The subject of numerous publications, Gegham's artistic merit has been recognized in the United States by various art publications, such as Art Business News. Several of his paintings have also shown digitally at Times Square as part of Art Takes Times Square 2012. In 2011, Artexpo New York recognized Gegham's The Last Light (2000) as Artwork of the Day on March 16. Gegham has also been the subject of numerous publications in his native country of Armenia prior to moving to the United States.

Gegham's oeuvre merges traditional and modern techniques and subjects in a seamless manner across various media and with a fresh perspective. Some of his most recent work will be showing at several juried exhibitions across the United States this fall.
