The story of Katzen Real Estate begins in the mid 20th century with visionary entrepreneur, Harry Katzen. In the rural town of Sykesville, Pennsylvania, Harry ignited his pioneering ventures, providing essential dead stock handling services to local farmers, collecting furs from hunters, and was an essential part of the war effort in World War II by providing raw materials to manufacture glycerin for military explosives. These services not only established a foundation of trust with the community but also gave Harry deep knowledge of the local real estate market. He seized the opportunity to invest his business profits into acquiring land and farms, eventually owning thousands of acres and dozens of farms.

After Harry's untimely passing, his son, Marc Katzen, took over the business at 16 years old. Marc exhibited extraordinary resilience and business acumen, managing the family enterprise while serving as a Jefferson County Commissioner and practicing law. Under Marc’s leadership and dedication to public service, the business expanded into office and warehouse development in DuBois, Pennsylvania. Marc’s entrepreneurial spirit and public service commitment laid a strong foundation for the next chapter of Katzen Real Estate. 

The third generation continued to build on Marc’s success. Marc’s sons, Hank and Hirsh, joined the family business and played a pivotal role in expanding beyond Pennsylvania.  Hank re-purposed the name "MarKay Farms" into "MarKay Management," symbolizing both continuity and a focus on growth. After developing office buildings and Taco Bell franchises in Pennsylvania, Hank relocated to Florida with his family and worked alongside his father to make strategic investments, including the acquisition of developable land, historic office buildings, and a shopping center across from the University of Central Florida. Hank and Hirsh were instrumental in managing these properties and overseeing their eventual sale, leaving a mark of strategic growth and community involvement.

Hank’s passion extended far beyond business. A proud advocate for the Jewish community, Hank was a cornerstone in the transformation of Central Florida Hillel and the construction of The Towers at Knights Plaza, a luxury dormitory project that created a sustainable financial model for Hillel while enhancing student life. Hank Katzen was a dynamic entrepreneur, philanthropist, and community leader whose life was defined by his dedication to innovation, family, and giving back. Hank’s people skills and relentless drive to "chase the deal" were legendary, making him a standout figure in the world of real estate and development.  Known for his humility, generosity, and sense of humor, Hank’s infectious enthusiasm inspired those around him to dream bigger and strive for more.

In more recent years, Hirsh and Hank worked together to acquire warehouse and office properties in central Florida, demonstrating the Katzen family’s continued focus on strategic investments and portfolio diversification.

Following Hank’s passing, his youngest son Mason joined Hirsh, continuing the four-generation family legacy.
