Ryan Sisak is a museum leader and an emergent military/aerospace historian. He currently serves as Curator for the Gallantry & Service Museum, on behalf of the Military Order of the World Wars (Dallas Chapter). Recently, he served as Medal of Honor & Veterans Liaison for the Irving Archives & Museum in Irving, Texas, as he curated the Service Beyond Duty special exhibition that highlighted Native American veterans and Native American Medal of Honor Recipients. In September of 2025 he was inducted as a Companion of the Military Order of the World Wars (MOWW, Dallas Chapter), and in June 2026 was awarded the MOWW Silver Patrick Henry Award for curatorial excellence in perpetuating the legacy and memory of the Dallas Chapter's veterans, through the Gallantry & Service Museum.

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 four 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 14 years of experience as a professional educator, which includes nearly a decade as a manager.

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.

Through his work founding and producing For Gallantry & Service, Mr. Sisak serves the heritage and historical missions of many veterans, Medal of Honor Recipients, their families, and organizations like MOWW and the Congressional Medal of Honor Society.

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