Added from Google Maps: For 1,021 licensed firms that we matched with high confidence to their Google Maps listing (October 30, 2026; matched by the state-listed phone, or by name plus the same street or ZIP), cards show the phone, website and Google rating from that listing, plus an email where the firm publishes one on its own website. Each addition is labelled on the card with its source and date. Individual licensees and firms without a confident match show only the state data.
