Diane Lindsay Tower has followed in the footsteps of her parents, Dr. Richard and Betty Lindsay, to offer tremendous support to Merrimack Valley and Ironstone Farm specifically. For two generations, members of the Lindsay and Tower families have offered lifetimes of service to local families and their beloved pets through the caring operation of Andover Animal Hospital. With Diane joining Challenge Unlimited's nonprofit board, she continues a tradition of supporting both equines and humans at Ironstone.

During these past 20 months of COVID alone, Diane provided the most significant contribution toward completely redoing Ironstone's main horse paddock for the first time in decades. This has created a drier, safer and more modern space for volunteers, staff and the majority of the nonprofit's horses. Diane also paid for other vital needs during the height of the pandemic, including months of hay to feed the horses that help improve lives every day. 

This continued the tradition of care for Ironstone started by her father, who introduced Diane to Ironstone when she was a little girl. Dr. Lindsay was the veterinarian for Ironstone for many years and contributed substantially to pay off its debt and make it sustainable. When government and insurance programs stopped paying for children 3 and older to receive therapy, he suggested the "Sponsor a Child" idea that has helped hundreds of children continue their life-changing rides, regardless of their families' ability to pay. Diane, her brother David, and the Lindsay and Tower families have generously started an endowment to support Sponsor a Child for the long-term.
