Our History

Johnson Design Associates, Inc. is proud to be a family-owned and operated business with a rich history in South Jersey. The Johnson family has been serving the community for over 130 years, starting with Wilde Farm Supply in 1886. Over the years, the family business has evolved, and in 1984, Daniel James Johnson, a civil engineer, opened Johnson Engineering. After his sudden passing, his brother Eric took over the business and expanded the services to include land surveying and environmental engineering, renaming the company to Johnson Design Associates, Inc. Today, our team is dedicated to continuing the family legacy of providing quality and affordable engineering and land surveying services to the community.
