Can remember her name but this had only been my 2nd time being put under for a procedure. So when I was very nervous about the words sub conscious sedation for an endoscopy I freaked out. I don't want to watch a scope go down my throat and I surely don't want to be awake. When I told her that she said it would cost me more for the next level of sedation. I lost it! I became very emotional at this point and started calling my insurance company to figure out how much more I would be charged for the next level of sedation. Insurance assured me it was all covered. I felt better after that point. The gal that did the scheduling was also awesome as far as assurance and calming. I returned to this facility for a yearly procedure after this procedure and had a much better experience.

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.

I have recommended him to several people. He will be my gastroenterologist as long as I live in the Kennewick area. Excellent, excellent doctor!

My mom was having terrible complications due to her Diverticulitis. We had fought with another dr…read moreand got no where, so we finally saw dr Syvilla at the walk in. She was helpful at first and got us an appointment and surgery with dr Tuszynski at the end of December. Come time for surgery and it went well but in recovery they were not listening to her about her pain levels and kept brushing her off. I had to keep getting involved because they refused to listen. They sent her home with LESS THEN HALF the meds for pain management at home and her pain was BARELY controlled in hospital care. Her dr and the nurse kept writing her off and they finally gave her another appointment just to tell her she can take her meds as necessary cause Syvilla can overwrite the insurance restrictions. It was a joke, mom was in severe pain for a whole week before they finally told her she could get more meds. Now, she's having issues post surgery, the incision is herniated and she's having bleeding problems too. However, she's just received a letter from Confluence saying that these two doctors are no longer with them and moving to Samaritan. These drs left my mom with no aftercare appointments and no warning to have a follow up appointment with a different Gastroenterologist doctor. So, typically with surgery you're covered for 90 days in case of complications or issues or whatever. But not this time because they screwed my mom over by leaving with no warning. Now she has to receive another referral from her primary provider and hope and pray she can last till that appointment. I'm SEVERELY disappointed with these drs and confluence in Moses because they just dumped my mom and said good luck. I recommend asking tons of questions about aftercare and what to expect before signing up for surgery with these two. They knew long before they scheduled my moms surgery they were in the process of switching hospitals, so there should've been fair warning and there wasn't.
