Our Story
Nordfiscus was founded in 2025 through the strategic rebranding of two well-established Canadian firms: Tessier Tax Solutions, known for its deep expertise in U.S. and Canadian personal taxation, and the Canadian branch of Expat Global Tax, a recognized leader in international and expat tax services. By joining forces, we created a unified firm capable of delivering a broader and more robust suite of financial solutions to clients across Canada, the U.S., and beyond.
Our name — Nordfiscus — reflects both our Canadian roots and our commitment to fiscal excellence.
Our Team
At the heart of Nordfiscus is a diverse team of highly qualified professionals, including CPAs, Enrolled Agents, and seasoned tax advisors. Collectively, our team brings together over 100 years of combined experience in domestic and international taxation, corporate accounting, and financial planning.
Each member of our team is dedicated to upholding the highest standards of professionalism, continuing education, and ethical responsibility. We believe in a proactive, personalized approach — taking the time to understand your specific situation and providing solutions tailored to your needs.
