Not your typical bean counter, Jim has recently joined Hallmark as CFO. He’s a long-time resident of Texas, yet is relocating to Wisconsin because the cold is better than the heat, says his wife! Proud father of two, traveler, bicyclist, and foodie, Jim has a storied background in accounting.

Jim’s numbers are spot on, but his sense of humor and personality are what add up to making him a great addition to the Hallmark team.

He started in the Tyvek® business at Hallmark and then moved to VP of Sales. He led the Interiors Business Unit and is certified in Business Analytics and is Master Facilitator of the BluePrint Sales Process. When he’s not at work you’ll find him on the baseball field with his son Holden, cheering on his daughter Norah at her latest gymnastics meet or finding a great local concert with his wife Kris.

Katie Sadorf

VP Marketing & Strategy, proud MBA and alum from UW Whitewater, and Certified Scaling Up Coach are just a few of the hats Katie wears. Strategic thinking is second nature for her as she leads many cross functional initiatives, along with Hallmark’s Marketing team. 30 year veteran at Hallmark, creative mind, deep thinker, wife, and mom to two grown sons. The real boss of her life is a Black Labrador named Stella. If Katie’s not working you’ll find her planning her next international trip or traveling the globe… the world is calling and she must go.
