Our Principles



A plan, method, or series of maneuvers for obtaining a specific goal or result.  Our strategic thinking focuses on working with our client and his/her professionals to achieve a result in our client’s best interest. This does not mean that the results of our analysis can strategically change. It means that based upon our analysis we can assist our client and his/her attorney in determining how to strategically achieve a positive result for a client. For example, we can help attorneys and clients determine how to globally assess support, equitable distribution and fees. We often assist attorneys in determining what discovery is missing, its importance, and how to obtain it. When we cannot assist a client in settling his/her matter, we work with the client’s attorney to determine how to strategically present the case to the Court.
