Family of Microsoft president Brad Smith joins Mariners ownership group

Microsoft vice chair and president Brad Smith and his wife, Kathy Surace-Smith, have purchased a stake in the Mariners ownership group, the first new partners to join the franchise since Ken Griffey Jr. in 2021. 

They are just the third new partners since the ownership formed in 1992. 

“On behalf of all of the partners, I want to welcome Kathy and Brad,” John Stanton, Mariners chair and managing partner, said in a news release. “Since this group formed in 1992, it has always been a priority to identify partners who both love baseball and are passionate about public service. Adding Kathy and Brad to our partnership strengthens our commitment to the Mariners Mission of winning championships, creating unforgettable experiences and serving our communities. 

Brad Smith has spent more than 30 years at Microsoft and was promoted to vice chair and president in 2015. 

Kathy Surace-Smith is senior VP of Human Resources and Legal Affairs at NanoString Technologies, Inc. She was previously VP & General Counsel at SonoSite Inc. and Metawave Communications. 

“We’re excited to join the Partnership Group and support the Mariners success, both on the field and in service to the community,” the couple said in a statement.
