Who, living or dead, would you like to eat dinner with the most? And why?
I would love to have dinner with an 18-year-old me. All my memories shaped me into who I am today. I am thankful for my experiences, but I certainly could have listened to my parents more. With that said, I would let my 18-year-old self-know that all that nagging and long lecturing is guidance that I do not want to miss. As I look back, it truly could have helped me. I would tell the 18-year-old me to build strong relationships and show emotions with my whole heart. Laugh until you cry and cry until you laugh. Love with every part of you. When you are happy, jump for joy. When you are angry, scream at the top of your lungs. Do not hold on to ill feelings, let it go. People do not mean to be hurtful; it is simply a reflection of their suffering. Exercise, eat well, and take care of your body… your 40-year-old self will thank you later. Look out for yourself and surround yourself with people you trust. Live, love, and laugh uncontrollably.
How did you get into construction?
At the age of 14, I had the most amazing Architectural Drafting and Design teacher, Mr. Dietz. That is where my love for all things in design began. Upon graduating high school, I decided to attend Architectural school which is what brought me to Boston. I began my post-secondary education at Wentworth Institute of Technology and then transferred to Massachusetts College of Art to finalize my studies. After a decade in Boston and a few experiences in the architectural and design field, I ended up making a slight change to construction by taking a position at Commodore.
Who or what inspires you?
I am inspired by my children. They are an immense part of who I am today. They keep my head up. When it tilts just thinking of them lifts me up. Three completely different personalities continue to teach me what life is all about. And the reason Mimosas are not just for Sunday brunch…
What is one thing on your bucket list and will you accomplish it?
I have always wanted to go to Greece. I love its history, culture, and beautiful architecture. It was a childhood wish of mine to go to Greece with my father after graduating from college. My father passed away before we could make this wish come through. My daughter and I have plans to visit Greece for her 18th birthday. We hope to expand the trip and visit other neighboring countries such as Italy, France, and Spain.
