About F23

F23 is a marketing agency in Walnut Creek, California. It offers advertising, collateral design and website development, and adapts its services to each client.

What F23 offers

  • Advertising — campaigns in whichever form suits the client.
  • Collateral design — print pieces and email marketing.
  • Website development — sites where the code and the strategy matter as much as the appearance.

Who it works with

The agency's older site showed a website redesign for a pharmaceutical company among its examples. The current domain now displays a for-sale notice, so this profile reflects earlier stored information and its operating status should be checked.
