Diamond Transport Inc.




Located in Stockton California, Diamond Transport Inc. is a trucking company specializing in Refrigerated Transportation.

Diamond Transport Inc. was founded in 2004 in Stockton, California, when two brothers, Nick and Dave Atwal, decided to pursue their dream of opening their own trucking company. Both brothers already had deep experience in the trucking industry; doing everything from driving to dispatch to brokering services in the Pacific Coast area and beyond. Just a few years later, Dave and Nick were joined in their business venture by a very close family friend, Gulwinder Singh. Combined, the trio has over 75 years of experience in the transportation and logistics industry; a trait that we pride ourselves on and that not many other companies can claim. On top of years of experience, we hold ourselves to a set of values that ensure you'll get excellent customer service.

  • Always put the customer's needs first; this means going the extra mile to make sure the very best outcome is achieved even if things are going wrong.
  • Constant communication with our customers. This was achieved through the development of quality dispatch software that allows the company stay on top of every shipment in real-time, allowing us to be proactive in communicating information to customers and haulers alike 24/7.
  • Running the company with the ownership group on the front line with customers and our haulers. Knowing the real world first hand has helped us to understand and grow the business reliably and to anticipate and make changes before they are needed.

These basic principles have earned Diamond an admirable reputation for customer service, reliability and on-time delivery. We promise you one thing: Our service is service that you can count on. Diamond has operated on a simple premise that seems so hard for others to achieve. It is simply: "Do what you say you are going to do" That's the Diamond way.

When Diamond first opened, it started with only two trucks. 14 years later, we have a fleet of over 75 trucks and over 100 trailers. Diamond first operated primarily up and down the Pacific Coast, however we have expanded our operations in recent years and now operate all the way to the Midwest in states such as Kentucky, Ohio, Indiana, Illinois, Texas, Missouri, and Georgia. Our biggest lanes are up and down the Pacific Coast, going from Arizona all the up to Washington.

customer testimonials

We have been fortunate to receive amazing feedback from our customers over the years. Don't take our word for it, take there's!  Check out a few customer testimonials below. 



It is with great enthusiasm that I'm writing to recommend Diamond Transport.

We first began working with Diamond Transport back in 2016 and immediately we saw that even with the savings we were now getting on the lanes they were hired to run for us, that we would not have to sacrifice service to get the new rates.

The level of communication and their ability to be dynamic when needed on loads is what really sets them apart from our other 3PL carriers.

From day one I have been able to count on Diamond Transport for weekly dedicated loads as well as spot loads that come across last minute, to be delivered on time and unblemished.

In closing Diamond Transport is service you can count on, and one that I would recommend highly,

We have been using Diamond Transportation every day for over 5 years now and couldn’t be happier!!

The people are outstanding, they do what they say, 100% reliable and they make my job a lot easier. 

Diamond Transportation plays a “Huge” role in the success that DJ Forry Company has been fortunate experience over the past 5 years. 

They are a great partner to have and not sure what we would do without them.

Kind Regards,

I have had the privilege of working with Diamond Transportation over the past 3 years. My relationship with Diamond Transportation has blossomed into one of mutual and professional respect along with friendship. My role at Weber Logistics as  Senior Director, Transportation Solutions has allowed the start of this relationship but the partnership exists today because of a deep level of trust and respect. I can count on them picking up on time, communicating through the process, and delivering on schedule. I hope with this letter you can add them to your list of carriers as I know they will be a valued addition.

Thank you
