POLSERO – a leading Polish producer of high-quality milk powder, caseinates based on acid casein, and functional dairy-whey blends for the food industry.
Since 1993, our production facility in Sokołów Podlaski has been supplying top-quality raw materials daily to partners both in Poland and abroad.
Our business principles are reliability and transparency. Thanks to these values, we have maintained long-term partnerships—some lasting over 30 years—with clients in the ice cream, confectionery, bakery, dairy, and sports nutrition sectors, building strong and lasting business relationships.
The company owes its success to its founder, Zbigniew Seroczyński, who, with great talent and knowledge, passion, dedication, organizational skills, and a big heart, built Polsero from the ground up. Mr. Zbigniew is a true legend within the family, the company, and the local community. In addition to his business acumen, he was known for his generosity, kindness, and goodwill, as well as his strength of character.
Today, this family business is continued, shaped, and developed by his children, employees, and partners, led by Tomasz Seroczyński, the current CEO.
