Elevating Homes

& Elevating Spirits

The Bay Area's Top Interior Design Firm

You know that feeling you get when you pull on your favorite cozy sweater?


It’s soft, warm, fits perfectly and instantly makes you feel relaxed. This is what stepping into your home should feel like, and that is my goal as your interior designer. The colors and textures should please your eyes. You should easily find that spot to hang your coat, the area to kick off your shoes, and easily maneuver to the perfect place to hang your keys - all flowing with the natural hum of your life. We’ll help your home function well while elevating your spirit.

Meet Janine

Principal Designer at JAS Interior Designs. A self-professed chatterbox who loves a good plaid as much as a luxury glam chandelier. Her story takes you across the country starting at her humble east coast childhood. 


..."I worked in tech and banking and although I enjoyed finding ways to better the businesses I worked for, my creative side yearned to come out. I stumbled upon Interior Design later in my career and fell madly in love..."

My 5 Phase Design System is much like creating a Michaelangelo. At first it’s just a pile of stone, but once we begin chiseling, a masterpiece emerges. Here is a sample of what you can expect.

Passionate about plaid? Enjoy antique furniture or are you looking for modern inspirational design? At JAS Interior Designs, we have experience in a whole spectrum of styles.

Offering a variety of interior design and decorating services for residential as well as hospitality applications. See below for a full list.
