Lauren Gwinn
Associate

After nearly a decade serving in higher education and nonprofit organizations, Lauren felt called into a new industry, a renewed sense of purpose, and a career dedicated to giving back in a different way.


Lauren is now at Thrivent because she believes that she can make a real impact in people's lives through their finances.

She is so proud to work with women, families, individuals, small businesses, and nonprofits to sow seeds for their financial futures.


Lauren's goal is to help offer clarity on where clients are today and confidence for where they'll be tomorrow. Whatever stage of life, she is here to nurture the roots you’re planting and help you plan for tomorrow and the years that come.
