Dru Mobley is best known publicly as Dru Ann Mobley, the mother of actor Armie Hammer and the former wife of businessman Michael Armand Hammer. Her name has attracted increasing interest because of her connection to the prominent Hammer family, her work in Christian ministry, her charitable activities, and her efforts to help women and children facing difficult circumstances. Although she is often introduced simply as “Armie Hammer’s mother,” her own life includes business, faith, philanthropy, writing, and community work.
Dru Mobley’s story is particularly interesting because it combines an Oklahoma upbringing with life inside a wealthy and historically prominent American family. She married Michael Hammer in 1985, raised two sons, Armie and Viktor, and eventually experienced a divorce after 27 years of marriage. In later years, she became increasingly involved in ministry and charitable work, including efforts focused on women affected by divorce and abuse. The Museum of the Bible describes her as the CEO and founder of Hammeredheart.org and notes her work with the Los Angeles Dream Center and Childhelp.
Who Is Dru Mobley?
Dru Mobley is commonly identified by her full name, Dru Ann Mobley, and is also known publicly as Dru Hammer. She became widely recognizable because of her family connections, particularly her son Armie Hammer, who established a career as a Hollywood actor. IMDb identifies Dru Ann Mobley as Armie Hammer’s mother and Michael Armand Hammer as his father.
However, describing Dru only as Armie Hammer’s mother leaves out much of her own public work. She has been involved in Christian ministry, women’s discipleship, charitable activities, business, and Bible teaching. The Museum of the Bible says she spent nine years working with the Los Angeles Dream Center, where her ministry included women’s discipleship and work involving victims of human trafficking. It also identifies her as the founder and CEO of Hammeredheart.org, an organization intended to help women and children who have experienced difficult circumstances involving divorce and abuse.
Dru Mobley’s Early Life and Oklahoma Background
Dru Ann Mobley was raised in Tulsa, Oklahoma, where her early family environment played an important role in shaping her values. Accounts of her life describe a strong Christian upbringing and an emphasis on faith, family, responsibility, and service. Her father, Douglas Mobley, is frequently mentioned in accounts of her life as an important influence, particularly because of his Christian ministry and commitment to helping others.
Her Oklahoma background remained important even after her life changed dramatically through marriage and relocation. In 2017, Dru returned to Oklahoma as a featured speaker at a Pi Beta Phi alumnae event, where she discussed faith, life, forgiveness, and the future. The event coverage noted that she had been president of the Oklahoma State University Pi Beta Phi chapter during her student years and later worked in Tulsa.
Dru Mobley’s Education and Meeting Michael Hammer
Dru attended Oklahoma State University, where she became involved in campus life and the Pi Beta Phi organization. Her university years were an important stage in her development before she entered the nationally prominent Hammer family. Sources describing her life connect her education with her later professional and personal journey, although detailed information about every aspect of her early career is not consistently documented by primary sources.
After graduating, Dru eventually met Michael Armand Hammer, the businessman and heir connected to the Hammer family. According to an Oklahoma newspaper account, she met her future husband while traveling, and the two subsequently built a life together in Los Angeles. The Museum of the Bible confirms that Dru married Michael Hammer in 1985.
Dru Mobley and Michael Armand Hammer’s Marriage
Dru Mobley and Michael Armand Hammer married in 1985. Michael was part of the famous Hammer family and the grandson of industrialist Armand Hammer, whose business career and philanthropic activities made the Hammer name internationally recognized. Their marriage placed Dru within a wealthy and influential family, but she continued to develop interests and responsibilities of her own.
The couple spent many years together and raised two sons, Armie Hammer and Viktor Hammer. Their marriage ultimately lasted 27 years before ending in divorce. A 2017 report about Dru’s speaking engagement specifically described her as having gone through a 27-year marriage before divorcing Michael. Other biographical records place the divorce around 2012. Michael Hammer later died of cancer in November 2022 at the age of 67.
Dru Mobley as the Mother of Armie and Viktor Hammer
Dru Mobley and Michael Hammer have two sons, Armie Hammer and Viktor Hammer. The Museum of the Bible identifies Armie as an actor and Viktor as a financier. IMDb likewise lists Dru Ann Mobley and Michael Armand Hammer as Armie Hammer’s parents and Viktor Hammer as his younger brother.
Armie Hammer was born in Los Angeles in 1986 and eventually became known for films including The Social Network, The Lone Ranger, and Call Me by Your Name. His growing celebrity brought greater attention to his family, including his mother. Viktor, by contrast, has maintained a considerably lower public profile and is generally described as a financier. Dru has also become a grandmother through Armie’s children, Harper and Ford, whom the Museum of the Bible identifies as her grandchildren.
Dru Mobley’s Relationship With Armie Hammer’s Career
Armie Hammer’s decision to pursue acting was not initially the obvious path for someone from his family background. IMDb notes that his parents did not initially support his decision to become an actor because they preferred that he pursue business. That detail provides useful context for understanding Dru’s relationship with her son’s career: her concerns were reportedly connected to the uncertainty and values associated with Hollywood rather than a lack of belief in her son.
As Armie established himself professionally, his family became more publicly connected to his career. Dru eventually supported his work, and her public identity became increasingly associated with being Armie Hammer’s mother. Nevertheless, her own activities remained distinct from his acting career. Her work in Christian ministry and charitable organizations has continued to form an important part of her public profile.
Dru Mobley’s Faith and Ministry Work
Christian faith is one of the strongest themes in Dru Mobley’s public life. Her ministry work has included Bible teaching, women’s discipleship, and efforts to support people dealing with difficult life circumstances. The Museum of the Bible describes her as a Bible teacher and highlights her work at the Los Angeles Dream Center, where she spent nine years working in women’s discipleship and with victims of human trafficking.
Her message has frequently focused on hope, forgiveness, healing, and rebuilding life after hardship. During her 2017 Oklahoma speaking engagement, Dru discussed faith, life, forgiveness, and the future, explaining that a transformative experience during a trip to Jerusalem influenced her decision to pursue ministry more broadly. This part of her story helps explain why her later public work moved beyond family and business into religious outreach and personal encouragement.
Dru Mobley’s Charity and Hammered Heart Foundation
Dru Mobley’s charitable work is another major part of her public identity. The Museum of the Bible identifies her as the founder and CEO of Hammeredheart.org, an organization focused on helping women and children who have experienced difficult situations involving divorce and abuse. Her involvement with the organization reflects the emphasis she places on rebuilding lives and providing hope after personal hardship.
She has also served on the National Board for Childhelp, a nonprofit organization dedicated to helping victims of child abuse. Her association with the Los Angeles Dream Center further expanded her work with vulnerable communities. These activities demonstrate that her public career cannot be reduced to her connection with the Hammer family because much of her later work has centered on service, ministry, and helping people facing serious personal challenges.
Dru Mobley as an Author and Public Speaker
Dru Mobley has also developed a public voice through writing and speaking. Her memoir, Hammered, is closely connected to the themes that appear throughout her public work, including family, faith, difficult life transitions, forgiveness, and personal recovery. The book has helped make her experiences accessible to audiences who may know her primarily because of her famous family.
Her speaking engagements have similarly focused on practical spiritual encouragement rather than celebrity culture. Her Oklahoma appearance, for example, centered on faith, life, forgiveness, and the future. This public role has allowed Dru to speak to audiences about personal experiences while connecting those experiences to her Christian beliefs and ministry. Her later projects have also included Bible-focused digital initiatives, with the Museum of the Bible noting plans for gethope.AI and the 365journey program.
Dru Mobley’s Life After Divorce
The end of Dru Mobley’s marriage to Michael Hammer became an important turning point in her life. After 27 years of marriage, the couple divorced, and Dru subsequently placed greater emphasis on ministry, faith, and helping others who were experiencing difficult transitions. Her public message suggests that divorce became not only a personal challenge but also part of the experience that influenced her later work with women.
Rather than allowing the end of her marriage to define her entire identity, Dru developed a public role centered on encouragement and service. Her involvement with women’s discipleship, the Los Angeles Dream Center, and Hammered Heart reflects this direction. Her story is therefore often presented as one of rebuilding and finding a new purpose after a major personal transition.
Dru Mobley Today and Her Lasting Public Interest
Interest in Dru Mobley continues largely because several major areas of public interest intersect in her story. Searches for “Dru Mobley” and “Dru Ann Mobley” frequently lead people to questions about Armie Hammer’s mother, Michael Armand Hammer’s former wife, the Hammer family, her Christian faith, and her charitable work. Her connection to a famous Hollywood actor has naturally increased public curiosity, but her own ministry has given her an identity beyond her family.
At the same time, it is important to separate well-documented information from claims repeated by low-quality celebrity websites. Details about private family matters, exact financial figures, personal relationships, and other sensitive subjects are sometimes presented online without reliable sourcing. The strongest available sources support Dru’s identity as Armie Hammer’s mother, her marriage to Michael Hammer, her two children, her ministry background, and her charitable activities.
Conclusion
Dru Mobley, or Dru Ann Mobley, has lived a life that extends far beyond her connection to the Hammer family. Raised in Oklahoma and shaped by Christian faith, she attended Oklahoma State University before marrying Michael Armand Hammer in 1985. Together they had two sons, Armie Hammer and Viktor Hammer, and spent decades building a family life before divorcing after 27 years of marriage.
Her later work provides perhaps the clearest picture of the person she has become. Through Bible teaching, women’s discipleship, charitable work, public speaking, and Hammered Heart, Dru has focused much of her public life on faith, forgiveness, hope, and helping people overcome difficult circumstances. While many people first discover her through searches about Armie Hammer, Dru Mobley has established a public story of her own—one shaped by family, faith, service, and personal reinvention.
