Kristin Watson

After a bad experience at pepboys, I was hesitant to trust another mechanic. However, Upstream diagnostics has restored my faith in automotive care :) They were transparent about the repairs needed, kept me informed throughout the process, and delivered quality workmanship. Top-notch service all around!

What Our Customers Are Saying

Ryan Ceianti (a month ago)

Highly recommend this shop for any issue. Dameon is by far the most friendly and honest mechanic I’ve met in my life. I brought my Mercedes Benz in for a suspension and sensor issue and he took the time to explain all the issues in detail to me, and kept me updated throughout the process so I knew exactly what was going on. He was able to complete the work and get my car back on the road even sooner than I was expecting. I’m looking forward to when anyone asks me if I know a good mechanic so I can send them his way. Efficient, honest, friendly, and great care for detail. All you could hope for in a mechanic. 10/10 for this shop.

Stevon Joyner (5 months ago)

Damien was great about answering the phone in a positive manner and making me feel valued by addressing all my questions concerning the progress of my vehicle's repair as well as what to do to keep the engine running properly. He also educated me about the power trans on my vehicle. I have no issues about becoming a return customer. Thank You & Best Wishes Always, Stevon.

Peter Hissey (2 months ago)

We brought our Honda Odyssey in for a routine check up. We were tired of working with the service department at the dealership who always flagged 15 “minor” things that they recommended we do for the car. I am not a car savvy person so it felt like I was being taken advantage of. We looked for someone we could trust to do good work, keep our car ahead of any major issues and be responsive. We had a great experience with Dameon at Upstream Diagnostics. We booked an appointment quickly, dropped the car off after hours, got a call from him the next day with what he found, and picked it up midday. It was a great experience and we will be back!

Molli Ferrarello (4 months ago)

Dameon is professional, friendly, and trustworthy. I brought my car in because my AC stopped working. He gave me an accurate estimate of how long it would take, diagnosed and solved the problem quickly, and charged a fair price. Will definitely be returning to Upstream Diagnostics for any future issues or maintenance!

Jocelyn Wilson (2 months ago)

I have NEVER, in my 15 years of owning a vehicle, worked with someone so amazing! Dameon is the most honest, professional, reliable, personable, and caring mechanic in all of Pennsylvania. I genuinely can’t imagine working with anyone else in the future!!

Brianna Mullins (a month ago)

If you have CarShield, go here!!! Damien was very friendly, helpful and thorough with my car; he has gone above and beyond. Oil changes can also be done here, I will be back. Thank you!!!

Carlos Smith (6 months ago)

Upstream Diagnostics is top rate. The mechanic is the best, he gives you step-by-step information on what he’s doing to your car. He will outline and diagnose what has to be done to the car. He is really passionate and cares for the cars he works on! He put an engine in my car and has a client for life! Great place!

Jesse Rougeux (10 months ago)

Finding a trustworthy and skilled mechanic is like finding a rare gem nowadays. That's exactly what I found taking my car to Upstream. I would drive to great lengths to have Dameon work on my car. What sets him apart is his genuine care for his customers and their vehicles, and he takes the time to explain the intricacies of the repair process. He followed up with me after I left the shop, which is very reassuring knowing I can ask questions and get tailored advice whenever I need it. Pricing is always great, no hidden fees, and the peace of mind knowing Dameon went above and beyond to make sure the car leaves the shop in top-notch condition. Upstream is truly a hidden gem, and I constantly recommend him to family and friends.

Anthony Hochstuhl (9 months ago)

Dameon was very professional, got the job done, and has my car looking great.

Elizabeth Wolf (9 months ago)

Dameon is the best. He's extremely knowledgeable and helpful, but most importantly, he is entirely trustworthy. It is so hard to find someone who will do good work and solve the nagging problems with your car while not taking advantage. I fully recommend him/Upstream Diagnostics to anyone in the area.

Kyla Sharpe (3 months ago)

Spoke with Dameon. He was very polite and easy to work with. He answered all my questions and took care of whatever I needed.

Eric Vaughn (9 months ago)

My experience with Damien is I loved how knowledgeable he is with cars and how far he will go to fix the problem. It just feels good to have a good mechanic. He’s new to the neighborhood and I wish him well.

A Stanciu (9 months ago)

Best guy in town! He fixed my car after the dealership only took my money for nothing! If you have problems with your BMW, come to this guy. From what I've understood, he does all cars, not only BMW!

Melissa Nance (10 months ago)

Awesome experience! Dameon is great! The best in diagnosis. Would recommend to anyone.

Elizabeth Ray (9 months ago)

Did an excellent job on replacing my engine. Car sounds and works way better.
