Clients Come First, Always

In each market, we have a team that works with you regularly because we build close, long-term relationships with our client. We serve many clients for life. Not many companies can make that claim.

In 2001, we did a voluntary safety recall on a battery equalizer — and we didn’t lose a single client. We did what we said we were going to do, worked tirelessly to do it, and our clients said we were there for them when the chips were down; every single client remained with us and we forged even deeper relationships with clients that continue today.
