Greg Sieck



Given the depth of his experience, the size of the assignments he’s taken on and the success his clients have found, it’s fair to call Greg Sieck a marketing expert.

Fair, yet somehow insufficient.  With a resume that includes long stretches at global ad giants JWT and FCB, he’s led destiny-changing initiatives for household name brands.  These included the category-altering creation of AT&T Digital One Rate, the launch of Lucent spinoff Avaya and the Think Outside The Bun platform for Taco Bell (which helped reverse a long-term sales decline that accompanied the ads with that dog in them). 

After his agency years, Greg went client side for a spell, taking on the Vice President Brand and Advertising job at Intel, where he led the global launch of the Centrino product platform.  In 2004, Greg created the West Coast business and marketing consultancy, SieckGrowth, with a client roster that has included Applied Materials, Dolby, Electronic Arts and more.  In 2013, he joined Mark Lantz in founding Factory.  Here, he’s responsible for all things business and operations.  Greg lives in Mill Valley, north of the Golden Gate Bridge.
