At Rumble Boxing’s Glen Cove studio, the lights drop low, the music lifts high, and for 45 minutes, something shifts. Your breath steadies. Your focus sharpens. The outside world quiets. And the confidence you didn’t realize was there begins to rise.

That’s exactly what owner Siobhan Miller Vitale hoped to create — a place where movement becomes meaning, where fitness builds resilience, and where every person learns they are stronger than they thought.

A Locust Valley native and Friends Academy grad (Class of 2010), Siobhan went on to Fairfield University before earning a Master’s in Entrepreneurship and Innovation from USC. She met her husband, Stephen, in 2019; they married in 2022 and are thrilled to be welcoming their first child in February 2026.

Her journey to Rumble is deeply personal. During a challenging period in her young adult life, Siobhan discovered boxing — and found more than a workout.

“Boxing became meditative for me. It helped me feel grounded and capable again.”

Rumble Boxing first opened in NYC in 2017, pioneering boxing in the luxury boutique fitness scene. Think: nightclub energy, trained coaches, and zero intimidation.

Siobhan immediately saw that Long Island needed a space like this — a studio where beginners feel welcome, community comes first, and confidence builds every round.

In 2021, she and Stephen signed on as owner-operators of Rumble Boxing Glen Cove, located in Village Square.

✔ Three Class Formats: Boxing + Strength • Boxing-Only • Strength-Only

“People walk out different than they walked in — lighter, stronger, clearer.”

Rumble Glen Cove regularly supports local charities, toy drives, fitness fundraisers, and awareness events — including ongoing partnerships benefiting children’s cancer, breast cancer, Alzheimer’s research, and more.
 Siobhan also returns to Friends Academy to speak on Women in Sports & Entrepreneurship.
