Weiss Design Group, Inc. was founded in 1993 by Brenda Weiss. Originally the focus of the design firm was healthcare design, but over the years it has expanded to include a range of interior design service areas including residential, commercial, healthcare and hospitality. Brenda Weiss is also a partner in Florida Design & Interiors Group which builds high-end residential homes in South Florida.

In 2006, Brenda launched a new group of companies which provides design services for individuals and companies who either do not want or cannot afford to hire a full-service interior designer.  These services include:

WDG Colorings: Providing professional color consulting services for commercial and residential spaces that need an interior "make-over" without a complete redesign of the space and materials.

RoomxRoom Design: This service is geared towards individuals on a budget who none the less want an experts advice and assistance in decorating a single room or their entire house.

Fix Ugly Rooms: A fun and easy way to get design advice for a room in your house. Upload a picture of a space that you want to re-decorate and Brenda and the online community will give you advice. Then upload a picture of the finished space for more comments!
