From First Words to Finish Lines: Denisse and Matty’s Journey at Birch and Beyond

Four years ago, words were something Denisse Macareno hoped for but couldn’t yet hear from her son Matty who is on the autism spectrum. Now, the small conversations they share, once believed to be out of reach, are fueling every mile she runs for Birch Family Services in the New York City Half Marathon. 

Denisse enrolled Matty at Birch’s Springfield Gardens Education Center when he was three years old to help support his needs and give him the tools to succeed both in and out of the classroom. Now, seven-year-old Matty continues to grow and learn every day, reaching milestones that once felt distant.  

“He went from being nonverbal to communicating and being able to tell me what’s wrong,” Denisse said. “It’s a big change in him, and it’s wonderful. I’m very thankful for how much his school is willing to help and how communicative they are.” 

Watching her son’s progress inspired Denisse to find a meaningful way to thank his school, its staff, and the organization that has helped her family and thousands of others thrive. So, when she heard Birch was looking for runners to represent Team Birch in the 2026 New York City Half Marathon, she knew exactly how she wanted to give back. 

“It’s the least I can do for everything Birch has done for my son and family,” Denisse said. “It’s giving back to an organization that has done wonders for my son and the wonderful people that have seen Matty grow up.” 

Although Denisse admits she is not the most athletic, this will actually be her second time running the New York City Half Marathon, having run last year for a different organization. Though she is running for Team Birch, her participation has a much deeper meaning. For her, the run is about more than the miles or medals—it’s for Matty.  

“My son is not mentally able to be involved in sports and be a part of the team,” Denisse said. “So, I want to be able to do that for him, and I want my kids to be proud of me.” 

Behind every mile she runs is the gratitude she feels for the support her family has received. Denisse credits Birch with helping both her son and her family find confidence and hope for the future. 

“I was very worried about my child, as any parent worries for their child,” Denisse said. “With Birch, the tools that they have given me, and the fact that he’s progressed so much in just a couple of months, I have confidence that my boy is going to thrive in this world and he is going to be okay.” 

As race day draws closer, Denisse trains but isn’t focused on her time or pace. What matters most to her is the meaning behind each step and the example she hopes to set for her family. 

“When I cross that finish line, I just hope to make my children happy. I hope to give them a good story, and I hope they will be inspired,” Denisse said. “I hope other parents are inspired and help out.” 

Each time Denisse laces up her shoes, she finds herself thinking about the parents who are just starting where she once began, walking into Birch with questions and hope. To them, she has a simple message. 

“Your child is in good hands at Birch.”
