My name is David Therrien-Power and I am happy to provide civil and criminal litigation services and representation to the Yakima Valley and surrounding communities.  As a member of Yakima Law, PLLC, I strive to work with our growing team to engage with our community and assist our clients with a variety of legal needs.  As a former prosecutor and defense attorney, I have appeared on hundreds of felony and misdemeanor criminal cases.  I know that you and your family face a litany of tough decisions as you face prosecution and I am here to provide advice, support, and zealous representation to ensure that your rights are protected as you navigate the dauting prosect of being accused of criminal conduct.  I have also expanded my practice to include assistance with civil litigation and have represented clients in anti-harassment and protection orders, real estate disputes, contract disputes, business disputes, probate, personal injury, adult guardianship and employment disputes.  I believe that a direct, fair, and firm approach to disputes and lawsuits can bring good results to clients.  I also am happy to provide assistance with contract review, estate planning, and business formation  for those clients that need help but are not currently invloved in litigation.  Careful planning can help protect you, your property, and your business should you face a lawsuit in the future.  Please contact me if I can help you in anyway.  I look forward to assisting you.
