She specializes in bookkeeping, financial reporting, and tax preparation designed to keep businesses organized, compliant, and informed.
Her passion for accounting began in her family’s bakery in San Luis Río Colorado, Mexico, where she witnessed how disorganized finances could hinder business growth. That early experience continues to shape her mission today: empowering business owners with the knowledge, organization, and confidence they need to succeed.
Maria earned a degree equivalent to a Bachelor’s in Business Administration with an emphasis in Accounting and received her professional title designation as Contador Público (Public Accountant) from the Universidad Autónoma de Baja California in Mexicali, Baja California, Mexico. Her background includes progressive roles — from Assistant Controller to Accounting Manager — across diverse service-based sectors in both Mexico and Arizona.
She is an IRS-authorized Electronic Return Originator (ERO), a PTIN holder, and a participant in the Annual Filing Season Program (AFSP). With over 15 years of experience in individual and self-employment tax preparation, Maria also provides expert support for 1040 filings, ensuring compliance and maximizing tax deductions.
