What unique strengths do you bring to your trade?
One of my biggest strengths is attention to detail. Even small mistakes can lead to big issues, so I take pride in doing clean, accurate work from the start. Another strength is my ability to adapt. Whether it’s switching between fabrication and installation, working in tight spaces or collaborating with other trades, I stay focused and efficient. Safety is always a priority for me as well. Lastly, I’m reliable. I show up on time, stay consistent and work well in a crew or independently.
What do you love to do when you are not at work?
Outside of work, I dedicate time to volunteering within my community and value the opportunity I have to connect with friends and family. These activities allow me to give back and maintain a strong support network.
Goals in the future — any ambitions or changes to your career, growth or education?
In the future, I aim to continue advancing my career by earning additional certifications to further develop my skills in the trade. I also have a personal goal of purchasing a home, which reflects my commitment to long-term stability and growth.
What surprised you about your trade?
What surprised me most about the sheet metal trade is how much precision and problem-solving it involves. It’s not just physical labor, there’s a lot of planning, math and attention to detail required to make sure everything fits and functions correctly. I was also surprised by the variety of work, from fabrication to installation, and how every project presents a new challenge.
What do you find frustrating about your job/trade?
One of the more frustrating aspects of the trade can be when projects are delayed due to factors outside of our control, like late material deliveries or changes in design plans. It can affect the workflow and timeline. However, I’ve learned to stay flexible and focused on what I can control, which helps keep the job moving forward.
What’s the coolest job you’ve worked on?
One of the coolest jobs I’ve worked on was my first jobsite in Dorchester. I also had the opportunity to do cornice work, which was both challenging and rewarding. What made it really memorable was being able to move around to different locations, including UMass Boston, the Cape and even parts of Rhode Island, and take in some amazing views. It gave me a real appreciation for the places this trade can take you.
What traits do you think a good sheet metal worker has?
A good sheet metal worker needs to have strong attention to detail and precision, since even small errors can affect the entire outcome of a project. Physical strength and stamina are important, but just as critical are problem-solving skills and the ability to read blueprints and follow technical instructions. Reliability, a strong work ethic and a commitment to safety are also key traits. And because we often work as part of a team, good communication and teamwork are essential to getting the job done right.
Why sheet metal?
I chose sheet metal because it was one of the few things that really interested me in high school. I’ve always been more of a hands-on learner than a book learner, and this trade gave me a chance to work with my hands while building real, useful skills. I was drawn to the variety in the work — fabrication, installation, welding — there’s always something new to learn and do. I also chose to join Local 17 because I want to build a solid future not just for myself, but for my family. My mom has worked two jobs for as long as I can remember, and my goal is to be able to support her when she retires so she doesn’t have to stress or worry anymore.
Tool you can’t live without?
The tool I can’t live without is my tape measure. It might seem simple, but accurate measuring is the foundation of everything we do in this trade.
And if I had to pick a second, my snips. They’re always in my pouch.
Best advice you got as an apprentice?
The best advice I received as an apprentice was to always show up on time and come prepared. Having a strong work ethic and being willing to put in the effort every day are crucial to success in this trade. Consistency and dedication go a long way in building your skills and reputation as well.
Best advice for an apprentice?
My best advice for an apprentice is to stay eager to learn and ask questions whenever you’re unsure. Be patient with yourself; skills take time to develop. Always show up on time, come prepared and be ready to work hard. Building a strong work ethic early on sets the foundation for a successful career.
What do you think about Tradeswomen Build Nations?
Tradeswomen Build Nations is more than a conference, it’s a powerful platform for visibility, sisterhood and empowerment. Whether someone is a first-year apprentice or a seasoned journeyperson, being among hundreds or thousands of tradeswomen brings encouragement and opportunity. For women in sheet metal or related trades, it’s an ideal place to connect, learn and reinforce why you belong in this profession.
Are you active in trade related activities such as career fairs, volunteer work, or SMART Army events? Can you elaborate on one you participated in?
Yes, I’m involved in trade-related volunteer work. One event that stands out was just before Easter, when I organized a small group to help deliver meals to senior citizens through a local food bank in Brockton. It was a meaningful experience to give back to the community, especially to those who may not have had support otherwise. Volunteering like this reflects the values of our trade: teamwork, service and making a positive impact beyond the job site.
