"Whenever I have a question or issue, I can speak to an agent or Mr. Keller and get an answer, or am kept advised of the process until there is resolution. We have been with State Farm for 55 years, in Michigan, California and are pleased we found this agency in Maine."

"The people, particularly Dennis himself make it a pleasure to do business. When you need help, they are the first to serve their customers with a smile, positive attitude and caring nature. They carry that caring attitude into the community around them. Could not speak any higher of Dennis and his staff."

"Harry Buttery was super helpful, and knowledgeable with helping me get quotes on home and auto. He was able to do so much more than what I currently had, and got me the best rates. Very friendly and great customer service!!"

"When shopping for life insurance, finding just the right company was overwhelming. There were so many options online, but I didn’t understand all of the details. So I went into the office and spoke with paul (and Dennis another time) to have my questions answered. They explained everything easy & simply so we agreed on a policy and I never thought about it again. Until it was time to collect on the policy. In those moments of grief and the whirlwind of thinking and planning services I couldn’t imagine having to deal with one of those online companies or waiting on hold for hours to talk to one of those 800 numbers. My claim was handled quickly and easily, and with zero stress on my end. I never once had to think about anything regarding insurance. Literally I gave a death certificate and signed a paper and that was it. Check went in the mail within a day or two of that. And that sealed the deal for me. I will always use Keller State Farm for everything I need in the insurance world. Because In a moment of stress I want someone local, calm and competent so I don’t have to deal with “one more thing”."

"I spoke with Harry Buttery, as my wife and her parents have been with Dennis Keller and State Farm for many years. We just got married and I wanted to take the advantage of combining our policies. Harry was extremely professional, took the time to explain the best options for my wife and I. I work for Enterprise Holdings and have dealt with many insurance companies, and this was for sure pure honesty and compassion. At the time I was working and he even let me put him on hold (more than once) to let me do my job and still stayed on the line. He was able to combine and get my wife and I many discounts, as many insurance companies don’t explain how to get the discounts. Thank you Harry and Dennis Keller for making me feel as if I have been with you for years! 😃"

"The team at Dennis Keller-State Farm are knowledgeable, friendly and compassionate. Harry Buttery assisted my husband and I with updating our Homeowner's policy. His customer service is outstanding! He gets really invested in providing the customer with the best coverage to meet their needs. He's exceptionally friendly and welcoming. It's as if you're catching up with an old friend. I've been their client for 30 years and wouldn't take my business anywhere else. Local agents serving local people!"

"Dennis Keller and his team at State Farm Insurance wrote the book on exceptional customer service, so there's never any question our insurance needs are in the best hands. Dennis always goes above and beyond to ensure our peace of mind when it comes to protecting our financial future, our home, and our vehicles. Harry Buttery, whom we just had the pleasure of working with, shares that same commitment to exceptional service. Harry took care of our recent car insurance transaction quickly, courteously, and knowledgeably. He made the process of insuring our new vehicle not only hassle free, but fun...not an easy feat!"

"When I called my State Farm agent about damage to my home after a fire, he came over within hours. He answered all my questions and made a couple of phone calls to put my claim in, and to get the clean up started. For five months now, the communications between the agency and me have been great. My family is back home again. I am so HAPPY."
