Sublime is proud to be the 2018 Region 17 Fourth Place Medalist Quartet!

We began singing together for fun in 2015, learned a song together and loved how it sounded! So, we decided to take the plunge and learn a bunch more.


We are members of 3 chorus in 3 different regions of Sweet Adelines!

Tenor Rachel Lundberg joined Sublime in the summer of 2017 following the resignation of our original tenor, Melissa Gast.  A long-time member of Sweet Adelines, Rachel is a member of Fenton Lakes Chorus (Fenton, MI) in Region 2.

Lead Sherry Berkley joined Sweet Adelines in 1982 and lives in South Bend, IN. She currently is the associate director and a lead section leader of the Grand Rapids Chorus (Region 17) and also is a member of the Melodeers Chorus (Region 3) in Northfield, IL.

Baritone Emily Oppenhuizen has been a Sweet Adeline since 2007. She joined the Grand Rapids Chorus in 2015 after moving back to the area from the east side of Michigan where she was a member of the Fenton Lakes Chorus. She is currently one of the baritone section leaders.

Bass Diane Picken has been a member of Sweet Adelines since 2008 and lives in the Kalamazoo area. She is currently one of the chorus bass section leaders.
