[Meridian, Idaho] – January 20, 2026 — Sorren, a Top 50 national tax, accounting, and advisory firm, has announced the appointment of Josh Tyree as Chief Executive Officer, effective January 20, 2026. Tyree previously served as President of the firm and steps into the CEO role following a planned leadership transition.
The appointment reflects a long-established succession plan designed to support Sorren’s growth and integration as a national firm. Michael O’Donnell, who has served as CEO during Sorren’s initial formation and integration period, will transition to Executive Chairman, where he will continue to provide strategic guidance and leadership counsel.
“This transition was planned from the beginning,” said O’Donnell. “Josh has demonstrated exceptional leadership, operational discipline, and a clear vision for the firm. The progress Sorren has made over the past two years exceeded expectations, and Josh is well prepared to lead the firm into its next phase.”
As President, Tyree focused on partner alignment and firm integration, helping bring together multiple legacy firms into a cohesive national organization. In his role as CEO, he will continue to support partner success while placing greater emphasis on strategic direction, innovation, and the development of new service offerings.
“This role is about building on what we’ve already established,” said Tyree. “We’ve made tremendous progress as a firm: aligning our partners, strengthening our culture, and creating a strong foundation for growth. As CEO, my focus is on ensuring we continue to move forward with clarity, purpose, and care for our people and our clients.”
Sorren has advanced its integration and operational milestones ahead of its original timeline, reinforcing its position as an established, nationally connected firm with deep local roots. Tyree’s appointment underscores the firm’s commitment to stable leadership, thoughtful governance, and long-term value creation.
