Origin Story...
"I became hooked on construction at an early age. I found joy in the smell of real wood and being in the fresh air, the hard work, and the camaraderie of the crew."
AJ Guarino, born and raised in Massachusetts, started his career as a part-time trim carpenter during his summer vacations. By the age of 18, he was supervising and building 40 house subdivisions. After that experience, he transitioned to supervising and constructing apartment complexes. At 20, AJ became a business owner, managing framing and trim crews for other builders and designing and building custom homes in Massachusetts and New Hampshire.
He developed a deep passion for authentic Timberframe construction and high-efficiency homes. To enhance his skills, he studied under master Japanese craftsmen in New Hampshire and later traveled to Japan to learn directly from them. This transformative experience became a cornerstone of his business.
In 1998, AJ moved to Colorado, carrying his passion and expertise from New England. He expanded his services to include remodeling commercial buildings, restaurants, custom home construction, and consulting on commercial and residential projects.
When he’s not on the jobsite, AJ enjoys playing hockey with the Geezers and continues to improve his Kempo Karate skills. He also loves learning new guitar tunes.
