David A. Heim, the founder of The Wheelchair Recycler and Wheelchair Conversions, died peacefully, June 20, 2017, with his family by his side at Rose Monehan Hospice in Worcester. Born in Waltham, he was the son of Frederick K. and Rachel (Wheelock) Heim of Marlborough. In 1998, David recognized the need of the mobility impaired for wheelchairs that were affordable and available in a timely manner. He founded The Wheelchair Recycler, Inc. in Marlborough, using his background as an accomplished machinist. As president, he worked alongside his son Joe, and his business partner and good friend Pedro Trovo. Although nationally recognized for his efforts, David’s dream was to help as many people as possible by recycling, refurbishing and reclaiming used electric wheelchairs, scooters and other medical equipment.
