Re: Update from Chris Reedy
To my friends and colleagues,
I wanted to personally share that I am currently undergoing a new course of medical treatment following recent consultations with my physicians at the Mayo Clinic. As many of you know, I have continued regular follow-up visits since my cancer diagnosis in 2019.
While this treatment may periodically require me to spend time away from the office, I will continue serving as Butler National’s Chief Executive Officer and remain actively engaged with our leadership team, employees, and Board of Directors throughout this process.
I am grateful for the support and encouragement I have received from the Board and from so many across the organization. Butler National has an outstanding leadership team, and I am confident in the continued momentum of our business and the opportunities ahead of us.
Thank you for your continued dedication, professionalism, and support. I look forward to continuing to work with all of you, whether in person or remotely, in the weeks and months ahead.
Best regards,
Chris
