Attorney Profiles

Dedicated and Experienced Kirkland, WA Lawyers

Berkey & Kooistra has been serving families and individuals in Kirkland for over 30 years. Founded in 1977, our mission has always been to advise and assist our clients in making informed legal decisions and to be an advocate for their interests in court. We provide affordable estate planning, assistance in estate administration (probate and non-probate matters), facilitate adoptions, guardianships and Medicaid planning, and represent clients in family law disputes. Our goal always is to educate, enable, and empower our clients. We are a people-oriented firm.

Where there is conflict, our goal is to be part of the solution. Both of us work collaboratively. Mary E. Kooistra is a trained collaborative attorney and member of King County Collaborative Law as well as the International Academy of Collaborative Professionals. David A. Berkey has mediated a number of family law disputes. We work toward resolution of conflict by fully informing you of your rights and your options, by treating all sides with courtesy and respect, and by efficiently and effectively representing your interests. We are prepared to be your advocate in court, but as a result of many years of experience, we believe that in most cases people are best served if a fair resolution can be reached outside of the courthouse. We want you, as our client, to have as much control as possible in the outcome of your case.   

Call 425-822-6311 or contact us online to schedule a free half hour consultation to discuss your family law, estate planning or probate concerns.
