However, she is also trained in collaborative law, and works with other trained collaborative attorneys in resolving cases outside of the litigation process. In addition, she prepares simple estate documents for her clients, including wills, Powers of Attorney and living wills.  In her spare time, she bowls, visits her grandchildren and runs.
