 about Phil Altschul, your independent insurance agent.
An independent insurance agent is an individual that does not work for one particular insurance company. Instead, they sell insurance policies from several companies. Working with this
type of insurance agent instead of an agent that is affiliated with a particular brand can be helpful.

​Advantages of working with an independent agent:
  • More Choices
  • Save Money
  • Unbiased Advice
  • Help With Claims​
