Adam's love for the automotive business might have originally come as a surprise to many as he was the first member of his family to choose this career path.

Company Team


Executive Officer and Brand Manager 

Jeffrey is a guitar player from Pinson, Alabama. At least that's where it all started. After spending several years on the road and in studios producing projects for a number of up and coming artists and songwriters; He realized his ultimate passion in life was helping other people achieve their dreams and translate their vision into reality. This realization urged him toward a series of entrepreneurial opportunities in the fields of creative design, branding, and real estate development. It was during this season that he first met and began forging a close friendship with the McSweeney family. An auspicious encounter that would eventually lead to an invitation to join the McSweeney Holdings biz dev and management team. Driven by a personal faith in Jesus and a practical philosophy that "It's the value you add, problems you solve, lives you touch, and the friends you keep that matter most in life" there is nothing that Jeffrey enjoys more than personally connecting with McSweeney Designs' team members, clients and strategic partners. His daily focus is helping to provide creative coach design solutions that enable people to successfully travel between the worlds of business and pleasure and maximize the value of their time with family, friends, and business associates. Jeffrey lives in Helena, Alabama with his beautiful wife & better half, Lisa Hunter and their 3 children Brooklyn, Blake, and Will. With a packed work schedule and active family life there is not a lot of time left for playing guitar these days. But with so many other reasons to be grateful he doesn't seem to mind at least not much anyway. His weekend hobbies include watching his boys play ball, Cars & Coffee, and whatever his wife Lisa says.

Jeff Shook

Product Design Engineer

Jeff is an all around ace product design engineer with over 16 years of experience. He studied engineering right out of high school before joining the manufactured housing industry where he worked in supervision. He later transitioned to the RV industry and through opportunities, diligent work, and study landed the job of design engineer for one of the largest and most highly regarded luxury RV manufacturers in the business. Jeff has worked in the manufactured housing, recreational vehicle, and construction industry... but that's his vocation. Rumor has it that his avocation is what we really need to be talking about. The word on the street is that Jeff can belt out some mean karaoke action in some of the finer music halls around town. When not designing the next masterpiece or bringing the house down with his passionate vocals... Jeff assumes his low key disguise as a mild mannered suburbanite and all around groovy dude. He has two children he enjoys spending time with. No word if his kids are aware of his rock star skills.
