I shopped around and no one even came close to saving me as much money on my first home insurance policy as Jon at Portsmouth Atlantic Insurance! Not only that, Jon patiently answered all of my detailed questions, and helped me to understand what different options I had, and kindly customized the perfect policy for me and my new home. Thank you so much! Looking forward to working with you folks for a long time!

Portsmouth Atlantic Insurance has been professional, transparent, and is always looking out for my best interest. I never feel the need to shop around or look for a better deal as I know they’re always looking for the best coverage at the best price.
Christopher C., Rollinsford, NH
Jon and his team are absolutely amazing. They are polite, courteous, knowledgeable, informative, very communicative, and get things done in a very timely manner. When talking with Jon he made it feel like I was talking with an old friend. I now understand why my friend recommended Jon and his team for my insurance needs. I highly recommend this great group of people.

Initiative was taken by Rebecca to investigate companies that would supply insurance, with increased coverage, at a reduced rate. Personalized service most appreciated.

Jon Merwin is the man! Worked with him for awhile now and should have moved over to Portsmouth Atlantic sooner. Insurance is one of those things in a busy life that you rarely think about. It’s great to have insurance with someone I trust!

Jon was fantastic! I was struggling to find homeowners insurance as I was purchasing a very old home that needed work. He found us better coverage for lower premiums for both home and auto insurance! Thank you!
Elyssa S., Concord, NH
We weren’t the easiest client, since we had multiple policies to transfer from our previous carrier. Jon took the time to understand our needs, find the best options, and make the entire process smooth and straightforward.
Cindy P., Hudson, NH
They are a people/customer oriented agency. Whether it be the owner or one of their valued employees, our question or inquiry is always promptly answered whether it be a homeowner or automotive inquiry. They have found us very competitive rates on both and we know we are getting the most value for our money from well established insurance companies. We are both more than satisfied to be with Portsmouth Atlantic Insurance.

Portsmouth Atlantic does a remarkable job reviewing our coverage each year, including a changing cast of college-age drivers The insurance market is in considerable turmoil, and having your expertise in the negotiations is incredibly helpful and reassuring.
Charles F., Boston, MA
My agent was super helpful, going above and beyond to find me a better deal than my current insurance. Email responses were quick even on their off days. Would highly recommend!
Eugene H., Middleboro, MA
Exceptional service! I requested online quotes for homeowners’ insurance with six insurance agencies and not one response. Our closing date was approaching, so I tried again with Portsmouth Atlantic, and Brian contacted me within hours. He found us a robust package, more than I was expecting, given the unique aspects of the property. Within a day, we had coverage! Brian’s responsiveness and professionalism was outstanding; they are a family-owned business and are extremely knowledgeable. So glad to have found them!
