"Bill recently provided a Solaris Bootcamp for us at GDIT. The students in the class have been extremely satisfied and provided comments like "best training class I ever had". Bill also provided at no cost an extensive pre-class student assessment which allowed him to customize the class to our student's needs."

- C. L., Project Coordinator General Dynamics Information Technology

Recommendation / Reference:
"Bill Calkins wrote the book! I have a dog eared copy of Inside Solaris, and the System Admin Certification Training Guide. Both are invaluable to the Solaris community. Now imagine learning Unix in person with the author as your instructor. The book comes to life! I have had customers all over the world request Bill Calkins classes. Each and every time the results were the same; amazed, excited, and extremely positive. From consulting large multi-cultural/multi-organizational corporations to one on one mentoring, there is no one better equipped to bring order to the chaos. I highly recommend Bill Calkins for your next project."

He knows his stuff, worked with the students, if he didn't know something he researched and discussed the next day, etc. Our folks absolutely LOVED him (and they aren't easy to please). They are IT folks and are extremely tough on instructors. We are very pleased and wanted to say thank you again."
