Owner & Tuner

Alex is the Owner and tuner here at GSD. With over fourteen years of experience in engine tuning, he specializes in the calibration of performance vehicles. Alex started out tuning his own vehicles, and eventually expanded to freelance tuning. In time, demand for his unique talent and knowledge for engine tuning grew, and he eventually opened up Granite State Dyno & Tune in 2011. It’s no secret that Alex has a special place in his heart for Toyota Supra’s, and is currently in the process of overhauling his 1994 Toyota Supra. Alex’s other passion is aeronautical, and once a month you can find him out flying planes for clients. In his free time he can be found at the lake on his boat, with friends and family, and at local car events. Alex is the driving force behind GSD and motivates his team to excel in every endeavor; he is the true backbone of the GSD team.

Rick T.

Rick T.

Fabricator & Welder

Rick is our in house welder and fabricator. When he’s not welding, you can find him facilitating other projects around the shop, or operating the dyno for clients. His passion for automotive began five years ago with the purchase of his first Nissan 240sx, and he currently owns an sr20det powered 1995 Nissan 240sx. Rick began welding at home by saving up for his own welding equipment and practicing on anything he could find to hone his skills and learn the craft. In his free time Rick enjoys dirt biking, working on his car, and spending time with family and friends. With a keen eye, and attention to detail, Rick ensures each fabrication project not only meets but exceeds the standard, constantly striving to perfect and improve his skills.

Auto Body Technician

With over fifteen years of experience, Josh is our auto body and custom paint specialist. With experience in collision work, full restorations, airbrushing, and custom paint, there isn’t much he hasn’t done. If you attend any local cruise nights, you may have seen one of his many masterpieces, perhaps even his own 1970 split bumper z28. Josh has an extensive background in classics and muscle cars, and enjoys transforming and working on anything from domestics to imports. In his free time he enjoys attending local car events, camping, and spending time with family. With his level of skill and attention to detail, he can put the finishing touches on any custom project or build.

Scott started racing Pro Carts when he was 15 years old and after high school, he went to a trade school to learn to be a machinist. When he left the carting scene, he joined the IASCA car audio craze and he would spend his off hours at a local car audio shop learning. He was very much part of the night scene in Manchester, cruising the famous Elm Street back starting in 1999. From there, he landed myself a position at another car audio shop and performance shop, where he did everything you could think of – except engine building and Fabrication (which is where he wanted to be). After having built a 400whp civic in 1997, then a Supercharged S2000 in 2002, he decided it was time to do his own thing. In 2005, he started Ballistic Motorsports. His shop became very well-known nationwide, especially for their work with Honda S2000 and Nissan 350Z. From there he started doing a lot of different things from Weekend Auto-x cars, to Full on RHD conversions, and Top show winning cars. They had full featured cars in many of the most popular import magazines, including the cover of Turbo and Performance. After a successful 10 years, he found myself with no fun time running his own shop and it was time for change. He loves what he does and didn’t want to change his career, so we’ve merged shops! Here here is today, bringing his 20 years of experience, love, and passion for Auto performance to the GSD team.
