As Meredith's younger sister, Bess has spent years professionally humbling her. As Meredith's best friend, she’s spent just as long being the person the bride couldn’t live without.

Emma and Meredith met in college, sitting on the steps of their dorm hall. Flash forward 10 years, and they're still big fans of sitting on the floor and yapping.

Anna and Meredith met because Anna is Bess's best friend, but after 12 years, Anna is considered the third Lehman sister — honorary title, lifelong membership guaranteed.

Lauren has known Meredith since high school, where they played volleyball and perfected the fine art of screaming at each other over a net. She’s witnessed the bride at her absolute worst and somehow thought, “Yes, I’ll keep her.” She is also an honorary Lehman sister.

Mackenzie and Meredith met because their husbands were in the same fraternity, so it was basically fate. They bonded over books and their shared love of fictional men who set wildly unrealistic standards. She’s the bride’s favorite person to read with, spiral with, and enable every new fictional obsession.

Paige and Meredith are another friendship success story stemming from having ADG husbands. Meredith broke her toe at Paige's wedding, so fingers crossed Paige comes out of Meredith's wedding in one piece.

Courtney and Meredith met through Courtney’s fiancé, Kevin, who was Matt’s roommate. On their first hangout, Kevin somehow gave Meredith a black eye with a volleyball during giant pong (true story). Courtney and Meredith have been besties ever since.

Katelyn and Meredith are coworkers and partners in navigating countless “learning experiences” at work. Somehow surviving it all together turned into a friendship that’s way too fun to be professional.

Matt and Matt met in their fraternity, where lifelong brotherhood was forged—despite Bergmann's devotion to the Dallas Cowboys. He’s the best man today because he’s proven he can survive both football heartbreaks and wedding planning with equal skill.

Kevin, the groom’s college friend (and the one who gave Meredith a black eye on their very first hangout—true story), has been navigating friendship, chaos, and accidental injuries ever since. He’s ready to support the groom ... and is fully insured this time.

Cody and Matt met through their fraternity. They bonded over sarcasm, bourbon, and navigating the kind of fraternity “adventures” that test your patience and your liver. Their friendship stuck, and he’s proudly standing by the groom today.

Austin and Matt met through their fraternity (see a pattern?), and their friendship has survived golf, chaos, and a pool basketball game that left Austin with a loose tooth—because some friendships come with a little dental risk. He’s standing by the groom’s side today… despite no extra dental coverage.

Tyler and Matt met in high school, and over the years they’ve become like brothers—so close that Tyler could walk into Matt’s houseand raid the fridge. In exchange, Matt could be the unofficial third wheel for Tyler and his girlfriend (now wife). Even though they live miles apart, they still act like brothers whenever they’re together.

Vince and Matt were college roommates, which means Vince knows just how grumpy Matt gets if he doesn't have his morning orange juice. Their friendship has spanned countless St. Louis Blues games, concerts, and multiple moves. Vince is Matt and Meredith's unofficial mover — a title they know he is honored to hold.

Connor and Matt have been friends since high school, and their friendship has only grown—they now tackle trivia nights together (mostly guessing, sometimes arguing, always laughing), and Matt even stood by Connor’s side in his wedding.

Kaleb and Matt met in high school and bonded at church. They used to stay up all night playing board games, and Kaleb even introduced Matt to Connor—one of his best moves ever. Their friendship has been going strong ever since.
