In 1954, as the result of Hurricane Hazel, a young German immigrant named Herman Kassinger got his start in the construction industry. More than 1200 homes later, H. Kassinger Construction Limited has become known as a leader in the home building industry both in Canada and the United States.

Over the years, projects such as Beau Valley, Park Valley, Sun Valley, Rose Garden in Oshawa, and Highland Gardens in Courtice became the benchmark for production and custom residences and commercial buildings in the area.The premier rental community of Rossland Park was conceived as an unparalled collection of rental accommodations in 1965 and was completed in 1975.

In 1978 Herman Kassinger developed and built several upscale communities in Palm Springs, California. Additionally, he was instrumental in revitalizing the Palm Springs downtown core. Over the years many celebrities visited his popular dining establishment and shopped at the designer stores in the Bank of Palm Springs Shopping Centre.

After his passing in 2004, Herman Kassinger left the care of Rossland Park to H. Kassinger Construction Limited, a hand-picked group of talented professionals who were given the mission to ensure that Rossland Park tenants would enjoy a first class address now and for many years to come.
