American Advantage Cornerstone Insurance Services LLC

Jeff has done such a great job for me and my businesses! It all started by finding a $17000 overpayment caused by a previous agent. Man knows his stuff!

Jeff is an awesome guy, glad to know him and have im as my insurance agent! Will go above and beyond for his clients!

I have had Jeff Bergum as an insurance agent for my business for over five years and was happy to move my business over to his new agency. Jeff is personable, thorough and very efficient. As a client, I have never had trouble reaching him with questions about my policies and he follows up with information in a timely fashion. I never get the hard sell from Jeff and only receive sound insurance advice that meets my needs.

I live almost two hours away from this location but don’t let distance stop you from switching to the best Insurance company out there. Jeff made it a very smooth, easy, and quick process to switch over my services. Thanks to technology we were able to switch over my services with out even leaving my house. He e-mailed me all the paper work I needed and was there for me anytime I had a question. Very knowledgeable and truly cares about finding you the best quality services at a reasonable price. He is very easy to get a hold of and makes himself very available to you. I have been a client of Jeff for 8 years and wouldn’t have it any other way! He was able to bundle mine and my fiancé’s home and auto insurance saving us some serious cash with out jeopardizing quality!

Not only is Jeff an outstanding insurance agent, but he is an absolute asset to our community. He continues to go above and beyond for many local businesses, non-profits, and New London's Chamber of Commerce. Grateful to have Jeff and American Advantage Cornerstone Insurance servicing our area.

I had been working for over 2 months with an insurance broker trying to get my policy ready to open up my own trucking company. But them didnt even had a clue of what they were doing even after i gave them a sample policy and rewrite my policy several times. Fortunately i came across Cornerstone Insurance, who were able to get my quote ready acording to my specifications in just 2 days and best of all way cheaper. Now i am able to start working on my own trucking company thanks to them. I higly recomend Cornerstone Insurance for your insurance needs.
