"People come into our lives who leave a lifelong impression - I know it sounds a bit cliché, but that's exactly who Alma was.
Yesterday, I learned from Patrick Misiewicz that Alma Kadragic passed away last August. She was my first boss and a pioneer of public relations in Poland.
In 1996, I began studying a second degree at the Center for Journalism, where I majored in Public Relations and Print Journalism (I'll delve into what the press entails some other time). The Public Relations classes were taught by Piotr Czarnowski, founder of Poland's first PR agency, First PR. After one of the classes, he offered me an internship at his agency and spoke highly of Alcat Communications, Alma Kadragic's agency, with which he co-founded the Polish PR Association and co-authored 'Public Relations, or the Promotion of Reputation.' As it turned out, Piotr and I couldn't agree on a start date. I then called Alcat, where Marcin Gruszka answered and offered me an internship. The pay was modest (I earned more selling cacti on weekends), but it was a start in public relations. That's where I met Anna Borys, who remains a friend to this day. Alcat was a well-known brand, and Alma was a renowned figure in the PR world and beyond. She had been a journalist for ABC News TV and the head of its Polish and Central Eastern European operations since 1980, meeting numerous opposition figures and more. She was particularly fond of Lech and, surprisingly, Urban. Her company was among the first members of the American Chamber of Commerce's Polish branch.
Eventually, I became Alma's deputy at Alcat. It was there that I learned about the industry, met important people, and gained invaluable experience. It was an exhilarating time of intense work, good pay, and significant networking. After two years, Alma shut down Alcat in Poland and left to teach at the University of Abu Florida in Miami. We met a few more times in Poland and stayed in touch sporadically. Last year was tough for me, and after one email, I didn't hear from her again. And now, I never will.
I had great respect and affection for Alma. But truth be told, she could be quite difficult at times. She didn't hesitate to dismiss people overnight, and if she believed she was right, there was no room for debate. Eventually, we parted ways, and I signed a non-compete agreement which barred me from working in PR for two years, prompting me to switch to marketing.
Alma was multilingual and spoke Polish quite well, despite mangling it amusingly at times. She taught me that it's better to speak a language poorly than not at all. I'll always remember her saying 'non-steti kotlet' and 'see you later alligator' to the President of Poland.
Once, Alma took me to the United States for the World Young Business Achiever competition in Orlando. It was an unforgettable experience, where I met her mother and her dog, Jingles. That trip was incredibly significant for me.
I often wonder who I would be if I hadn't crossed paths with Alma, but I'm certain I would be a different person."
