A method of doing business is practiced by a group of independent professionals to meet the varied but related needs of an individual. The method uses a centralized computer system to coordinate professional services to an individual. Professional entities, such as attorneys, physicians, pharmacists, realtors, architects, financial institutions and advisors, insurance agents, bondsman, psychologists, enter into a coalition agreement. The coalition agreement defines a standard infrastructure comprising documentation, modes of communication, and administrative case management, all of which are operable and accessible through the centralized computer system. The professional entities form facilitator groups directed to particular multi-disciplinary problems, which individuals face. The standard infrastructure coordinates the activities of the professional entities. Individuals benefit by having a coordinated approach to their problems and convenience of an apparent single provider through a single user interface.
