The Mariners Wives are dedicated to making an impact in the Seattle community by working with a variety of youth-oriented organizations. Throughout the 2018 season, the Mariners Wives volunteered their time by engaging in hospital visits, providing makeovers, facilitating art therapy projects, helping raise funds for Mariners Care, and more. The primary goal of Mariners Wives Charities is to provide support to a variety of organizations through a dedication of time, resources, and effort both at the ballpark and in the surrounding community.
In 2018, the Mariners Wives set a goal to collectively volunteer one hour for every game in a Major League regular season. The Mariners Wives exceeded their original goal of 162 hours by collectively volunteering over 278 hours throughout the season.
