MARRIN COSTELLO
CEO
The MC brand was born from a childhood hobby and has transformed into a global luxury lifestyle brand - with jewelry at its core. With features in Vogue, Huffington Post, In Style, US Weekly, and British GQ and over 100 retailers nationwide, it is truly humbling to see how far both I and the MC team have come. With so many new projects and brand partnerships in the words, I cannot wait to see what the future holds for the small [but mighty] MC INC business.

IN-HOUSE PHOTOGRAPHER
I’m a self taught still life and e-commerce photographer based in Los Angeles. I take the photos of the products people shop for on the MC website. I’ve known Marrin for years and to watch the progression of both her brand and her as an entrepreneur has been amazing. Collaboration is key to my success and that is no different with the MC brand. The team and I have grown together throughout the years and continue to push each other every time we work together.

MARKETING + CREATIVE
My relationship with MC felt like fate from the start. I met Marrin at a local barre studio and began my path as her assistant. With my previous background specializing in branding, marketing and fashion, my role developed as the brand continued to grow. Working and achieving with such a tight knit team is a reflection of why I was so interested in working in jewelry— family. My Poppop was a jeweler in Philadelphia and to carry on his legacy while also fulfilling my passions is a blessing.
