A Long Beach Story, Forty Years in the Making

In the neighborhoods of Long Beach, where families stay for generations and community ties run deep, Aragon, Santillan & Associates has been part of the local landscape for nearly 40 years. What began as a small tax office founded by Ophelia Aragon—at a time when women rarely owned firms in this industry—has grown into a trusted, multi-generational practice serving families across Long Beach, Lakewood, Signal Hill, and the surrounding communities.

Built on Relationships, Rooted in Long Beach

Ophelia built her business from the ground up, gaining the confidence of local families who valued her warmth, precision, and strength. Many of those early clients stayed for decades. Their children grew up visiting the office with their parents, and now they walk through our doors with kids of their own. The heart of the practice is still the same: treat every client as if they are part of the family.

Today, the firm is led by Ophelia and her son, Fabian Santillan, working side by side. Together, they bring a rare blend of legacy and modern expertise. Both have earned the prestigious Enrolled Agent (EA) designation and are proud NTPI Fellows, giving them full federal authorization to represent clients before the IRS in audits, collections, and appeals. It’s tax knowledge at the highest level—paired with the familiarity and trust only a family-run practice can offer.

A Family Practice With Deep Expertise

What sets Aragon, Santillan & Associates apart isn’t just our credentials—it’s our approach. We don’t rush. We don’t treat people like numbers. We take the time to explain the why behind every recommendation so clients understand not just their taxes, but their financial picture as a whole.
