Lawrence C. Mroczek (Larry) - Owner, Head Auctioneer 

Lawrence Mroczek is the founding partner of Mroczek Brothers Auctioneers & Associates also known as MBA Seattle Auction House. He grew up in the auction business started by his parents in 1966 and has been a licensed auctioneer since 1967. At the age of 26 Larry co-founded MBA Auctions in 1977 and has been running it ever since.

Lawrence always had a passion for fine objects and artworks beginning his focus on traditional northwest art. The link between Alaska and the Northwest first interested him collecting Indian artifacts and paintings by Sydney Laurence and Eustace Ziegler. He has since opened his palette to modernism and the entire northwest school focusing on "The Mystics" including Mark Tobey, Morris Graves, Kenneth Callahan, and Guy Anderson among others.

Michael Mroczek - Co-Auctioneer

Michael Lawrence Mroczek specializes in Northwest Modern Art, including paintings and sculptures from 1930 to present, as well as American studio ceramics and glass. 

Michael was born into the auction business, with his father, Lawrence Mroczek, leading the family-run company.  At the age of 8, Michael began helping his father at the company’s estate auctions.  Years of exposure to the auction business, antiques, art, and rarities not only confirmed Michael’s interest in becoming an auctioneer, but also prompted him to attend the University of Washington, where he received a Bachelor of Arts degree in Art History.  During his time at UW, Michael discovered his passion—as well as his aptitude—for modern art. 

In 2005, after graduating from college and becoming a licensed auctioneer, Michael was finally able to use both his extensive experience working with the family business and his breadth of knowledge from college as an auctioneer at MBA.  His experience and education has allowed him to recognize quality in all genres of antiques and collectibles.  Michael is truly passionate about his career, and feels so lucky to be able to work with so closely with his family.

Aside from the fun he has working alongside his father at MBA, Michael enjoys spending time with his wife, Danielle, his friends, and his modern art!
