Our Story

Where it all began …

Masterfully is a sister company to McMillan Study Guides, the creator of industry-leading study aids for Air Force enlisted men and women preparing for promotion exams.

In 1988, Staff Sergeant Chuck Emry had diligently studied the dense 500-page Air Force Professional Development Guide. He’d unsuccessfully attempted the exam for promotion to Technical Sergeant — twice.

Chuck wasn’t alone. Many Airmen took the notoriously difficult test multiple times before earning their promotions.

Chuck’s wife, Susan, stepped in to ensure that Chuck’s third attempt would be different.

She hand-wrote flashcards that empowered Chuck to pass the exam. In fact, he scored so well that the testing division grew suspicious. He had to retake the exam under intense scrutiny. He scored even higher.

Chuck’s peers wanted their own flashcards — and the McMillan Study Guides company was born. Success soon followed, as customers outscored their peers and word of mouth spread.

Susan and her sister, Gayle, co-founded McMillan Study Guides in 1988. Over the years, the flashcards evolved into books, software, audiobooks, and, ultimately, eLearning. McMillan quickly became a household name on US Air Force bases around the world.

The McMillan Study Guides company kept pace with progress in learning technology, ultimately creating a proprietary industry-leading multimedia eLearning platform for the study aids.

Masterfully launches Advisor Plus

Chuck and Susan’s son, Mike, leads Masterfully, a sister company to McMillan Study Guides. Founded in 2019, Masterfully presents its flagship product, Advisor Plus.
