Jennifer Rapp
Associate ASID, Principal Designer, Owner
Jenny has been a trusted interior designer in the greater St. Louis community for over 20 years. In 2011, she founded JCR Design Group, driven by her passion for residential design. Collaborating closely with homeowners and industry professionals, Jenny and her team bring each client’s vision to life with timeless style and functionality.
Originally from New England, Jenny earned her undergraduate degree from Brown University before starting her career in commercial banking in New York City and Chicago. While not creatively fulfilling, her business background provided valuable skills that continue to benefit her work today. Pursuing her true calling, Jenny transitioned to interior design, joining a prominent local firm where she gained exceptional experience and built enduring relationships with national and local showrooms, premier workrooms, and highly skilled craftsmen.
Jenny’s designs extend beyond St. Louis, with projects in Chicago, Boston, New York, and Florida. Her portfolio also includes commercial projects for businesses, schools, and churches.
Dedicated to her community, Jenny has served on the Board of Directors for The Woman’s Exchange of St. Louis since 1998 and joined the Board of Directors for the Frank Lloyd Wright House in Ebsworth Park in 2017. She and her husband reside in St. Louis, cherishing time with their two sons and their wonderful families.

Natalia Box
Senior Designer
Natalia’s career in interior design was foreshadowed by her teenage years, spent helping her parents with home renovations as she sacrificed social outings and revealed her natural talent and interest. Natalia went on to earn a Bachelor of Science in Interior Design from Missouri State University, complemented by credentials in Construction Management.
After graduation, Natalia gained valuable experience as an intern at a boutique design firm in Dallas before becoming a Design Assistant at a local showroom. A desire to be closer to family brought her back to Missouri, where she pursued commercial design, specializing in senior living and hospitality. Her true passion for residential design ultimately led her to join JCR Design Group in early 2019.
Now based in St. Louis, Natalia enjoys life with her husband, son, and two cherished dogs. On weekends, she can be found spending time with family and friends, browsing antique shops, tackling DIY projects, and exploring everything St. Louis has to offer.

Emily Koch
Senior Designer
Emily has had her sights set on interior design since the age of twelve, a love nurtured by her family’s shared interest in architecture and home design. As a child, she was often involved in her family’s personal design projects and spent many Sunday afternoons tagging along with her parents at open houses. This early exposure to design inspired her to pursue a degree in Interior Design, including a semester abroad in Italy, where she deepened her appreciation for global design influences.
After graduating from Auburn University’s CIDA-accredited Interior Design program in 2007, Emily moved to Atlanta, where she worked with a local design firm. During her time there, she gained valuable experience in high-end residential interiors, as well as exposure to corporate interiors, hospitality, and mixed-use buildings, including the design of a newly constructed hotel.
Emily joined JCR Design Group in the spring of 2013 and continues to grow her design expertise with each new project. Recently, she has focused on commercial office building renovations for a local real estate developer. Her residential projects range from complete kitchen and bath renovations to the design, remodeling, and furnishing of luxury condominiums.
