—Heather Thiessen, Business Development Advisor

Professional Background

Heather spent the first 16 years of her career in hospitality, where she developed a strong foundation in relationship building, anticipating needs, and creating thoughtful experiences. Her own journey toward greater financial literacy inspired her transition into financial services in 2017 and a desire to help others feel more confident navigating their financial lives.

Heather began her financial services career as an Associate Financial Planner with Mainspring Wealth Advisors, where she supported both financial planning and practice growth. She later spent five years with Brighton Jones, working closely with prospective clients to understand their goals and connect them with appropriate financial planning resources. Over time, Heather discovered that business development, or what she considers relationship development, was where her strengths in connection, communication, and financial planning came together most naturally.

Personal Pursuits

Heather lives in Seattle with her husband and son. A lifelong lover of the culinary arts, she enjoys exploring new restaurants, developing recipes, and bringing friends and family together around the table. She also loves traveling, dance, music, and continually finding new opportunities to learn and grow.

Community Impact

Financial literacy is especially meaningful to Heather. She helped develop curriculum for an eighth-grade financial literacy course through CHOICES, a nonprofit focused on helping young people better understand the connection between education and future opportunities.

Heather also serves as Research Lead for the Maternal Pituitary Support Group, a UK-based nonprofit, and volunteers with Solid Ground’s Community Food Education program, helping make practical resources and education more accessible within the Seattle community.
