Yrēfy LLC: Powering Arizona’s Jazz Movement
Yrēfy LLC, a mission-driven financial company led by a musician-CEO, Don Fenstermaker, has been a friend and supporter of Dr. William “Doc” Jones, Founder of the International Jazz Day AZ Foundation, for over 20 years.
In 2023, Yrēfy’s sponsorship helped elevate the Scottsdale Jazz Festival to new heights.
By 2024, strong support from the City of Scottsdale followed.
In 2025, the event was officially renamed the Yrēfy Scottsdale Jazz Festival in honor of this transformative partnership.
Now in 2026, Yrēfy LLC and the Foundation are planning the largest International Jazz Day celebration in Arizona’s history.
This partnership is built on shared purpose, a passion for music, and a belief in jazz as a tool for unity and cultural pride.
