The ultimate older sister, Lauren has been looking out for the bride for 31 years. Some might say she was bullied into letting Keri onto the school bus first, but pay that no mind. She always asked where the bathroom was when the bride wouldn't, always had an answer when the bride asked "is this weird?", and even got the bride her first 3 jobs.

A true partner in crime, Mike is the Patrick to Brian's SpongeBob. They bicker like an old married couple, but laugh it off like the old guys, Statler and Waldorf, from The Muppets.

It started out an unlikely friendship, Keri was a goody-two-shoes and Megan was too-cool-for-school. Megan was the OG bad influence friend, yet somehow she was mom-approved and the shenanigans abounded. Wanna hear about the first time the bride got drunk? Ask Megan. 17 years later, peanut butter and fluff are still the best combination.

As the older brother, Steven paved the way for many of Brian's interests and always helped him out of various jams. From shaping Brian's taste in music, to taking the blame in sibling spouts, chauffeuring Brian to countless concerts, and fostering Brian's love for hockey.

As the only two freshmen in a senior-level computer science class, the bride approached Gabby desperately hoping for a homework buddy. Instead, she got a lifelong friend and hype-woman who always reminds the bride that both the big and little things in life are worth celebrating (and getting dressed up for).

Ben and Brian met in college while working at their school's newspaper thanks to Brian's need to copy Ben's homework. From ridiculous nights out in Manhattan to kitchen dance parties at Ben and Elise's home in Tennessee — their bond and perpetual Yankees vs Mets rivalry continue to this day.

When Hannah decides you're going to be her friend, you're in for life. Even though the bride didn't live in Seattle long, that time was jam-packed with adventures like getting lost in search of a waterfall and hiking down a mountain in the dark. One of the most kind-hearted people out there, Hannah is the kind of friend who will let you drive her car from Washington to Montana and doesn't even bat an eye when you tell her the windshield cracked.

Rich and Brian went to high school together, but their friendship really took off when Rich offered to let Brian and Paul sleep on his Boston College dorm room floor while attending a video game convention. That one year turned into ten consecutive years of visiting Rich and his now wife, Mary, in Boston. Brian would eventually meet Keri through Rich and Mary who also live in Atlanta now, so really they're to blame for all this.

When the bride met Brittany at a work training she wasn't expecting to make a friend for life, but as soon as she learned Brittany was a genuine reality-TV junkie, she knew it was meant to be. Their friendship blossomed over a shared love of The Challenge, travel, red wine, and rose-gold decor (okay that last one might be a universal millennial thing...). Brittany is the kind of friend who willingly gets lost in a corn maze so you can finish your long-winded story about how much you like this guy you met at a wedding who lives in California.

Paul and Brian's friendship dates all the way back to around 2004 over a mutual love for Halo 2. These two have spent an immeasurable amount of time together and definitely share that sibling relationship. They spent countless nights at Paul's house playing video games until the sun was up, roomed together at the University at Buffalo, and even share matching tattoos!

Brian and Alex go way back to Brinckerhoff Elementary, but only became the best of friends when they - rather randomly - found themselves both moving to Atlanta. After many island vibes, Reality TV debriefs, and puppy playdates, Alex and his wife Ashley became not just Brian's friends, but Keri's too. Brian and Keri knew that by having Alex as their officiant they would have a ceremony filled with Alex's wit and Ashley's class.
