About Us


It is our mission at Pel-Freez to manufacture and market quality biological products that meet or exceed the requirements and expectations of our customers as well as continually strive to improve the effectiveness of our quality system.


The company’s origins date back to 1911, when a pregnant pet rabbit was given to the son of Herman Pelphrey, a resident of Englewood, California. The newborn rabbit litter quickly grew and bred, eventually overrunning the Pelphrey home with rabbits. Turning the dilemma into an opportunity, Herman began selling fresh rabbit meat to his neighbors.

By 1918 Herman had begun marketing rabbit meat to the public under the name of the “H.F. Pelphrey Company.” In 1947, the company changed its name to “Pel-Freez” to capture the then-growing trend of frozen foods in the United States.  Around this time, Robert Dubbell married into the Pelphrey family, subsequently established Pel-Freez operations in Rogers, Arkansas, and began to enter into other markets for rabbit byproducts. As the pace of biomedical research increased throughout the late 1950s, the Biological Division was established to meet the increased demand for raw biologicals and intermediates.

Pel-Freez is currently the largest rabbit meat processor in the United States and is also well known for producing high quality raw and intermediate materials. These biologicals from a broad range of animal species are used globally in the development of in-vitro diagnostic kits, drug discovery, vaccine evaluation, HLA typing, and more in the biotechnology research and diagnostic markets. Pel-Freez Biologicals continues to produce high quality products, while providing excellent customer service.

Robert Dubbell’s son David acquired the company with his brother Paul in the 1970s and was instrumental in the continued expansion of both the Foods and Biological divisions.

On March 31, 2020, Pel-Freez was acquired by a private investment partnership led by Dr. Brian Bonk who relocated to Arkansas from Boston to replace David Dubbell as Pel-Freez President and CEO.
