The shop
Born and raised in Welland
Tony Berardocco is a 310S Red Seal technician with Ford and GM dealer training and years in independent shops. He opened Berardocco Auto at 230 Colborne St on August 31, 2026.
Tony was born and raised in Welland. He trained at Ford and GM dealerships, where the diagnostic and programming work happens, then spent years in independent shops seeing the other side: customers paying dealer prices for jobs a good independent could do, or getting parts replaced on a guess because the shop did not have the tools to find the fault.

Do you only work on Ford and GM?
No. Ford and GM are where Tony's dealer training is, and the shop works on other makes as well. If you are not sure, call with your year, make and model and we will tell you straight.
Why go to an independent instead of the dealer?
Tony trained at Ford and GM dealerships and does the same diagnostic and programming work here. You talk to the technician who worked on your vehicle, and you pay independent shop rates.

Tony tells you what he found, then writes up the parts and the labour. You say yes or no.
