What this firm has earned Every one from a measured value, with the evidence behind it
LFL Certified 2026
Scored 76 out of 100 on measured evidence, above the 70 this tier requires, with every eligibility gate its state allows us to check cleared.
No public discipline
None of the 13 named attorneys carries a disciplinary status on the public register: no disbarment, suspension or disciplinary resignation. Those statuses persist, so the check reaches back years, but it would not show a censure or a suspension since lifted.
588 client reviews
Counted across 3 verified Google Business Profile listings, not collected by us and not solicited through us.
4.7 average over 588 reviews
A high rating is easy at low volume and hard to hold at this one. Pillar C scores it against the market rather than against five stars.
Service in Spanish
Published by the firm on its own pages, which is how this was measured rather than assumed from a name.
95 results published
Across 9 case types on the firm's own site. We read the page and counted what is on it; the amounts are the firm's and we have not confirmed them.
