After living in Bloomington for years, Mark Hash applied for a job at Commercial Service. Two decades later, he is retiring from his career as Lead Installer. Mark describes Commercial Service as a big company with small company values like family, teamwork, and a good support system.

As a 20 year veteran of the company, Mark witnessed the company grow to what it is today. Mark takes pride in knowing Commercial Service never stopped valuing quality—what he considers a differentiating factor. "Do it right. Do it one time." Mark explained.

We are so grateful for Mark's time on our team and wish him a happy retirement!
