5 /5 Kevin Mitchell: I saw Dr. Plumer and he was an absolute pleasure. Maybe the best visit I’ve ever had with a doctor and especially a gastroenterologist. I felt listened to, understood, and taken care of. Dr. Plumer took his time and I didn’t feel rushed at all. He knew exactly what was going on and took such excellent care of me that I can’t recommend him enough. Best gastroenterologist in Orange County !!!!
