Local Allstate Insurance Agent: Stephen Sullivan

I’ve been an Allstate agent since 2012 and opened our Dover office in early 2024. From the start, it’s been important to me that customers have the information they need to choose the right insurance for their situation.

When I’m not working, I enjoy all that New Hampshire and Maine have to offer. I love spending time with my daughter, playing with the dog (come visit him here in the office!!) and enjoying nature and some fine tunes. As a Dead Head, live music makes me dance and gets me on the road.

My team is comprised of diverse individuals ready to assist you with your insurance-related needs. We value customer service and look forward to meeting and working with you. Call or stop by our agency located at 3 Patriot Dr, Dover, NH, 03820. today.

Products we offer:

Car Insurance Agent in Dover
Car Insurance Agent in Dover
Helps protect you and your vehicle if you’re involved in a car accident. At a minimum, you’ll likely need bodily injury liability and property damage liability to meet state auto insurance coverage requirements and help protect your finances if you cause an accident that injures another driver or damages their property. We also offer uninsured motorist coverage to help with your expenses if you’re hit by a driver without insurance. If you’re looking for coverage to help protect your vehicle, you might want to consider collision coverage and comprehensive coverage, which help pay repair costs if your car is damaged in a covered loss. And, optional coverages, like new car replacement coverage or loan/lease gap coverage help protect your investment in a brand-new car. I can help you choose a combination of coverages that fulfill state requirements and meet your needs. Give me a call to get a car insurance quote today!

Allstate Business Insurance protects your business in ways other insurance might not.

In addition to these basic coverages, the Allstate Business Owners Policy can be customized with additional protection to help cover more aspects of your business. I can help you tailor a policy to fit your small business’s needs. As a small business owner myself, I understand how important it is to protect what you’ve worked so hard to build.
