About Us

Business growth is just around the corner.

At Costelloe & Associates, Inc. we have worked in many industries including Healthcare, Financial Services, and Retail specific clients. Through our diverse and experienced associates, we assist organizations in each of these areas. We would like to meet and discuss the benefits of our services and specifically, DISC in helping your organization become more effective and productive. We have found that companies who begin by offering DISC to all or a select group of associates have built more effective and productive teams as well as reduced turnover. In today’s environment, Psychological Safety is paramount to creating an environment for safe interpersonal risk taking and the DISC is an outstanding option to begin this process between any level of associate and their supervisor.  

Call us today and let us help you grow your business.
