Tiffany Carlson
Co-Founder
“When we decided to start a family, it was important to us that we balance our work and family life and with Rock Solid, we have the ability to do just that. We’ve hired like-minded women with expertise in bookkeeping and payroll to help them pursue their professional goals while prioritizing their family. This work-life balance is what we want for our clients, as well! Let us do the accounting so you can get back to work and spend more time with your family.”
Founders Story
The Rock Solid story begins in Cloquet, MN, where founders Pete and Tiffany Carlson were born and raised. High school sweethearts, both attended the University of Minnesota – Carlson School of Management, where they strengthened their passion for accounting, Gopher sports, and each other. Ski-U-Mah!
Pete is a Certified Public Accountant and member of the Minnesota Society of CPAs with more than a decade of industry experience. He began his career at Boulay CPA and worked as the CFO of both Lindstrom and Capstone Homes before pursuing his dream to launch Rock Solid Financials.
Tiffany is also a Certified Public Accountant (inactive) and launched her career at Grant Thornton. She also worked for many years as a Senior Tax Analyst at Valspar until becoming a stay-at-home mom to her three daughters, Sarah, Hannah, and Eliza. Working part-time for Rock Solid has allowed her to stay home with her kids while continuing to do the work she loves.
Pete and Tiff are both active people and love spending time at the lake. They enjoy playing sports, especially golf and basketball. To say they are competitive would be an understatement! Pete and Tiff are die-hard Gopher sports fans. Pete loves coaching his daughters in soccer and basketball while Tiff loves cheering them on. Above all, their faith, family, and friends are their greatest source of joy.
