What is your guiding principle in life? Fail forward.
What led you to your career? I am a third-generation banker and thought I wanted to be a banker because I like numbers. But once I understood the impact I could have as a community banker in the many communities we serve, it was confirmation that this career is for me. To help someone with their next stage in life — a new home, starting a family or a starting a small business — is by far the most rewarding part of my job.
What would you like your life to look like in five or 10 years? I hope my family is happy and healthy and that I can continue to make a positive impact in the community through my work at BOS.
What do you wish your younger self had known when you started on this path? Don’t sweat the small stuff and the little things that cloud the bigger picture.
What has been your greatest professional achievement? Helping the bank implement an employee stock ownership plan.
What’s the song you sing in the shower? Currently, anything from the “Sing 2” soundtrack, thanks to my daughters.
