Ryan Sisak is a museum leader and an emergent military/aerospace historian. He currently serves as Medal of Honor & Veterans Liaison for The National Vietnam War Museum in Mineral Wells, Texas, and is to be inducted as a member of the Military Order of the World Wars (Dallas Chapter) in August 2025. 

Previously he served as Vice President, Board of Directors, & Historian for The National Vietnam War Museum, from 2024–2025. During that time he stood up a Medal of Honor Advisory Board with 4 (of the 61) living Medal of Honor Recipients and researched and wrote three exhibits on "The Draft," "The Gulf of Tonkin Incident," and "The Red Scare, Domino Theory, & McCarthyism." He also has 13 years of experience as a professional educator.

Mr. Sisak holds a Master of Arts in International Heritage Management (with Merit) from the University of Birmingham, UK, and his dissertation was subsequently published in the Yearbook of Transnational History, Volume Six (2023). The published work represents the first scholarly recognition of places in outer space from Apollo 8 and Apollo 11, around the Earth and the Moon, as heritage sites embedded within the astronauts' spatial stories.

Mr. Sisak's forthcoming book (with Anthem Press, UK) will be the first scholarly work to recognize the aerial battlefields from the Battle of Britain and the Combined Bomber Offensive (both from World War II) as historic battlefields embedded within surviving veterans' spatial stories.

Mr. Sisak resides in North Texas, with his wife and children.
