We are a small company in south central PA. For years we were with SWIF. Eventually I tried Amerisafe for a year thinking it would be a good option to get away from SWIF, but it was so expensive and the down deposit was something like $7,000 and they didn't even apply that to the premium throughout the year, they just held that money and then it took forever for them to return it after we switched to another company (even though I made every payment on time, had no claims, etc.). BCF Insurance out of Lancaster is our broker/agent, and we currently have our WC policy with a company called Encova - it is VERY affordable (our MOD is something like 0.8). Looks like BCF does work "across PA" so it may be worth contacting them:
