Teresa Nelson, ASLA, LEED AP BD+C, GRP

Teresa Nelson is a registered Landscape Architect and co-owner of Roof Top Sedums, LLC.  Prior to owning and operating her own business, Teresa accumulated 12 years of experience working at several multi-disciplinary firms in Illinois and Michigan.  As a Landscape Architect, she's been a team member on a wide range of both public and private sector projects, including park design, streetscapes, commercial and residential developments, and most recently, green roof designs.  In 2006, a green roof design in Michigan gave her the opportunity to work with LiveRoof, LLC, and the rest, as they say, is history.  Ultimately, her interaction with LiveRoof® led to the opportunity to become a grower and promoter of green roof projects for LiveRoof LLC regionally.  Since 2007, she has been working with her family's operation in Davenport, Iowa to develop Roof Top Sedums into a regional grower for the LiveRoof® Hybrid Green Roof System, servicing all of Iowa, most of Missouri, eastern Kansas, eastern Nebraska, and western Illinois.  Currently, she spends most of her time sharing what she's learned about green roof design, taking into account plant health, green roof longevity, and overall sustainability of the site.

Roxanne Nagel, Horticulturist, GRP

Roxanne Nagel is a horticulturist and co-owner of Roof Top Sedums, LLC.  Since 2007, she has played a significant role in the development of the company’s success as regional promoter and grower for the LiveRoof® Hybrid Green Roof System.  As much as she would like to get her hands into the dirt more often, her daily responsibilities are related more to the administrative functions of the business.

Prior to becoming a co-owner of Roof Top Sedums, LLC, she obtained a BS in Horticulture from Iowa State University.  As a college intern and during her post-graduation career, she held several horticulture positions at sites such as Mid-American Growers, ISU Reiman Gardens, EPCOT Center at Walt Disney World, Pioneer Hybrid, HM Buckley and Sons, Inc., and The Growing Concern.  Just prior to her journey with Roof Top Sedums, LLC, she owned and managed a family greenhouse operation that included bedding plants, mixed containers, cut flowers, and fruit and vegetable production.  As Roof Top Sedums, LLC continues to grow she has stepped aside from the family greenhouse operation to focus her efforts solely on growing Roof Top Sedums, LLC even more!
