The Amache Alliance is overseen by its Board of Directors led by Mitch Homma and Kirsten Leong, both descendants of Amache incarcerees.   The all-volunteer Board and Special Advisors includes descendants, scholars, and other local and national professionals from across the country.

Mitch Homma is a sansei and works as an aerospace engineer.  He is an Amache descendant who had three generations of family incarcerated at the WWII Granada Relocation Center in Colorado.  He volunteers with the Amache Historical Society II (AHS II), coordinates their newsletter, and supports several Amache preservation projects.  As Vice President of the Board of Managers for the American Baptist Historical Society (ABHS), he has worked on several history related educational and preservation projects.  Volunteer ABHS executive committee responsibilities include strategic plan development and professional standards guidelines for intellectual property protection.


Vice President, Dr. Kirsten Leong

Kirsten Leong is a Yonsei and Amache descendant of the Sameshima and Omori families.  She is one of the founding members of the Amache Historical Society II, updates the website, and distributes newsletters.

Secretary,  Dana Ogo Shew

Dana Ogo Shew serves as a Staff Archaeologist, Oral Historian, and Interpretive Specialist at the Anthropological Studies Center at Sonoma State University in California.  She specializes in projects that research, preserve, and share stories about the Japanese American experience, especially those related to WWII Japanese American incarceration. She earned a MA in archaeology from the University of Denver where she researched the lives of women at Amache.  Dana has family ties to Topaz War Relocation Center, where she has done informal archaeological surveys and will be conducting formal archaeological investigations this summer.  She is working on updating the Amache Interpretive Plan and supports AHS II on many projects.


Treasurer, Stephanie Stone

Stephanie Stone is a retired software/systems engineer.  As a software developer, project lead, database architect, and systems interface manager, her projects led to national intelligence advancements.  Her technology and finance skills have been utilized on several non-profit projects.  She grew up in the southeast and was not taught anything about the WWII Japanese American experience.  She has been involved with the Amache community since 2008 and visited Japan multiple times supporting research. 


Compliance Officer, Dr. April Kamp-Whittaker

Her publications include works on the archaeology of institutional confinement, the archaeology of childhood, and historic urbanism.
