While at Brown, Sienna was a Jackie Robinson Foundation scholar and Mark Roesler/CMG was her sponsor. Before working at CMG Sienna worked at production companies such as Sidney Kimmel Entertainment and Film Rites. A fourth generation Californian, Sienna is based in our Los Angeles office and specializes in Entertainment, Sports, and African American history.

Sienna is a champion of diversity & inclusion and has spoken about the topic on various news outlets such as NPR and Spectrum News. At CMG Sienna analyzes the intersection of marketing efforts, brand partnerships, and content creation to crystallize our client’s illustrious legacies and instill them within younger generations. Sienna fosters meaningful relationships with our clients, such as the family of Jackie Robinson who she has known for over 7 years. Working alongside Major League Baseball, UCLA and licensees such as Fanatics, New Era, Budweiser and Mitchell & Ness, Sienna coordinated Jackie’s Centennial celebrations which lasted for all of 2019.


Sienna oversees many of CMG’s sports legends such as Lou Gehrig, Arthur Ashe, and Bart Starr, our stars of the silver screen such as James Dean and Dorothy Dandridge, as well as CMG’s iconic African American icons such as Maya Angelou, Malcolm X, Aaliyah, and Josephine Baker. On behalf of the Rosa and Raymond Parks Institute for Self Development Sienna coordinated a Rosa Parks Barbie doll as part of Barbie’s Inspirational Women Series, a Rosa Parks statue that was erected in honor of Montgomery’s Bicentennial, as well as an exhibit of Rosa Parks’s personal papers and photographs at the Library of Congress.
