About the firm
A federal credential,
a local team.
Fast-Track Filing is the Coral Gables tax and accounting practice of LGA Services LLC — an Enrolled Agent–led firm built for business owners, families, and foreign owners of U.S. companies.
Principal
Luis Gonzalez, EA, CAA
Luis is an Enrolled Agent — enrolled to practice before the Internal Revenue Service since 2017 — and an IRS Certifying Acceptance Agent (since 2021) for ITIN applications. Every return is prepared in-house under his supervision; he reviews and signs each one and handles all IRS representation.
His tax career began in 2011 — preparing returns in the IRS VITA program and teaching the H&R Block Income Tax Course — before founding this practice in 2015. He holds a Master of Science in Accounting from Grand Canyon University and a BBA in Finance from Florida International University.

The people behind your file
Five specialists, one engagement flow — strategy, operations, tax build, books, and delivery — with every return filed under the EA's review and signature.

Cathy Gonzalez, ALM
Firm strategy and operations. Master's in Management (ALM), Harvard University — Harold Langlois Scholar, Class of 2022.

Suheily “Sully” Sánchez Ríos
The firm's operational lead — manages every engagement end to end: full-cycle payroll, company formation, and individual and business tax workflows from intake through EA-reviewed filing.

Barbara Beatriz Caceres Olave
Tax compliance specialist — builds individual (1040) and S-corp (1120-S) returns in Drake from source documents to review-ready workpapers, under the EA's review and signature.

Natalia “Naty” Santander Naranjo
Full-cycle bookkeeping in QuickBooks Online and Desktop — monthly reconciliations, clean ledgers, and year-end close packages that flow straight into the tax file.

Dilenny De La Cruz
Tax engagement delivery — runs filing-season closeout: return delivery, e-signature coordination, and payment, so every filed return lands complete. Questions about the return itself go to the EA.
Separate company
Fast-Track Insurance LLC
Health coverage is handled by Fast-Track Insurance LLC — a legally separate company with its own client files. Tax documents stay with the tax practice; insurance documents stay with the insurance agency.
