Stumbled across the auction house and set up my account. Super easy to bid, the invoice arrived the next day and I went to the business and picked up my trinket. Pleasant staff and easy to deal with.

This is the best place in town to go look for that old fancy dresser that we always wanted. It was worth waiting until one came for sale. We paid a lot less than we would ever in an antique store and got a high quality item and great deal.

As far as auctions go I believe this is the number one auction in all of Washington or Oregon. I've been a customer for years, for buying and selling. It's a family-owned business. The employees are very helpful. You can truly find some very wonderful treasures here. As for all auctions the items are used so you must preview. The Auctions are held on Thursdays with most starting at 6 p.m. since you should preview I would get there one to two hours earlier.

This auction house offers a great variety of quality items at auction every month. I personally won a cup & saucer from the Nanking Cargo at their last auction and was more than pleased with their exceptional customer service and quick response to all of my questions. Definitely recommend this business!

Horrible Experience! If you want to get ripped off, then work with MDA Auctions. I consigned several items with them. They "failed" to list one item on my consignment sheet that was worth well over $150.00. When I asked about the item, I was told "we are busy" and don't have the time to research. Then I was told it must have sold with another item.the bottom line is they ripped me off!

Check you consignment sheet carefully. Especially if the son writes it up. In addition to all this, they are arrogant, unfriendly and act as thought they don't want or need your business! Take my advice.go elsewhere!

We were very happy with the service, communication, professionalism, honesty, and outcome of working with them! I would recommend MBA to anyone who wants a great auction experience with proven results. We would use them again without reservation.

I consigned an original oil painting by Seattle artist Ed Newbold to be sold at auction on November 30, 2017 with Mroczek Brothers. Everything went very smoothly. I enjoyed working with Mike and would recommend this business to anyone.

This family run auction house has impressed me with its integrity as well as with the scope of the items it runs through its auctions. Friendly, courteous and pleasant dealing with even when an occasional problem might arise. I would not hesitate to consign objects to them for auction, nor would I hesitate to buy at their location in Renton. It is a long trip for me to drive there, but it is always worth the effort. If I could think of even one negative comment, I would not hesitate to list it. They may not walk on water, but they come pretty darn close.
