Because I just ordered the policy and so far all’s good!
Shane H. was incredibly informative. This was my first time buying a home and having to also look for my own car insurance and he explained everything to me! (even multiple times if I asked!!) He was so kind, and I will absolutely recommend other to work with him!
He’s very knowledgeable and quick with information.
It was a quick and easy process
Was accomplished quickly and equitably
Lukas was absolutely great... Explained everything in detail to me in terms I understood. Made it an easy transition from NY to DE
