Who Exactly Is Robert Cosby Sr.?
Robert Cosby Sr. serves as the bishop of Faith Temple Pentecostal Church in Salt Lake City, Utah. Mary is often called his co-pastor and equal. He keeps a lower profile than his wife on the show, but when he does appear, viewers see a steady, quiet presence.
Mary has publicly described him as her “rock.” After nearly 28 years of marriage, she still says they love each other and that he continues to cook for the family and offer calm support through every storm.
The Unusual Path That Brought Them Together
Their marriage began in a way few people expect. Robert was first married to Mary’s grandmother, Rosemary “Mama” Cosby, the founder of the church. Rosemary passed away in 1997. According to both Mary and Robert, Mama had made her wishes clear: she wanted her husband cared for by someone from the family after she was gone.
Mary has called the union “arranged” and said it was “kind of in my grandma’s will for us to marry.” They wed on September 28, 1998, in Chicago. Mary had recently divorced her first husband, Dana Harris. Importantly, Robert and Mary share no blood relation.
The decision caused family tension at the time, yet the couple has remained together for almost three decades.
Family Life and the Heartbreak They Faced in 2026
Mary and Robert welcomed their only child, Robert Cosby Jr., in the early 2000s. Junior appeared on several seasons of RHOSLC and was open about personal struggles. Tragically, he died on February 23, 2026, at age 23.
In the months that followed, Mary has spoken about how the loss brought her and Robert Sr. even closer. She has said the tragedy strengthened their bond and that she is grateful to navigate grief with him by her side. As of late 2026, Mary has returned to filming RHOSLC Season 7, noting that her son would want her to keep going.
Here’s a quick snapshot of the key details:

Why Their Relationship Continues to Fascinate Viewers
