austin. In 2008, the office of Nelson Puett and Associates moved to 1718 W. Anderson Lane, just down the road from the original office.

Nelson Puett Jr. was active in homebuilding in Corpus Christi, El Paso, Houston, and all throughout the Austin area.  Nelson Puett, Jr. platted and built thousands of homes in what are now considered to be Old Austin's most coveted zip codes.  Neighborhoods like Crestview, Allandale, Rosedale, Brentwood, Hyde Park, Oakmont Heights, and Wooten Park all bare the signature Nelson Puett brand.  

The Puett Family has always taken great pride in nurturing first time homeowners and made loans to families for many years to aid in that pursuit. The Nelson Puett Foundation has awarded scholarships to young people in pursuit of a college education for many years. Little League football and baseball teams have played under the sponsorship of Nelson Puett & Associates since the inception of those programs in Austin.
