FROM OUR CLIENTS
We love hearing from our customers! You’re the reason we’re here and the reason we do what we do.
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!

I’ve been working with joshira for over 6 months on our project and am in absolute awe of her – our project is complex and leaves no city permitting drama untouched – but she continues to push and come with her energy and excitement. We looked for a designer for a while because at the start of our project we made the mistake and hired a rude dishonest and impatient designer who took the money and couldn’t care less about us or our project- but Joshira is the ABSOLUTE opposite- she cares so much and brings so much patience and calm and beautiful and sophisticated aesthetic to the table. She has so much knowledge in the space but her humility keeps everything at bay – because she’s focused on you and your family and your project. Working with her is not only going to win you a beautiful and thoughtful design that is right for you and your family and your needs, it’ll guarantee a new friend as well.

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 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 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 latest styles and trends. It is always a pleasure to work with Joshira and we highly recommend her.
