About Us

My name is Mary Ann Heinz, and I am a 1988 graduate of St. Louis Community College Occupational Therapy Assistant Program. I have worked as a COTA/L in pediatrics in both preschool and elementary school settings for most of my career. My husband Greg has a background in Mechanics and Electronics and works in the Engineering field as a Designer. This blending of education and experience gave birth to HandiThings®™ in 1998.

While working for a large school district I found that the majority of the students with whom I worked had handwriting difficulties. A unique tool was needed that would facilitate the appropriate pencil grasp, allowing the student to focus on the basics of letter formation, size, line, and space adherence. It was from this need that my husband and I conceived and developed our first product; the HandiWriter®™. We applied for, and were granted a US patent in November of 1999. All of our subsequent products have been developed from the direct needs encountered in the educational and therapeutic environment.

Since it's inception, HandiThings® has operated as a cottage industry. While we have grown and expanded our product line and customer base over the past 12 years, we prefer to keep production in the hands of a dedicated team of experienced seamstresses and assemblers who work from their homes producing products that meet our high quality standards. By having frequent and direct contact with our skilled workers, we can maintain strict quality control and monitoring for product consistency and improvement.
