Flowers: Amy Epstein of Crimson & Clover Floral Design Inc. in Baltimore used succulent-based flowers in all of the bouquets, boutonnières and centerpieces.

"The flowers were phenomenal," says Kristin. "She used white flowers and dusty millers. She was really delightful."

Special touches: The couple's daughter participated in the wedding. She rode in a red fire wagon down the aisle with a sign that read "Here Comes Mommy" on the back before Kristin walked down the aisle.

During the cocktail hour, Williams surprised his bride with a serenade.

"We had Chris Jacobs, lead singer of the Bridge in Baltimore, play the cocktail set," William says. "I got onstage and sang 'In My Life' by the Beatles."

Music: The couple's friend Elliott Heller, also known as DJ Equal, from Manhattan played during the reception.

William and Kristin's first dance was to "I Found You" by Alabama Shakes.

"For the first song, we wanted to keep it fun and a little more lighthearted," says Kristin. "I danced with my dad to a Stevie Wonder song. Everyone danced the whole time. It was really fun."

Lifesaver: The couple hired Jenny Bartkus of JPB Designs in Columbia as their day-of-wedding coordinator a little less than two weeks before the wedding.

"I was panicking right before the wedding and needed to hire someone immediately," says Kristin. "We called her and said our wedding is in 12 days, and she was really phenomenal. She took care of everything."
