Customer Reviews

October 28, 2020

Being new to New Hampshire I never really gave any thought to changing my auto insurance. I figured I was just changing my address, but with a new state came a whole new policy. It ended up being more complicated than I realized. When Portsmouth Atlantic contacted me I was glad to know that there was someone local making sure my auto insurance was being handled correctly and helped me get the forms that I needed in.

I was pleased with the fast response from my initial email. We were looking to switch companies. My email was answered promptly, and shuttled along to my present, very conscientious agent, Jessica. Thank you for your great service!

October 28, 2020

I had questions to which Cathy had the answers and we were able to correct my billing on the spot. Feels good to know that I can get quick responses to my concerns. Customer service is important to this company!

Brian and Jon are always quick to respond whenever I have a question or want a quote for a new policy. They are thorough, detail oriented, and knowledgeable!

I have done business with you for quite a few years and I am big on customer relations. No matter what questions I ask or what I need done, I can always rely on your group. I do not want to single one person out but 90 percent of the time Cathy Merwin helps me, so please let management know that people like Cathy keep me at Portsmouth. I love doing business with your group.

The most valuable service Portsmouth Atlantic Insurance offers my family is the access to a knowledgeable and experienced staff. Sometimes we receive a lot of technical paperwork regarding our policies, but I know a PAI representative is a phone call away and will help us navigate any questions or concerns with courtesy and professionalism. I enjoy the opportunity to refer PAI to friends, family and colleagues as often as I can.

October 28, 2020

Love this insurance company. They are always right there to help with any changes I need to my insurance policy, (and there have been many), and they do it in a timely, efficient manner. Pricing is very competitive, too. I highly recommend!

October 28, 2020

Jessica was extremely helpful and patient as we were learning what we required for insurance and gave us so many options to cater to our needs. I would HIGHLY recommend working with Jessica and Portsmouth Atlantic Insurance to anyone who is in the market.
