We care about you! So, whether we are working with you on your home and auto, or your business insurance we take the time to understand what is important to you. We uncover your needs to assure we get the correct coverage to protect you, your family and your assets. We take an education-based approach to make sure you understand the various risks and fit the coverage to you…not try to sell you the same coverage/policy that everyone else may have. We work for and with you.



As an independent agency, we offer you choices. We work with various insurance providers to assure not only that you get market competitive rates, but that we are getting you the best coverage for that price point. Being independent allows us to work for and with you instead of representing the insurance provider. If you were to be unhappy with your provider for pricing or any other reason we can find you competitive coverage/rates with another provider and you still work with the same agent that fully understands your situation.



We are licensed in many different states, and work with you to find the right fit for whatever your needs. We offer our services for personal, business, life, workers compensation, commercial auto, umbrella, disability, long-term care, builders risk, and many other lines of insurance. We also work with other professionals outside of the insurance realm so that we can be a partner and advisor for our clients.



Coverage comes in many shapes and forms. Many people get very concerned when it comes to covering their stuff. The problem is they often fail or neglect to cover one of the most important things…themselves. Make sure you take a comprehensive look at all the coverages you may need. We are here to help you understand your options, and the various products that protect you, your family, your business, and your assets.
