I’d like to express my sincere appreciation for the outstanding support provided by Ms. Iris Terashima during her visit with the 611th Air Support Group on 27-21 Aug 09 at Elmendorf AFB, Alaska.

Ms. Terashima’s support enabled my staff to address findings of the recent independent audit of our Environmental Management System (EMS).  She corrected many findings of the audit and provided options for corrective actions to address other findings.  Her enthusiastic support was instrumental in my decision to declare full EMS implementation a full 4 months earlier than anticipated.

Please pass along my appreciation to Ms. Terashima for a job well done!”
