About Us



MKJ Associates began in 1990 as a group of service professionals dedicated to producing catalogs for clients in the collectibles business. The tradition of service for catalog-based clients continues to this day. Our clients typically come to us with a variety of needs, ranging from minor assistance in finishing a large catalog project, to simply presenting us with "raw" (undescribed) merchandise, which we take all the way to a printed catalog.

In 1995 we began selling directly to our clients our catalog management and general office software (which had originated as in-house software to handle our own very demanding needs). We aim to provide the most advanced, sophisticated, state-of-the-art software possible to our clients, aiming above all else at improving our clients' speed of operations.
