Steven Mastanduno, Mastanduno Law Group 3

With over a decade of legal experience, Steven Mastanduno focuses his legal practice on family law, estate planning, and probate law, including estate administration and protective proceedings like guardianships and conservatorships, while also consulting on business and contract issues. He understands that every family goes through change and has its own goals, and when the legal system is involved, these changes can be challenging. This is even more true when it to comes to non-traditional and blended families. Steven will strive to make these life changes as smooth as possible for you and your family, and to help plan for what the future may bring. His focus is on resolving disputes without the need to litigate, but he is a capable litigator and can skillfully represent you in court. Steven is a qualified mediator and is happy to assist with guiding you towards agreements that make litigation unnecessary.


Steven was born in Portland, Oregon, and has lived here for most of his life. He earned a bachelor’s degree in Philosophy and History from Skidmore College in New York, and from there spent several years working as an educator and as a chef. He went to law school at Willamette University College of Law in Salem, Oregon. In law school, Steven focused his studies on dispute resolution and received a certificate in dispute resolution with his degree. In law school, Steven and Nate met and became friends, ultimately deciding to go into business together starting in 2015. Since then, Steven has been the managing member of our firm and continues to ensure that we provide high-quality legal representation.

Today, Steven lives with his fiancée, Alex, and their dog, Cosmo. When he’s not working, Steven enjoys gardening and thrift shopping, and returning to his first passion, cooking.

No case is complete until a resolution addresses everyone’s interests in a sustainable way.
