Largest and best-rated employee benefits brokers in San Antonio
Two rankings from public data: Google ratings for the offices employers review most, and the number of Texas employers that named each broker office on their 2024 Form 5500 benefit-plan filings. 42 San Antonio broker offices appear on those filings, named by 278 employer filings covering about 394,000 employees. This is a count of filings, not a quality rating; the brokers at the top serve the most employers, and the lists further down show who works most with small, mid-size and large groups.

Not necessarily. Employer counts show reach, not service quality. Large offices tend to work with larger groups; smaller agencies often give small and mid-size employers more direct attention. Compare a few brokers on market access, renewal strategy and who will handle your account day to day.
How to read this list
Where the numbers come from
Employers that offer group health, dental, vision, life or disability coverage file Form 5500 with the U.S. Department of Labor each year, and Schedule A of that filing names the broker paid on each insured plan. We count, for every San Antonio broker office, how many Texas employers named it on 2024 filings. How the directory is built.
What it leaves out
Employers with fewer than 100 participants generally do not have to file for an insured welfare plan, so brokers who work mostly with small businesses are under-counted. Self-funded plans with no insurance contract have no Schedule A, so brokers who specialise in self-funding are under-counted too. A broker named on a filing may share the account with another firm.
Does size mean better?
No. A large count means a broker has many clients and carrier relationships; it says nothing about service. For a 50-person company, a broker with 20 similar clients may be a better fit than one with 500 large ones. How to choose a benefits broker.
