Billing is a nightmare: sent a bill after 9 months stating owed more money and gave three weeks to pay. The insurance would not pay becuz the provider billed incorrectly!

OK--if I had to review this office separately from the Dr, my rating would be a bit different…read more First of all, Dr. Mueller came highly recommended from 2 other doctors of mine and I thought he was an excellent doctor; both his bedside manor and his knowledge. I had my colonoscopy at the KGH medical mall and the staff there was wonderful, I wish they were the ones who worked in his office. Dr. Mueller's rating would be 5 STARS! His office staff on the other hand is another story. Complaints: being rescheduled for EVERY appointment I have ever had in the office, receptionist answering her cell phone (person call) while she was trying to schedule me for my next appointment, being rushed when they scheduled me at the wrong time, wait time longer then usual due to them calling back patient in the wrong order, women nurse RUDE and I question their HIPPA certification. I heard them talk about patients first name, last name, DOB's and medical issue out in the front waiting area for everyone to hear. I know there are times when that will happen, but I felt like I knew more about their patients then they did. I questioned myself if I wanted to continue with this doctor, but proceeded anyway. The only person who I have dealt with who was polite and professional was the male nurse. He knew how upset I was at my last office appointment and I could tell when he was apologizing for the office that I wasn't the first person he had to apologize to. Office staff rating would be zero stars.

He said it does nothing for some people and like a miracle to others. It was a miracle solution for me. He has also told me other natural remedies, that have worked on issues as well. I love his wonderful bedside manner. He is sweet, extremely knowledgeable and very kind. He does not hurry you, and takes whatever time you need to discuss your problems. I have recommended him to several people. He will be my gastroenterologist as long as I live in the Kennewick area. Excellent, excellent doctor!
