If you are truly interested in getting into a CDL career I would wholeheartedly recommend Prime Inc. Many disregard them as just another mega-carrier but my experience thus far has been great!
My last employment before embarking on this path was at a gas station/truck stop. I am very thankful that I had the idea/spark hit me to look into it. I had a pretty high paying corporate job after spending almost 20 years in sales/media/personal finance that went all the way to hell enough that a year and a half after making right at 6 figures I was making $14 working 3rd shift at said gas station with no hope in sight of ever getting back to that tax bracket again.
Now I have hope again!
If you have any questions I'll be happy to answer. The recruiter I worked with at Prime is Emily Lemons and my referral code is BENAMC let me know if there's anything I can do to help!
