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.

Jess was born with two major goals for her young adulthood; become a registered nurse, and play collegiate ice hockey. At a small rural college in New York, she was able to accomplish both. She began her nursing career as a hematology oncology nurse where she was able to work with a niche and vulnerable population. While working day in and day out with extremely sick cancer patients, Jess felt both rewarded and saddened. Jess had a fire in her to do more than just treat, but also help prevent life altering diseases.

When Jess and her husband had the opportunity to move to the PNW, this was the perfect time to combine her love for wellness with her love for nursing. Origin Medicine is the perfect place to begin this calling of helping people before it is too late.

Jess lives in Tacoma with her husband, Stetson, their son, Maverick, and their two beloved hound dogs, Reba and Moco. In her free time, the fam enjoys any activity outdoors; skiing, hiking, paddle boarding, and anything else you suggest for her to try.  Jess is thrilled to partner with Michelle in help you reach your goals.
