About Stefek’s Auctioneers & Appraisers

For over twenty years, Stefek’s has operated as a full-service estate liquidation management company, serving Michigan and the tri-state area. Originally Stefek’s operated as an estate sale company – Lori Stefek recognized that the quality of items she was selling at estate sales deserved a global market, and established Stefek’s Auctioneers & Appraisers.

Stefek’s not only assists our clients with all phases of liquidating an estate, but also provides unparalleled customer service to each client. As a full-service boutique auction house, our mission is to utilize Stefek’s expertise and international reach to provide our clients with exceptional service.

Catherine Milewski, Auction House Manager, is an Accredited Member of the International Society of Appraisers with a concentration in Fine Arts and holds a Bachelor of Arts degree in Art History from Wayne State University in Detroit, Michigan. Focusing primarily on fine art and furniture, Catherine’s passion and expertise also encompasses personal property evaluations and consignment management.

Catherine’s enthusiasm for fine art started with her love of drawing early in her childhood. While attending classes throughout high school and college, Catherine’s appreciation for all mediums grew. Intrigued by the vibrancy of early 20th century prints and design, Catherine was drawn to learning more about the history of the pieces, artists, and techniques implemented.

Her early interest in the history behind the work helped Catherine curate her knowledge, education, and expertise to become a leading resource for Stefek’s clientele. Catherine enjoys continuing her appreciation and understanding of the arts by regularly attending gallery openings, art exhibits, classes, and conferences.
