About Our Consulting Group

Diehl Consulting Group (DCG) utilizes a multi-disciplinary approach to service delivery. While each project is led by one of our professional consultants, we emphasize the importance of collaboration both within our own organization and with client organizations. We have also formed regional and national partnerships with a number of contracted field consultants with varying expertise (e.g., psychometrics, advanced data analysis, and software development). This approach capitalizes on various expertise and allows for tailoring overall service delivery to specific client needs.
