Before launch: add real, permissioned client comments under Testimonials in the WordPress admin, then delete this note. Do not republish Google or Avvo reviews without the client’s consent, and never write one yourself, fabricated testimonials violate bar advertising rules in all six states and the FTC’s rule on fake reviews.
The most credible thing you can do here is link to your live Google Business Profile reviews rather than curating quotes. Add that link under Firm Details → Authority Profiles in the Customizer and it will also be published in your schema as a verification signal.
