Logan's Story

2004

Born with half a heart

Logan was born with hypoplastic left heart syndrome (HLHS), a rare congenital heart defect where the left side of the heart never fully develops, so the right side does the work of both. Doctors said he wouldn't survive birth.

Childhood

12+ surgeries

Including three open-heart surgeries, and a pacemaker that keeps his heart in rhythm.

Age 7

He found the piano

He started on his mom's keyboard one Christmas. Music became the place that felt safe, familiar, and his. Fifteen years of classical piano followed, including Denver School of the Arts.

2006–2019

A wish, and a studio

Named the American Heart Association's Heart Victor as a toddler, he spent 10+ years giving back. At 11, Make-A-Wish gave him home recording studio equipment. That's where he started producing and mixing.

2015–2022

The big stages

As a SeriousFun camper he performed at benefit galas at Lincoln Center, the Dolby Theatre, London's Roundhouse, and Cipriani, alongside Tom Hanks, Meryl Streep, and George Clooney. 10,000+ people heard him play live.

Mission years

The Rapping Missionary

On supplemental oxygen since December 2022, he served a mission and wrote, produced, and filmed music videos that reached millions online, with coverage from The New York Times to Church News.

September 2025

A stroke, and a comeback

He survived a stroke and kept going. Today his exercise capacity is less than half that of a healthy person his age, so he works smart and paces himself, and the studio is where he shines. He's not yet on a transplant list and stays in regular care with his doctors.

Today

Lifting up other artists

Now in the San Francisco Bay Area, close to his medical care, Logan produces, mixes, and masters for other artists, so their songs communicate clearly and connect deeply.
