About Rollin Diesel

Rollin Diesel is a family owned and operated business that was formally founded in March of 2018 as a part time operation. What started out as a hobby for owner, Brandon Mattingly quickly turned into a passion.

From working on the vehicles of associates in his garage with a friend quickly transferred into the full-blown operation you see today. Brandon made the decision in July of 2020 to make their dreams a reality and turning the business into a full time operation.

It was not easy to get where we are today as there were many stepping-stones(including the tragic loss of one of the founding members) but, we are thankful to each family member, friend and customer who helped turn our dreams into reality.

Brandon - Owner | 215-588-5813 | rollindiesel@outlook.com
Meet the Owner! The man behind the vision for Rollin Diesel is owner, Brandon Mattingly. Ever since he was a child Brandon loved working with his hands and figuring out how things work. It was an easy choice for Brandon to attend Bucks County Technical High School where his focus was automotive technology. To complete his school requirements Brandon completed many co-op opportunities, to which he is thankful for each, as they helped him pave the way for his success today. Although throughout his employment history Brandon always kept busy with side jobs, he knew it was time to settle down. As Brandon took a dive into the workforce in attempts to find his perfect fit, he landed at McCafferty Ford in Langhorne as a mechanic. It was during this time Brandon learned of his true love for diesel, as from the next bay over, he admired the work of a co-worker and friend, the late Walter S. Brandon took a job with a private company to be more hands on to a specific fleet, where his experience only grew his diesel knowledge and led him to an opportunity with SEPTA, where he worked on a majority of the company’s fleet from trucks to heavy equipment. It was not long until SEPTA noticed his potential and offered him a management position.

As Brandon was moving up in the company, he could not help but feel something was missing. With the weird hours he was working, Brandon continued to complete side work with the help of some friends and cousin Mike. As the work continued to come, the side work turned into a full business before their eyes, which they named Rollin Diesel in 2018. The work continued to come which required they rent some space which quickly outgrew, it was at this time, in 2019 (as Covid started to make its debut) Brandon and his team decided it was time to turn their side gig into the American dream and the business began its full-time journey that people come to rely on today.

Brandon prides his company, the same way he prides himself, on honesty and loyalty. You will find that Brandon not only holds employees to a high standard but, himself and the company are too. Rollin Diesel prides itself on being a one stop shop and being able to fix any issue thrown their way.

Walt: 1985-2022 | Gone too soon but never forgotten
Although he passed away due to Covid complications in January of 2022, Rollin Diesel WOULD NOT be the shop it is today without one of its most valuable past employees, Walter. The son of an automotive shop owner and mechanic, you would say that he was born into the trade. Walt, who met Brandon at McCafferty Ford of Langhorne, was a Ford Master Tech who made a brief transfer to Septa, before making his way back to Ciocca Ford. The person who helped lead Brandon to his passion for diesel quickly became more than an employee but a friend and one of the same people who helped push Rollin Diesel to the next level by becoming its first ever full time employee. Giving up the dealership life to help a friend reach his dream, just shows the kind of person Walt was. There was nothing that Walt was given that he was unable to fix. His absence has left a hole in the shop that can never be filled and he will always be remembered at Rollin Diesel.
