Erin Rowan is not your typical CPA.
Raised in a family with deep roots in Mandeville, Erin remembers when Hwy 190 was still lined with trees.
“I just love this city,” she says. “I loved Mandeville before it was cool to love it.”
She grew up watching her father, an architect, shape many of the structures that define the community, including Lake Harbor Middle School, the Mandeville branch of the post office, and the St. Tammany Parish Hospital. By twelve, Erin was already volunteering at the hospital’s gift shop, which her mother managed.
That alchemy of ambition and expertise, grounded in discipline, curiosity, and long-range thinking, now defines Erin’s approach to accounting. After nearly a decade working across public accounting firms, she founded her own practice in Covington.
“At its core,” she explains, “accounting is a relationship business. You deserve a CPA who understands the story behind the numbers. Someone who believes in the future you’re working hard to build.”
Today, her work spans tax preparation and planning, small business accounting, and financial reporting. Her acceptance into leadership programs at the national and local levels reflects not only technical mastery, but also a clear ability to anticipate change.
What truly sets Erin apart?
Some point to her genius-level affinity for numbers, or her prescience. Others cite the calm confidence with which she guides clients.
But outside the office, her uniqueness shines brightest through her love of poetry (Sylvia Plath and Edna St. Vincent Millay), her dedication to distance running, and her affection for all things canine. With her husband, Chris, and their daughter, Marais Eve, Erin shares her home with three rescued German shepherd mixes (Pink, Floof, and Mama).
In a profession defined by rigid lines and hard edges, Erin transcends the stereotype, fusing head and heart, analysis and emotion.
If you’re seeking a CPA to help you or your business navigate the financial landscape of 2026, you’ll discover that Erin Rowan offers more than expertise.
She offers direction.
“It’s more than accounting,” she says. “It’s really about community. It’s about helping people build something that lasts.”
