Our family was looking for new home & auto insurance. Mars Insurance was recommended by quite a few people. My husband also uses Mars for his business, so we contacted them. We had a special circumstance, but Mars did a great job going to bat for us and finding insurance to fit our needs. Our agent, Andrew, communicated with us every step of the way and was always available when we had questions & concerns. We will definitely be using Mars again and highly recommend them.

Our agent, Richard, was exceptional at every turn. He was always willing to do whatever needed to accommodate until we were totally pleased with our policies. We ended up saving money by switching companies and are very pleased with Mars and especially with Richard's service.not pushy, just knowledgeable and comfortable.

Andrew was a great help navigating us through the tricky Medicare health insurance process. Looking at all options that would give us the best coverage for our personal circumstances. Very helpful, quick to return phone calls and emails. Katie was a great help with our auto and motorcycle insurance also! HIGHLY recommend Mars for all insurance needs.
