We scored 115 Green Valley psychologists on eight factors, weighted as shown. A practice is ranked when its specialty is confirmed and it has 3 or more Google reviews or a claimed profile. A practice with no Google reviews scores zero on rating, review volume and recency. Other unknown factors are left out, not counted as zero. Scores last refreshed November 9, 2026.
Paid placement never changes a rank or score. Sponsored businesses are paid, labelled, limited to 3 and shown above the ranking, outside it.
