Our Providers
Rob Allen, MD
Dr. Allen joins us from Kaiser Permanente West Los Angeles, where he developed a strong reputation for delivering high-quality, patient-centered surgical care. He brings extensive experience, advanced training, and is board-certified in general surgery, including a Foregut Surgery fellowship at Keck Medicine of USC, with additional specialization in robotic and bariatric surgery. Originally from the East Coast, Dr. Allen is excited to transition to a community-based setting where he offers comprehensive care across the full spectrum of general surgery. His practice will emphasize bariatric surgery and both upper and lower endoscopy, including EGD and colonoscopy, allowing for streamlined, continuity-driven care from diagnosis through treatment.
