Practice Areas


Just as money can become a source of stress during a marriage, it also is a main point of contention during a divorce or separation.


We work collaboratively with the other side to achieve a fair and peaceful resolution. 



Divorce is a life-changing experience and an emotional roller coaster. We’re here to make things easier.


We can help you map out a plan of action and begin acting on that plan right away. No one should ever have to live with abuse.


Mediation has many benefits, including lower costs, less emotional conflict, a much shorter wait for resolution and the ability to have control over the outcome.
