“A successful business must have accurate accounting.”

Mario joined RBC in 2023 and serves as a senior in the tax department. In his daily work, he specializes in the preparation of individual and business tax returns. Mario brings four years of experience to this role and has worked closely with clients in the construction and transportation industries.

A dedicated professional, Mario attributes his success to ambition and a determination to never settle. His favorite quote sums up his commitment to teamwork and excellence: “The strength of the team is each individual member. The strength of each member is the team.”

Mario currently lives in Laredo, Texas, and says his favorite things about San Antonio are the opportunities it provides and its Hispanic influence.  In his leisure time, Mario is a sports fan who enjoys playing golf, recreational basketball, and competitive CrossFit. He is a fan of the Green Bay Packers and loves to vacation anywhere with a beach.
