A LOCAL INDEPENDENT AGENCY
Insurance feels easier when you have real people helping you through it.
Insurance should not feel like a maze of forms, policy language, and call centers. At M.K. Sullivan, clients work with a local team that takes the time to understand their needs, explain their options, and help them make practical coverage decisions. Whether you are insuring your home, car, family, or business, our goal is simple: help you feel protected, informed, and taken care of.

Responsive Service
Questions, certificates, claims, billing issues, and policy changes should be handled by people who know you.
Local Experience
With more than 30 years of experience, we understand the needs of families and businesses across the region.
