Our Stylists

Neil Shivers

Lead Hair Stylist, Owner

After years of working in a series of assembly-line salons, Neil decided to open G-SQUARED with a different vision: a relaxing experience for both color & cutting by one stylist, instead of a team of stylists.

Ten years later, G-SQUARED is going strong with mentions as “Best Colorist in San Francisco” in Allure Magazine in 2006.

While color is his focus, he loves to cut and his collection of advanced education by Toni & Guy, Vidal Sassoon, The Doves and others gives him a unique insight to hair from many perspectives.


Susan Hollister

Hair Stylist

An east coast transplant, Susan joined the G-SQUARED team in 2005. Through the last 8 years of her career, she has advanced her knowledge with many cutting and color technique courses.

Susan has a clientele with various lengths and needs of hair, but caters to many of our clients with long and extra long hair. She takes the time to take care of the special needs of these clients with gentle color and extra conditioning treatments.


Cecilia Cortez

Hair Stylist

Cecilia is a bay area native with over 20 years experience in the hair industry. She specializes in both color and highlights with advanced training in color by Wella specialists. She is also certified for Brazilian Blowouts.

Her hair passion would be highlights. She has clients from all over the Bay Area who make the journey to San Francisco for highlights with Cecilia.

Allure Magazine

BEST COLORIST IN SAN FRANCISCO – “We have high standards for hair color: We want a shade that’s natural but also bold; something that will breeak us out of our rut but will still be easy to maintain. To grant our wishes, Shivers used a vibrant blend of copper and brown a bit deeper than our natural color. The translucent tint preserved our hair’s natural variations and left our curls shinier than we’d ever thought possible. We may have placed a tall order, but Shivers truly delivered.”
