Diane’s Beliefs, Goals and Principles

After working in the legal profession for the majority of my adult life, I have made it a priority to determine what my client’s goals are regardless of the matter before me.  Keeping my client’s goals in perspective, managing expectations and working toward my client’s goals are my top priority.  It is imperative that I keep close contact with my clients so that I am clear about the facts, that I ask the right questions and obtain information that can assist us going forward.

I have been not only an advocate but a party to family law litigation.  I strive to keep my client informed in the process by understanding their fear, loneliness and the stress of the situation.  My ultimate goal is to make the process smooth and understandable so that each client understands that, while they may not receive the results they would like, they understand why it happened.

I am unwilling to tell my clients my “success rate.”  As a family lawyer, it is not my goal to “win” but to achieve the best result possible for each client. The labyrinth of the family law process can be involved and complicated and I want my clients to understand it to the best of their abilities. My goal is to give them a sufficient understanding so that we can work toward an amicable resolution rather than going to trial or court which will work toward destroying the family to the extent it still remains. As much as I may enjoy the process of trial, the emotional and financial burden is extremely difficult for the family and can destroy the shreds of decency between the parties ultimately affecting the children’s relationships with their parents.

I have a reputation within the family law community of being nice but strong and tough.  I enjoy this reputation because it helps to obtain the best results for my clients.  I believe in being prepared for every foreseeable glitch, opening and opportunity to improve my client’s position which means my staff and I work around the clock to gather the most valuable information, research and evidence possible to achieve the best result.  I operate under the principles of integrity, professionalism and kindness; however, am always willing to try the case to a judge or jury to seek justice for my client and my client’s family.
