I stumbled upon DG’s completely by accident after breaking the rear windshield wiper arm on my Jeep and trying to find somewhere to fix it that wouldn’t cost hundreds of dollars. Jess at DG’s went above and beyond checking suppliers, and wreckers, and even Amazon to locate a part that would work without costing an arm and a leg. I’ve been going there ever since. I drive from Kitchener to Listowel because these guys are worth it. They do good work, aren’t overpriced, don’t recommend repairs you don’t need, and I get to hang out and play with Oscar while I get my service done. Only thing more I could ask for would be more comfortable chairs. Haha.

Michael Carlson Nov 12, 2025

Great service and friendly staff . They keep me informed of there progress and no surprise repairs Thanks again for the great lift

Garth Collins Nov 6, 2025

I am very happy with the service I received. Jess is very nice and answers all your questions or concerns. The team there are very thorough in the work they do and take the time to explain anything you need. This is a friendly atmosphere of great mechanics and all around service. Prices are very resonable.

Yvette Moreel Oct 31, 2025

Brought my truck here after it spent months at another mechanic and didn’t get fixed. Every part of this experience was fantastic. Lots of communication, the work was perfect, and the knowledge the staff holds is very noticeable when it comes to what parts to use

Adam Faria Oct 29, 2025

These guys are amazing, after hours calls, quick and fair

Ben Hanlon Oct 29, 2025

The best shop to deal with everyone is super knowledgeable!

Kendra Wilson Oct 23, 2025

Great customer service, and a well knowledgeable team over at DG pro, I got a lift kit put in there and had issues with incorrect parts with the lift (I ordered wrong) and they made sure and did everything they could to make sure it was done correctly and nothing was wrong with ordering the correct parts needed, would recommend to anyone for all there repairs and cosmetic needs, thanks again DG PRO!

Ben Jacklin Oct 15, 2025

Joe Carter Oct 8, 2025

had Dustin work on my engine 2006 f350 diesel 2 years ago and it never worked this good. excellent work done. last week i needed some more tlc and even though it cost me a small fortune (they were reasonable , fair and honest) they found many items requiring attention and repair. very pleased with the work done : new manifolds, multiple front end repairs, rear brakes with calipers and the oil change and vehicle inspection

tim togeretz Sep 25, 2025

Thank you Pro Tech team. I had a very positive experience. Tyson and Jess were excellent communicators and honest and forthright. The wisdom, experience and knowledge of Dustin, Tyson and the mechanics is exceptional. The team has a unique and inspiring corporate culture where pride in workmanship and service excellence is a top priority. The quality of workmanship is exceptional. Thank you again Robert

Robert White Sep 18, 2025

Came in for a simple oil change and tire rotation and I will definitely be back! Tyson made sure I was helped quickly and suggested future maintenance issues to help me down the road. Excellent customer service all around

Justin Timm Aug 14, 2025

Super helpful staff, both Kendra and Jess. I also had an incredibly informative discussion with Dustin regarding my truck. This is the type of professional team I like to deal with! Thank you!

Eric Scetto Aug 14, 2025

Got new tires and an Iron Man kit installed on a 2021 Subaru Forester. Kendra was great. She went back and forth with her tech, suppliers, and me multiple times while we were deciding on what brand, width, and profile of tires to go with, ...and went on over way to watch some videos on the types of modifications I'm planning to do for the car in the future, and the technician who helped me did a great job installing the lift. I'll definitely be coming back.

Jack M Jul 31, 2025

new client to DG's and I have to say I am quite happy I found them. Service Advisor Jess goes above and beyond. I really can't say enough good things about the level of service she provided me. Unbelievable. She was in constant communication with me through out my project and did anything and everything anyone could hope for. DG's started off on a really good note and made me feel like they would treat my truck like their own. I decided to do a large project with them(lift) and they did not let me down. Amazing job. Jess, Tyson, Dustin and the boys in the back. Thank you! trust is a big thing in this business and you all have earned mine. We have more to do :)

William Risnyj Jul 27, 2025

Originally brought my 2016 Ram 2500 in for an oil leak and various other upgrades. Big thank you to Jess, Dusty and the mechanics at DG’s. Jess and the team worked with me closely, accommodating my budget and giving recommendations on how to proceed further. They always maintained good communication, keeping me informed on the progress and any other hiccups along the way. Dusty is incredibly knowledgeable & smart - who helps make sense of the repairs & upgrades. It might cost more, but it’s worth it for customer service, the vehicle report & piece of mind that you and your vehicle are being looked after by the best in the area! Don’t think twice about it, bring your truck to DG’s!

Logan Forbes Jul 24, 2025

It was my first time using DG Pro Tech's services for a vehicle inspection and I have to say it was one of the most thorough explained visits I have ever received! Greeted by the cutest little doggy tech, they were very accommodating to my needs and Kendra was on top of all the updates! She was super helpful and I think deserves a pizza party in her honor! I will for sure be recommending DG Pro Tech to anyone who needs car maintenance! I left feeling confident and satisfied in their services provided :)

Julie Drouin Jul 17, 2025

Wish I would have come to DG's sooner, everyone is exceptionally knowledgeable, honest, and professional! Great Team to deal with! I brought them my old Dodge Cummins and felt 100% certian the work would be completed the right way the first time. Thanks again!!

RENNICK 666 Jun 13, 2025

Jess at Pro Tech is super great and easy to deal with! Highly recommend, great service!

Dani Evans May 23, 2025

David May 8, 2025

These guys were great to deal with, honest and super helpful when I was on a short timeline. Would recommend

Nic Hamilton May 3, 2025

Super happy with the service provide. Communication is 5 start

Tommy Boy Apr 23, 2025

I’ve got a 2012 6.7 that’s been bouncing around to all the shops in my area and after about a year of not having any luck with the work done I finally discovered DGs. Wish I found them a lot sooner. Within no time they had the motor swapped and truck ready for work. They have the best form of communication I’ve ever received from a shop. Loved everything from the quote to the final bill. Had everything done within a reasonable time with no excuses for anything. So, if you’re torn apart about where to take your truck I’d highly suggest going to them. I will definitely be using them for all my trucks needs from here on out.

Adam Khiawpuang Mar 4, 2025

Another great experience from Dustin’s team. Will keep coming back!

Kiel Magis Feb 7, 2025

Thanks for getting my eco diesel up and running after the dealer made a mess of the valve cover injector egr bracket and other stuff while trying to unstuck a leaky injector. Saved me A bunch of money from the dealer quote which I didn't feel they could actually deliver on given the mess they already made.DGS provided a detailed quote and kept me updated throughout and only did what was needed.

Mike B (Magyvered) Feb 5, 2025

Brought my ram 2500 in to get some work done. From start to finish Tyson and his team exceeded my expectations, the quote was fair and the work was a performed quickly. I’m very happy with how my truck turned out. Thank you to Tyson and his team I will recommend all friends and family in the future to bring their vehicle here if they require top notch service.

Daniel Griffin Jan 14, 2025

Glad I made the trek, in a snow storm, up hill both ways!.. best knowledge, service and Ill be back again!. thanks all!

morgan Jan 4, 2025

Very knowledgeable ower and advisers. Top notch mechanics

Jason Schneider Jan 4, 2025

Highly recommend DG's Pro tech. Had our Duramax in (Preventative maintenance obviously since its GMC so it wasn't broken down) and the entire team was amazing! the owner even drove to pick up a part that wasn't in stock so we could get it complete and go on with our day. Their system is very organized and communicated very well with their customers which is very important and made the process that much more enjoyable. We will only be going to DG's pro tech from now on for great service, communication and for the knowledge Kyle the tech had which is very rare to come by these days. Highly recommend, 5 stars.

DAKALM Dec 30, 2024

Very friendly staff, mechanics go the extra mile on helping their customers, communicate clearly and the best part, is that they don't upsell as they are people too and understand costs. I will definitely recommend this garage

Ryan McLean Nov 20, 2024

I used dg protech to do a substantial amount of work to my truck. From start to finish I was extremely happy with my experience. Dusty and the entire DG team are absolutely stellar at what they do. I'll definitely be using them for all my future mechanical needs. I would not hesitate to recommend them to anyone.

Ron Hirschfeld Nov 20, 2024

What a great group of people from the mechanics to the receptionist, everyone is very friendly and knowledgeable. The diagnostics are off the chart. I would highly recommend if you want your Vehicle running tip top shape, Bring it into DG’s

BrownGoDeep Nov 1, 2024

DG's recently performed an alignment on my Mercedes E400. Their alignment equipment and knowledge were top-notch. The alignment results and nature of adjustments were explained well. Very pleased with the service and value, would highly recommend.

Simona B. Oct 26, 2024

Fantastic ! The quotes are written out so clear and upfront. For those things that I didn't quite get, Dusty called and explained everything. The video's on the website are so informative. I only new the names of the brake parts, to see what is what when they are looking at them to determine the wear is just great ! Thank you to all the hard working mechanics and to Jess who answered all my pesky emails !

Jen Janes Oct 8, 2024

Awesome shop! Very friendly group of people, good website, and I love their high level of communication. Just moved to Listowel and will using as my go-to local shop.

Joseph Oct 1, 2024

They explain in detail about the problem with the vehicle and what they did to fix it. I have finally found a trustworthy business I can trust my truck with and highly recommend them to anyone that is looking.

Very intelligent staff and technicians! 100% recommend !

Kyle Steckley Jun 12, 2024

I’m new to Listowel and was looking for a car repair place. DG’s was recommended. They were friendly, professional and the cost was less than I would have paid in the city! They even dropped me back home and dropped off the car when the job was done! I’m very impressed!

Theresa Karn May 29, 2024

Always an excellent experience at DG's. The service was top-notch, and Tyson was fantastic—professional, knowledgeable, and incredibly helpful. Highly recommend!

Justin Hergott May 17, 2024

Excellent staff and technicians , they went above and beyond to get my Ram 1500 running properly again after 2 other garages failed to do so . They even gave me a loaner vehicle to use while mine was in the shop ! There is a reason I didn’t mind driving an hour to use their services. They will take care of all my vehicles needs in the future . Thank you DGS Protech .

Peter Racz Enterprises May 10, 2024

Excellent advice and great work. Took the time to explain everything to our satisfaction.

Lori chessell May 9, 2024

DG's Pro Tech did some work on my truck and did a great job at a very reasonable price. They also completed a complimentary inspection on my truck and alerted me to things that needed attention and eased my mind about things that don't. Dustin has probably spent close to an hour total on the phone with me personally explaining things to me, which I really appreciate. I also had great experiences talking to Tyson and Megan. I'll be back for future work that I can't handle myself.

Myles Brady Apr 12, 2024

Bringing my truck here was the best decision I could have made. Its a few years old, has a lot more KM on it, but my truck has been with them since new and its in better shape now than RAM ever thought it could be. Vehicles weren't designed to be taken care of THIS well. DGs die hard for life.

PLATINUM FRAMING Mar 9, 2024

Amazing service right from the beginning, super friendly, incredibly knowledgeable, and did what ever they could to help me in a pinch.

Jamie Santos Mar 6, 2024

No better ford diesel tech out there hands down
