Retha S.

Group Fitness Instructor
Staff Bio
Retha has been employed at Galter LifeCenter since 2012.

Her certifications include:

  • MOSSA Group Blast

My favorite workout: I need weight-bearing cardio exercise because osteoporosis runs in my family, but I hate running.  Group Blast is perfect for me:  I can adjust the intensity based on how I’m feeling that day, the music and camaraderie keep me motivated, and the hour goes by fast.  

Quick Note: I joined Galter LifeCenter after trying a Group Blast class, and I ended up loving it so much I became an instructor.  When I’m not teaching Group Blast, I work as an appellate prosecutor in the Illinois Attorney General’s Office.  On weekends, I hang out with my husband and chase our two young daughters around Lincoln Square.
