We have built our reputation on helping our clients navigate the Washington State legal system to accomplish their legal goals and protect their families. Having represented multiple generations of families in the Kirkland area, we have seen innumerable clients through difficult or complex situations, such as:

  • Adopting a child
  • Planning for the future
  • Losing a loved one

Working to minimize the likelihood of conflicts in the future, we provide objective representation and advice. Easing the tension that can accompany legal problems, we help our clients arrive at solutions that are fair to everyone involved.

Experienced Lawyers

Attorneys David Berkey and Mary Kooistra have committed their careers to empowering their clients and their clients' families. We will explain your options and take the approach that makes the most sense in your situation.

If aggressive litigation will be most effective, we are prepared to take your case to the courtroom. However, if an alternative solution will resolve your situation, we will recommend mediation, arbitration or collaborative law. We truly take an individual approach in your case.
