Who We Are

Our Company

a bove the Sill, a Woman-Owned, Small Business was founded in 2004 by Joan Serio.  She and her husband took their more than 40 combined years’ experience in the window treatments world and started on their own.  The company’s original focus was on residential window treatments.  As the organization grew, they knew that servicing the healthcare and commercial industries was important. Since then, Above the Sill has grown to have serviced Hospitals, Nursing Homes, Commercial Buildings, Government Facilities, Universities, Schools, and more across not only Florida but the entire United States as well.  As we continue to grow, we continue to expand our customer base by partnering with Architects, General Contractors, Interior Designers, and End-Users too.  Please don’t hesitate to reach out and contact us today to discuss your upcoming construction or renovation project!
