Twins Go Head-to-Head in NCAA Division III Women's Lacrosse Final Four

May 22, 2025

Amy Dion would go upstairs and put twin sisters Ainsley and Kelcey down in their separate cribs for naps. When she went back downstairs, a pair of noises would emanate on the baby monitor.

First, there’d be the giggling. Then a loud “thump” that repeated over and over. She would go back upstairs to check on the girls and crack open the door, only the find that the two had taken their stuffed animals and lined them up on the sides of their cribs. One would jump over into the other’s crib and land on the plush toys. Then, they would push each other back and forth over the cribs. Eventually, the game would tire them out, and they would fall asleep in the same crib together.

Every night, this happened. Even when their mom tried to separate them, Ainsley and Kelcey Dion always wound up together.

Now seniors in college, the sisters chose to play lacrosse at separate schools: Kelcey plays for Middlebury, and Ainsley plays for Colby. Even though they decided to go their own ways, the sisters — both of whom major in economics — find themselves together again, competing against each other for the final time Friday in the NCAA Division III women’s lacrosse semifinals in Salem, Virginia.

“We’re both supposed to graduate on Sunday,” Kelcey Dion said. “My family is coming down for the Friday game, and then the loser goes home and graduates on Sunday, which is also wild. My parents are trying to deal with whatever happens.”

Kelcey started playing lacrosse in first grade after watching their older sister, Taylor, play. Ainsley initially didn’t want to, but she joined Kelcey in second grade. From then until their senior year of high school at North Andover in Massachusetts, they were teammates.

They played lacrosse and soccer and ran track. Their first taste of competing against each other came in track, where they ran the same events. Ainsley said one week, one of them would finish first and the other would finish second, only for them to swap places at the next meet.

In lacrosse, their playing styles complemented each other. Ainsley would take the draws and push them forward to Kelcey, who would win them in the air. Occasionally, at practice, however, the sisters would be pitted against each other in ground ball drills, and the whole team would make a big deal out of the moment.

“Oh my gosh, it’s sister versus sister,” Ainsley remembered them saying. “It’s Dion versus Dion.”

During the recruiting process, the sisters wanted to take the opportunity to “be our own people” and go down their own, individual journey. Even when they looked at the same school — Middlebury and Colby were potential destinations for both — they told the coaches they wanted to be recruited individually, having their own meetings in their offices without the other sister.

Ainsley Dion remembered the first visit to Colby was snowy and cold, but when she met head coach Karen Henning, she saw how supportive she was and the “fierce love” she has for her players. She saw the success she could have athletically and academically.

Kelcey Dion needed slightly more convincing to play at Middlebury. Division I was her dream, and she was close to committing to Davidson at the Division 1 level. One of her coaches at Laxachusetts was friends with an assistant at Middlebury. Knowing Kelcey’s desire for a mixture of strong academics and athletics, the coach convinced her to give it another look. After visiting campus and speaking with players on the team, she was sold.

The first meeting between the sisters in NESCAC play didn’t take place until April. Middlebury beat Colby 13-5. Ainsley Dion scored one goal. Kelcey Dion tallied one goal and two assists.

“Seeing her in a different uniform, going against her, emotions were crazy,” Kelcey Dion said. “I have always been her biggest supporter, and she’s always been my biggest supporter. Internally, I’m like, ‘Go, Ainsley.’ I want her to play so well and do well. But at the same time, I was like, ‘Wait, no, I love my team, and I’m too competitive to let her win.’”

Being NESCAC rivals didn’t stop the sisters from supporting each other. When they came home from school in the summer, they trained together at their high school field, setting up cones and running through drills for two or three hours at a time.

Through phone calls, visiting each other at school and even studying abroad, they also forged friendships with each other’s teammates. They studied in separate programs at the same time in Madrid while Colby’s Julia Jardina studied in Sevilla. The three travelled to Italy together one weekend, and they met up with Colby’s Kat Munter — who was studying in France — at Oktoberfest.

Those relationships don’t stop during their games, either.

“It’s always so fun to visit her because I know she loves them, and they love her, and they’re awesome people,” Kelcey Dion said. “It’s crazy when we match up against Colby because every other second I’m on the field, it’s, ‘Hey! How are you?’”

“Madison Paylor is great. She’s so funny,” added Ainsley Dion. “She’ll chirp me a little bit and joke around with me. It’s basically like having a sister. She’s just as supportive.”

Both teams have enjoyed success since the Dions arrived on their respective campuses. Colby reached the NCAA quarterfinals in each of Ainsley’s first three seasons. Unfortunately for her, her season ended twice at the hands of Kelcey and Middlebury, who won three consecutive national championships and enjoyed a 67-game winning streak that stretched from 2022 to the NESCAC semifinals this spring.

Kelcey Dion joked that her sister was probably sick of saying congratulations to her. Ainsley Dion admitted that when Colby wasn’t playing Middlebury, she wanted them to extend their winning streak, but partially because her team wanted to be the one that broke it. She said this year, when the teams met in April, was the game she felt she competed with the most intensity.

“[Kelcey] went out in the first quarter and scored the first two quarter of the game,” Ainsley Dion said. “In my head, I was like, ‘That’s enough. I’m not having anymore of that.’ It fueled me. Knowing her, and having the person beating me down in that moment be someone I also love, I was like, ‘Great. I’m going to take it to her now.’”

Ainsley Dion scored twice, her second goal staking Colby to an 8-7 lead coming out of halftime. The Mules went into the fourth quarter ahead 10-9 before Middlebury scored the first three goals of the final stanza. Kelcey Dion’s third goal of the game gave the Panthers a lead they wouldn’t relinquish.

While her team has been eliminated from the NCAA tournament each of the past three years, Ainsley Dion has still traveled to Salem to support her sister — always the first to congratulate her.

Kelcey Dion is happy her sister and her teammates have gotten over the hump and reached the final four this year, but it doesn’t come without mixed emotions.

“I’ve ended her season twice. Am I thrilled about the idea of potentially ending her career? No, not at all,” she said. “I wish that was up to someone else, but I am just really excited she gets to go to Virginia. It’s bittersweet.”

The senior class at Colby has had a motto all season: “Do something we haven’t done before.” The Mules already have checked that off, earning the program’s first trip to the NCAA semifinals. Ainsley Dion said the team’s Instagram post that said FINAL FOUR BOUND in all caps gave her chills.

The Colby senior class has never beaten Middlebury, either. In fact, the Panthers are the only NESCAC team Ainsley Dion hasn’t defeated, and she said the team is motivated for Friday’s matchup.

She described the success Colby has had this season as “awesome,” and she said getting to play one more game against her sister on the biggest stage of college lacrosse was a special moment.

“I know no matter what happens Friday, giving her a hug post-game will feel amazing,” she said. “Everything we’ve been working for the past 22 years of our lives — training together in the summer, all of that — I’m looking forward to a win, but I’m looking forward to hanging out with her afterwards.”
