Isaac Nichelson 

Fashion Sustainability Expert/Founder

A father of three, and the founder of Sustainable Source Studios in Los Angeles, Isaac Nichelson is known as a longtime promoter of sustainability in the global fashion industry.

Born into the back-to-the-land movement of the early 1970’s, Isaac possesses and inherent love of nature, and the authentic sprit of an activist. A visionary and innovative approach to design and manufacture has allowed Isaac to help instigate and propel global trends in style and textile sustainability for more than two decades.

In 2007, California Apparel News dubbed Nichelson the “Eco-Johnny Appleseed” due to his growing reputation for being a very passionate and committed early-stage promoter of sustainable textiles and fashion.


As a creative entrepreneur with nearly 25 years of apparel industry experience, Isaac has built and led brands, and prior to that worked hands-on as a designer, marketer and salesman. This has provided Isaac a truly comprehensive knowledge base, one that extends from the origins of fiber, to yarn and textile formation, to design and manufacture--- all the way through the branding, marketing and global distribution fashion products.
