Meet The Owner

Hi, I'm Allen from Monster Muffler. I had graduated in 1983, and after 6 months of odd jobs, my dad and his business partner, Andy, decided to open up a muffler shop in 1984 on Avalon. Andy taught me about exhaust, and I picked it up really quick. Andy decided to move on which left me with the responsibility of the business. Now keep in mind, I was only 19 years old at the time, so there was a lot of weight on my shoulders, and thankfully my hard work paid off. I was working at that location on Avalon for roughly 6 years, when the opportunity arose to purchase a new and much bigger shop on Wilmington Blvd. I took the risk and purchased the property, leaving behind my old shop with the hopes of building a much greater, and more successful one. I think it's safe to say the risk paid off, I have owned and operated at this location for over 27 years. I am thankful for my service to the area and will be for many years to come.
