Executive Assistant

Hi, I'm Shannon!

Why I Love Supporting Families

What I love most about being an assistant is taking the everyday, time-consuming administrative tasks off someone's plate so they can focus on what matters most to them. Whether that's higher-level strategy at work, spending more quality time with family, or simply having a little more breathing room in their day, I find it rewarding to give people back their time. I enjoy getting to know the people I support, understanding their priorities & finding thoughtful ways to make their lives a little easier.

Professional Experience

I bring 14 years of combined experience in executive support, administration, sales & customer service, including 7 years in traditional administrative & executive assistant roles. Most recently, I've supported senior leaders in the financial services & technology industries, managing complex calendars, coordinating travel, juggling competing priorities & keeping busy schedules running smoothly.

My background in sales & customer service has shaped the way I work. I'm naturally personable, adaptable & comfortable building relationships with people from all walks of life.

Across all my roles, I've found that what I enjoy most is being someone others can rely on.

A Little About Me

I live in Brooklyn with my new husband & our cat, Peachtree. Outside of work, you'll usually find me playing soccer, cooking for friends & family, or planning our next trip. I love bringing people together, whether that's hosting friends, organizing a gathering, or finding an excuse to celebrate something. I'm all about the little details that make an experience feel special, & I'm happiest when I have something fun to plan!
