The Mercer Island Senior Service Club is holding a blood drive with the Puget Sound Blood Center this Friday, April 27.

The public is welcome — just check in at the school office at the main entrance.

The drive will run from 8 a.m. to 2 p.m., but will be closed for lunch from 10:30 to 11:15 a.m.

Sign-ups are being held until April 26 at the school for students during both lunches. Students must be at least 16 years old to donate, with parent permission.
