Callen has been a part of the Sleep Number executive leadership team since April 2014, overseeing the company’s financial performance during its transition from mattress retailer to wellness technology leader.

Prior to joining Sleep Number, Krusmark served in the assurance and advisory practices as a Certified Public Accountant with EY and Arthur Andersen. Sleep Number has retained Korn Ferry, a leading executive search firm, to conduct a search for a permanent CFO.
