Fritz Dietl

Founder, President

Fritz Dietl, President and Founder of Delaware Freeport LLC (DFP). started a lengthy career in art storage and logistics as an apprentice in Vienna at Kunsttrans, the premier art-handling service provider for museums, galleries and collectors in Austria. He mastered all aspects of the trade during his tenure there, from truck driving, to wrapping and packing invaluable and unique works of art, and coordinating global art logistics services while negotiating complex customs and tax procedures.

After moving to New York in 1988, he started Dietl International Services, which he leads to this day. What began as a small, two-person office at JFK airport in New York has become the largest logistics provider in the United States devoted entirely and purely to the special needs and requirements of shipping artwork. With eight locations throughout the United States, Dietl International now has more than 70 employees dedicated to the safe transportation and handling of valuable works of art. Mr. Dietl is a founder and board member of a leading art handling, crating, and storage provider in New York state that manages over 150,000 sqft of art space. Seeing a need for specialized services in Brazil, he founded WaiverArts, now the leading art services provider in Brazil, and maintains a presence on the board. With more than 30 years of industry experience, he is a highly respected member of the international art shipping community.

He continues to enjoy getting involved in the day-to-day logistics and coordination of art shipments, on the ground; you may certainly find him pushing a crate or two, or installing complicated artworks, at many of the major international art fairs.

Andy Aigner

Operations Manager

Andy Aigner spent a number of years of owning and operating various restaurants and life entertainment venues catering to the young and burgeoning art scene in Austria and Berlin before moving to New York in 1987 to pursue his interest in fine arts. He managed an Art Deco design store on Madison Avenue and quickly found an interest in the restoration of fine art and antique furniture. He left the design store to open a high-end interior design and contracting business, which ultimately led him to founding and managing a New York City-based art storage and handling company. After a brief European sabbatical with his young family, Andy returned to the United States as crew chief of Dietl International Service's art fair installation team.

Mr. Aigner recently planted roots in Delaware to run the daily operations of the Delaware Freeport, and shares his extensive experience in art handling, installation, and restoration with the entire team as well as the facility's clients. Andy's interest in alternative energy has been the guiding force of the build-out of the warehouse, striving to make the DFP a green energy efficient facility. 

When Andy isn't working, he indulges his passion for organic farming.


Jennifer Schansberg


Jennifer Schansberg is one of those rare individuals who decided in the 2nd grade what she wanted to be when she grew up, and has been involved in doing just that, in some fashion, for her entire adult life.

Ms. Schansberg began by designing her own internship for an inventory project for her university museum in 1991, before moving on to many various registration jobs: documenting and inventorying new and existing collections for the United States Holocaust Memorial Museum, working in various capacities of the National Park Service's NAGPRA office for many years, and finally becoming a freelance registrar in 1999. As a contract professional, she managed numerous large-scale exhibition and permanent collection projects, both internationally and domestically. In 2012, Jennifer was hired by Dietl International Service to open the Washington, DC regional office and manages museum, gallery, and private collection art logistics projects throughout the Mid-Atlantic and the entire United States. In 2015, she was additionally tapped for the role of Managing Registrar for the DFP, utilizing her registration experience to provide the checks and balances needed to ensure the highest standards in handling and inventory controls.

Jennifer brings her enthusiasm to all aspects of her multi-faceted jobs. However, when she isn't working, her preference is to be in a place underwater in some exotic location, looking for sea turtles, spotted eagle rays, and Christmas tree worms.
