Monmouth Auto was founded by Marc Di Piero in 1999. He wanted to be able to give customers someone they could take their vehicles to and TRUST. Marc was best able to do this by opening his own business. Eatontown and it's residents responded with great enthusiasm.  Monmouth Auto Diagnostics, Inc. took off better than expected!! Now here we are in 2020 and while there have been many changes over the years, one thing hasn't changed: Marc's desire and ability to provide trustworthy repairs at the best cost possible to his customers.
