Engelson, 42, tied the knot with nutritionist and heiress Tracey Kurland, who he's been dating since 2017.
Kurland, 31, and Engelson got engaged in June 2018, just two weeks after Duchess Meghan married Prince Harry at Windsor castle.
Engelson and Kurland married in Montecito, Calif., in a low-key ceremony that couldn't have been more different from the royal wedding, Entertainment Tonight reports.
Kurland wore a lace off-the-shoulder gown for the wedding, while Engelson wore a traditional black tux, according to photos obtained by The Daily Mail, and guests were treated to giant Jenga pieces with the couple's name and wedding date on them as favors.
Their rehearsal dinner was a much more dressed down affair.
"The aesthetic was so them. Trevor wore a pink suit and loafers, and Tracey looked stunning in a two-piece gown,"a source dished of the rehearsal dinner. "She wore her hair in loose waves and rocked an adorable black-and-white polka dot bow."
"They wanted the weekend to be laid back and comfortable, something where their personalities really could shine," the insider added. "They thought of every detail and were making sure their guests had the best time ... They were surrounded by all their favorite people and literally glowing."
Engelson married Markle in 2011 after dating for seven years in a setting similar to his wedding to Kurland.
The Sun reported that Markle and Engelson's September 2011 nuptials in Jamaica featured parties that included wheelbarrow race, drinking games and brunch, with their actual ceremony lasting just 15 minutes.
They divorced just two years later, with royal biographer Andrew Morton alleging that Markle ghosted him and sent her rings back by registered mail.
