Stephanie Whitlow, chief marketing officer, Western Alliance Bank

Background: Whitlow is chief marketing officer at Western Alliance Bank, where she leads strategic brand, growth and communications initiatives. With a track record of driving measurable impact, she brings a data-driven, results-oriented approach to building high-performing teams and elevating market presence.

Advice to younger self: “Stop confusing perfection with success. Growth comes from being willing to learn, adapt and keep moving forward — not from never making mistakes.”

Surprising fact: “People are often surprised that outside of the corporate world, I’m deeply creative. I love designing experiences, whether through hosting a dinner party and creating tablescapes or even baking homemade sourdough bread. I think creativity and strategy go hand in hand.”
