"I had a major conundrum over Easter weekend that I desperately wanted rectified. My previous insurer failed to notify me that my auto insurance wasn’t current and told me that I needed a new quote (after being with them for 13 years). They were going to charge me $360/month for car insurance on two vehicles (over $200/month increase). Needless to say, I called most insurance companies in town to get another quote. Tanya from Greg Duncan’s office called me first (just after 9am on Monday morning). Tanya was empathetic, professional, and eager to help. She knocked off over $200 a month on my insurance and it was an absolute pleasure working with her. She made the entire thing completely painless. Honestly, she’s a life saver. I whole-heartedly recommend her and her company for insurance. I cannot see how you could be disappointed. 10/5"

"Greg Duncan State Farm in Council Bluffs is very accommodating. I was able to get my insurance the day I moved to IOWA. They also helped me when I moved across to Omaha, the entire staff has been great to work with. I only left their service because I moved out of the AOR. Unfortunately I moved to New Mexico and State Farm was kinda high and I had to switch companies. Anyway, thanks Greg and your staff for helping me right up to the last day!"

"Greg and his team have been responsive and caring when my family needs help. We’ve had a few claims and Greg personally has gone out of his way to assist, and then follow up with me after the claim has been processed and even after the work was done! I’d give more stars if I could."

They have been unbelievably attentive and helpful in resolving the claim and I am so appreciative of their attention to detail and willingness to go above and beyond to help and make sure everything was handled correctly. A huge thank you to the amazing staff!!"

"I have been with Greg for over 10 years. Initially started with investments and auto insurance, then life insurance, homeowners, more life insurance policies as my family grew. Every time you call you get a real person who is in the office, not a call center! You aren’t just another policy number, you’re a valued customer! I could not recommend Greg’s office more and always tell people to check it out when they ask about insurance."
