Chiara Mattieson

Attorney at Law

Chiara Mattieson founded Mattieson Law, PLC in 2020, guided by the principle that legal services should be provided in a manner that is necessarily helpful to clients, not just a necessary expense.

Mattieson Law puts Chiara’s experience and skill to work for clients in a lean, agile, dynamic, and flexible framework that enables her to bring quality legal services and representation to a wider, more diverse client base and often enables her and her clients to see, and say “yes” to, strategies and solutions that may not have been identified or considered before.

Chiara is service-focused, knowledgeable, and honest. She started Mattieson Law in the midst of a pandemic and understands delivery of services in a straightforward manner that respects Clients’ time and resources, using technology like virtual meetings and solutions like flexible scheduling, is the way forward.

She has also begun a blog to provide insight and information to her readers. She welcomes transparency and wants people to understand legal processes and concepts.

"I take pride in my work. I know how to navigate the areas of the law in which I practice and I know how to do it well."
