BROCK & CO. provides assistance in evaluating and purchasing art sold through auction houses all over the world. We provide reports on the historical significance of the artwork, thoroughly examine the condition, review the current art market, and help determine the bidding strategy. We bid for clients whose schedule or geography limit their ability to do so, or for those who wish to remain anonymous to the public and press.

Working with accountants and lawyers, we offer consultations to discuss options, such as selling art or making planned gifts.

Mark Brock is best known for his keen ability to treasure hunt. He has a wonderful variety of resources and an amazing amount of energy. He enjoys helping clients reach their goals.

We are always interested in outright purchasing of artwork, as well as working on a consignment basis. Drawing upon our client base, we discretely offer your artwork on a commission basis.

BROCK & CO. provides advice in developing new art collections. This includes educating clients by accompanying them on visits to local museums, as well as suggesting general art reference books and catalogues specific to their interests. We develop a plan for clients to determine their collecting goals and their budget. We enjoy encouraging new collectors, and find that many return later for help upgrading their collections.
