Local Lawyers With A Community Focus

Steven Mastanduno

Steven Mastanduno focuses his practice in family law, estate planning, and protective proceedings. Through his experience in these areas, he has come to understand that every family has times when change must happen, and that change can be challenging. When the law is involved, these changes can be particularly challenging. Steven’s goal is to make these changes as smooth as possible, whether your welcoming a new member into your family through adoption, figuring out how to transition from a relationship, or considering your end of life plans. His focus is on resolving disputes without the need for litigation, through alternative dispute resolution such as negotiation and mediation; however, he is an experienced litigator and is able to represent you in court if that is required.  
Steven was born in Portland and has lived here for most of his life. He earned a bachelor’s degree from Skidmore College in New York and went to law school at Willamette University College of Law. At law school, Steven met Nate and they became friends, ultimately deciding to go into business together. Today, Steven lives with his long-term partner, Alexander, and is a passionate gardener, cook, and thrift shopper.
