A Bit About Me
I graduated from Central Connecticut State University with a Bachelor’s degree in Construction Management. I started my career in the field, working on the labor side of site work and commercial remodeling, which gave me a strong, ground-up understanding of construction.
Over the past seven years, I’ve worked on a range of commercial projects including McDonald’s builds, sports complexes, ground-up carwash developments, and a new building project with Middlesex Hospital. I’ve operated a wide range of machinery and stayed closely connected to the field as my career has grown.
I’ve since moved into project management, superintendent, and office roles, where I’ve spent the last three years overseeing projects, coordinating teams, and keeping jobs on track. I’m also involved in pre-construction—bidding work, performing takeoffs, and building 3D models in SketchUp to keep owners, subcontractors, and teams aligned from the start.
To date, I’ve played a major role in over $16 million in projects, including six full ground-up builds. That experience allows me to bridge the gap between field and office, anticipate challenges early, and keep projects moving efficiently.
At 26, I’m focused on helping small contracting companies work smarter. I aim to reduce time and hassle through interactive tools that improve clarity and coordination—not replace the work, but support it in a way that actually makes a difference.
