Top 8 Best-Rated Gastroenterology Doctors in California (2026)

Each doctor's leaderboard score combines (a) average patient rating on a 5-point scale and (b) the natural log of review volume. A doctor with many reviews at a slightly lower rating ranks higher than one with very few reviews at a perfect rating - because volume reflects sustained patient satisfaction over many cases.

Only doctors with a verified Gastroenterology specialty in California on the federal NPI Registry are eligible. Only reviews submitted through the form on the doctor's profile and approved by our human moderation team count toward the score.
