Don Luman-ag is a National Book Development Board-registered author and writer in the Philippines. He has self-published two poetry books which are both available at Amazon.com; namely, INFINITY AND BEYOND: A Collection of 100 Selected Poems About This Journey Called Life by Don Luman-ag and TO MY BEST FRIEND: An Illustrated Poem under the pen name Don McKinley. He has also taken part in several international book anthologies and has written a number of forewords, introductions, blurbs and reviews for his fellow authors around the globe.

Don is the Honorary Founder and former President-CEO of McKinley Publishing Hub based in Kentucky, USA, his brainchild which he named after the street where he lives. He was primarily responsible for the publishing of some notable authors' first book - being hands-on during the entire book development process from cover design, book interior layout, editing, proofreading and promotion. His handiworks have been cited and recognized by reputable international literary groups and well-respected figures in the industry.

As a published author himself, it has been one of his personal advocacies to discover and help less privileged but exceptionally talented aspiring authors finally get the recognition and honor they deserve, by helping them realize their dreams of becoming certified published authors themselves.
