Meet Atty. Alexander L. Ullenberg:

Alex Ullenberg is the founding attorney of Ullenberg Law Offices SC. He represents clients throughout Wisconsin in asserting and defending their rights in and out of court.

Twenty years ago Atty. Ullenberg started Ullenberg Law Offices SC in Fond du Lac, Wisconsin from scratch — the day after he was sworn in to the bar. Today, his firm remains there and has a staff of four.

“The American legal system is one of the greatest parts of America’s democratic system.  I am proud to be part of a system that gives every person the right to challenge the wrongful acts of the most powerful, and force them to follow the rules.  I’m equally proud to help my clients structure their dealings to take maximum advantage of their rights under the law.  I’m not afraid to speak my mind, argue and pick a fight when needed or resolve that dispute in front of 12 fellow jurors.” — Alex


In 1994, Atty. Ullenberg graduated from Marian College with a Bachelor degree in accounting, completing the four-year program in three years. During that time he studied in England and traveled extensively abroad in Europe and Russia.

Hobbies and Interests:

“I like to golf (doesn’t every lawyer!). I travel and, although you wouldn’t guess from my picture, previously ran the Walt Disney World Goofy Challenge – running a half marathon (13.1 miles) on Saturday, then the full marathon (26.2 miles) the next day – a near-death experience. I enjoy trying new technology, and often have the latest gadgets on my desk.” — Alex
