"Working with Casandra has been a pleasure. We are currently in the middle of a large renovation consisting of an addition to our 2nd floor, building a master bathroom, master closet, remodeling an existing bathroom, and several other interior jobs. In addition, we are installing a lap pool in our backyard along with a complete landscape makeover back to front. We are also building a stucco wall in the front along with installing an iron driveway gate. She has presented us with some very unique design options in order to stay compliant with sometimes demanding historical area design requirements. Her designs have been amazing and her assistance with working with the City has been invaluable. We have made many changes during this process and she has been extremely patient and accommodating during this process. I am very excited about the project and I’m looking forward to seeing the final product! "

"Joshira, owner of Design by Casandra, did a fabulous job on my house. We entrusted her with the design of my living room, kitchen, master bedroom, and the room of my 13-year-old son; the result was phenomenal. Very professional and dedicated, she perfectly understood what we were looking for and put effort into every detail. I couldn’t be happier with my place; I recommend her 100%."
Joshira is an excellent and very professional designer. She has decorated our entire house, including the patio. Her designs are exciting and functional, always looking to make the house cozy and elegant. Joshira understands the personality and needs of each family member to ensure each room portrays a unique style and feeling. She keeps up to date with the latest styles and trends. It is always a pleasure to work with Joshira, and we highly recommend her.
