Karlee Tiesler, EA, is the Accounting & Payroll Director at WCG, where she leads teams, solves complex operational challenges, and supports clients with practical financial guidance. Known for her steady leadership and problem-solving mindset, Karlee helps create clarity in areas that often feel overwhelming for business owners.
In her role at WCG, Karlee spends her time mentoring team members, addressing complex issues, communicating with the IRS and other agencies, and guiding clients through payroll and QuickBooks matters. She works closely with her teams to balance workloads while ensuring clients receive dependable, high-quality support.
Karlee enjoys the variety that comes with supporting small businesses across industries—from law firms and healthcare organizations to nonprofits. She finds each business model uniquely engaging and values the opportunity to help owners better understand and manage their financial operations.
Karlee earned her accounting degree from Mitchell Technical Institute, where courses such as Governmental Reporting and Business Law helped shape her technical foundation. An influential high school accounting teacher also played a meaningful role in inspiring her career path.
She is an Enrolled Agent and a QuickBooks Certified Advanced ProAdvisor in both Online and Desktop platforms. Karlee continues to expand her expertise through ongoing education focused on S corporations, QuickBooks, and payroll practices to remain current in a constantly evolving field.
Karlee’s goal is to make financial processes straightforward and approachable. Whether guiding clients through QuickBooks or helping them respond to payroll notices, she focuses on teaching, clarifying details, and providing reassurance so clients feel supported and confident in their decisions.
Born in Maryland and raised in Minnesota, Karlee grew up enjoying lake-filled summers, camping trips, volleyball, and long hours spent reading outdoors. Her early love of activity and curiosity helped shape the balanced, engaged perspective she brings to both work and life.
Outside the office, she enjoys bowhunting, golfing, camping, playing volleyball, and traveling to Montana. Community involvement is also important to her—she serves on her local school board and has volunteered with Junior Achievement for many years, teaching students about careers and entrepreneurship.
Karlee is known for her ability to quote movies—especially Harry Potter—with impressive accuracy. It’s a lighthearted reflection of the same attention to detail and memory that support her effectiveness as both a leader and advisor.
