Zac and Mark became friends over a bizarrely long handshake in high school. Their status as best friends was secured over the following months and mutual appreciations of Linkin Park, Dragostea Din Tei, and other pop cultural artifacts that have not stood the test of time like their friendship.

Michele and Gia became friends in 1993, fittingly, alongside Whitney Houston’s “I Will Always Love You” securing it’s spot as the longest running #1 single of all time. Not unlike the seminal classic, their friendship boasts soaring highs, dramatic lows, and an appreciation for Kevin Costner. Michele is often referred to as “my person” by Gia.

Angie has always been more than just an older sister to Gia. From total opposites, to life-long friends, to a reluctant high-school chauffeur. As adults, their bond is stronger than it has ever been through a mutual love of family and Angie’s children; Connor, Caden, and Kinsley.

More than just a brother; also a close friend and co-best-man, Mark and Scott's relationship has grown past sibling rivalry into a valuable friendship as adults, despite all Vegas odds predicting the opposite.

Much like Christy, Leslie is the younger-er sister that Gia has always wanted, and she counts herself very lucky to have gotten them both. Leslie was the first member of Mark’s family to meet Gia, through a coerced encounter at the airport while Mark attempted to slink away unnoticed.

Kevin and Mark first met in second grade, at the age of 7, in 1995. This means that their friendship is roughly the same age as America Online. If there is anyone who has earned a spot in this wedding party, it's probably the best friend who outlived AOL CD's.

Christy is the sister of the groom, a role secondary on this day to a new one; the younger sister Gia has always wanted. She was there to capture the moment of their engagement and is well deserving of her position in this wedding party.

Chris and Mark have been friends for time immemorial, it seems, with Chris having forged the friendship out of lumber and nails. Mark introducing Gia to Chris and his wife Jenna was a landmark moment in the relationship of him admitting to himself and the world that he had found someone truly special.

Emalee and Gia’s friendship began in the workplace and was formed in part by a love of dogs, but in much larger part by the “did we just become best friends?” moment in Step Brothers. It is proof that, sometimes, good things come out of human resources.

Friend of roommate turned band member turned roommate turned friend turned lifelong friend, Jesse (aka Aaron, aka Dutch, aka A-Aron) and Mark briefly played in Trial By Fire, a moderately successful Journey cover band, together before living together for several years of lost productivity and lasting friendship.

Amanda and Gia began as neighbors, but became friends one fateful weekend when Amanda’s boyfriend Michael was leaving town and pawned Amanda off on her. From there, all it took was a mutual love of food, wine, and Yoga to work the food and wine off to forge a lasting friendship.

Josiah, best known for his work on Audio Adrenaline's 2015 release Love Was Stronger, fills out the role of groomsmen, newest close friend and confidant, and BGV's.
