The short answer is yes, it may be good to have insurance with more than one company.
If you are eligible for insurance coverage under an affinity plan such as a plan that is only available to employees or retirees of a specific business or military personnel , veterans or retirees, you should investigate the coverage and rate of this plan. It may be a good idea to have insurance under that plan and also to have insurance with another insurance company. For example, affinity plans often offer insurance to individuals and families but may not offer insurance to homeowners and so if you are eligible for the affinity plan and also a business owner you may choose to sign up for the affinity plan for personal needs and then sign up for business insurance with another company.
Ask our insurance agency whether you should consider having insurance coverage with more than one company.
