Why we love it here
At IBP, we invest in all of our employees. That means robust benefits (medical, dental, vision, short- and long-term disability, accident, and critical illness, company-paid life, and retirement plans), paid time off, and the IBP Foundation, which offers scholarships, emergency assistance, and volunteer matching for everyone in the IBP family. We pride ourselves on supporting our teammates’ quest for additional training and certifications outside of what we provide by paying for those opportunities.
