Meet the Founder of Halal CPA, PLLC

About John Morsequillo
Founder & Principal CPA
John Morsequillo is the founder of Halal CPA PLLC, where he combines Big Four expertise with cutting-edge tax technology to deliver comprehensive financial solutions. His mission is simple: provide small businesses and nonprofits with the same enterprise-level accounting, tax strategy, and technology implementation that Fortune 500 companies receive—without the enterprise price tag.
Born in the Philippines and raised with strong values of integrity and hard work, John moved to California to pursue his dream of becoming a CPA. He graduated from California State University, Sacramento with a Bachelor of Science in Accounting and Management Information Systems, launching a career that would span Big Four accounting firms and some of the world’s most recognized brands. After establishing himself in the industry, John relocated to Seattle, Washington, where he founded Halal CPA PLLC to serve clients nationwide.
What sets John apart is his unique combination of traditional accounting expertise and advanced technology proficiency. While most CPAs focus solely on tax compliance and bookkeeping, John brings specialized knowledge in enterprise resource planning (ERP) systems, tax automation platforms, and data analytics—expertise typically found only in large corporations and consulting firms.
John’s commitment to service extends beyond accounting. As a U.S. Army Reserve IT Specialist since 2020, he designs and maintains secure systems supporting mission-critical military operations. This dual role reinforces the precision, reliability, and disciplined approach he brings to every client engagement at Halal CPA PLLC.
