About Us


Steve Proia is the proud owner and founder of Authentic Auto Body & Collision LLC. Prior to establishing Authentic Auto Body, Steve started his auto body career at Minuteman Career and Technical High School located in Lexington. Since then, Steve has gained an extensive amount of experience at every angle of the trade from working on the floor as a technician and painter to then becoming an appraiser in the office and managing the techs on the floor.

As Steve became more experienced and knowledgeable about the industry, he quickly came to realize that most body shop owners shared a commonality, which was that they placed a higher value and level of concern on dollar figures than they did on customer safety and quality repairs. Knowing what he did, this didn’t sit right with Steve and knew that someday he would break the chain of auto body shops not only using cheap parts and materials, but also cutting corners on safety items to save the insurance company money.

Today, Steve can proudly say that at Authentic Auto Body, the focus is and always will be first and foremost on the customer. Steve hopes to change the face of the auto body trade and create the type of experience where his customers are known by their name, not just another customer.

Steven and Gabrielle have three children, Vincent, Alessia and Arianna and love being part of the Holliston community. They looking forward to creating lifelong relationships throughout the Holliston area as well as surrounding towns in the many years to come.


Authentic Auto Body & Collision is truly a family owned business. Alongside Steve, you can find his wife Gabrielle in the office who is an enthusiastic and highly driven member of their business.

Prior to Authentic Auto Body, Gabrielle attended Merrimack College where she graduated with a Bachelor’s Degree in Human Development in 2015 as well as a Master’s Degree in Management in 2016. Gabrielle has worked in a variety of industries that offered her a wide range of experiences and interactions. Through those experiences, she discovered her talent and passion is in customer service and business development.

Her role at the shop is comprised of any different areas related to the business. She assists Steve in the office dealing with the insurance company primarily when it comes to paperwork, rentals and payments relating to claims. She is also responsible for maintaining the day-to-day expenses and finances involved in the business as well as the Human Resources portion (ie. onboarding new employees, implementing policies and ensuring compliance, handling health dental and 401k benefits and lastly, event planning).

She plays an instrumental role in assisting Steve with the business operations involved in this family owned shop.
