Humble. Honest. Pragmatic. A small-town girl with a hard rock side.

Adept at simplifying daunting tax situations, Sonjia draws on her Big 4 accounting firm and Washington Department of Revenue experiences to deliver actionable solutions to clients. With her impressive dossier and huge heart for helping others, she’s a powerhouse on any tax team and the leader of our SALT practice.

A military kid, Sonjia grew up in Illinois and California but now calls the beautiful Kitsap Peninsula in Washington state her home. Poised between Seattle and the Olympic National Forest, the area is the perfect playground for Sonjia’s outdoorsy family. An avid camper, Sonjia is on a quest to visit all the country’s national parks, though none may top her favorite—the Great Sand Dunes.

When she’s not sleeping under the stars, you might find Sonjia enjoying a metal concert with thousands of her best friends. She’s been a huge Metallica fan since she was 12 and is surprised as anybody that she hasn’t outgrown her punk rock phase.
