Bilingual and born in Soviet Russia, I bring a globally informed and well-rounded background shaped by cross-cultural roots, and a career spanning law, healthcare, supply chain, and client-focused service.

Professionally, I have extensive experience in legal case management, personal injury, client advocacy, and cross-functional coordination. From managing high-volume case loads to navigating sensitive conversations and complex workflows, I excel most when working with people. Whether supporting clients through challenging situations or collaborating with internal teams, relationship-building, communication, and human understanding are where I shine.

My earlier roles in healthcare, emergency services, phlebotomy, sterile processing, and supply chain have shaped my ability to stay calm under pressure, communicate with clarity, and adapt quickly to diverse environments. This wide-ranging background allows me to bridge gaps, solve problems, and bring a grounded, people-centered approach to every role.

Outside of work, I’m happiest exploring the PNW with Luna–my black Lab and my heart- hiking, camping, cooking, and sharing good food with good people. I love plants, the outdoors, and continuous growth, personally and professionally.
