Gaston & Sheehan Auctioneers


Gaston & Sheehan Auctioneers, Inc. was founded in April of 1988 through a merging of the partners' operating businesses and years of experience. The company objective was to be a leading multi-facet auction company capable of responding to the growing demand of auction services throughout the state of Texas. Since the inception of Gaston & Sheehan Auctioneers our goal has been to provide the buyers and sellers with an auction service second to none. Gaston & Sheehan Auctioneers is a family-owned business committed to providing our many customers with the experience, integrity, dedication and knowledge required to achieve a successful business relationship.

Gaston & Sheehan Auctioneers serves clients such as the U.S. Marshals Service, U.S. Customs Service, Internal Revenue Service, Travis County, Law Enforcement Agencies, Bankruptcy Trustees and numerous commercial lending institutions.

The firm sells all the jewelry, art, antiques, gold, silver and collectibles seized and forfeited nationally for the U.S. Marshals Service. They have conducted numerous high profile auctions including the relocation of property belonging to James "Whitey" Bulger; a fugitive on the FBI's most wanted list. This inventory was relocated from Santa Monica, California to Boston, Massachusetts, where Gaston & Sheehan sold it in June 2016 at the Boston Convention Center.


Other notable accomplishments include the complete liquidation of the personal property assets belonging to Bernard and Ruth Madoff; relocated, stored and disposed of personal property belonging to Rita Crundwell, a convicted embezzler; as well as receiving national media attention when they were contracted by the IRS to auction an inventory of jewelry seized from the notorious Jimmy Chagra family of El Paso, Texas.

Our firm conducts over 100 auctions per year, offering and selling thousands of assets while continually maximizing our client's return. Gaston & Sheehan holds memberships with both the Texas Auctioneers Association and The National Auctioneers Association. Our firm and its auctioneers are licensed in five different states and consistently conduct auction events that draw a national audience. The staff comprises over 150 years of auction experience in all phases of the auction, real estate and vehicle storage industry.

In 2000 Gaston & Sheehan opened a full-service realty office. Gaston & Sheehan Realty is known locally for quality service to both buyers and sellers. The realty office has worked for many asset managers and REO sellers in the central Texas foreclosure market. We have a full-service property management staff as well as an experienced maintenance staff for property upkeep and preparation.
